Home Health Glossary
Plain-language definitions of the terms home health agencies work with every day: PDGM, OASIS, LUPA, HHVBP, NOAs, and more.
30-Day Payment Period
The 30-day payment period is the unit of payment for Medicare home health under the Patient-Driven Groupings Model (PDGM). Each period is independently classified into one of 432 case-mix groups and billed on its own claim, with two payment periods fitting inside each 60-day certification period.
30-Day Readmission
A 30-day readmission is an unplanned return to an acute care hospital within 30 days of an inpatient discharge. Medicare tracks readmissions at both the hospital and post-acute level, and the metric shapes referral relationships, value-based payment adjustments, and public quality reporting. For home health agencies, keeping recently discharged patients out of the hospital is both a clinical responsibility and a growth strategy.
36-Month Rule
The 36-month rule is a Medicare enrollment regulation (42 CFR 424.550(b)) that applies when majority ownership of a home health agency changes within 36 months of its initial enrollment or its most recent change in majority ownership. When triggered, the Medicare provider agreement and billing privileges do not transfer to the buyer, who must instead enroll as a brand-new provider and complete a new state survey or accreditation.
5-Day Assessment Window
The 5-day assessment window is the regulatory deadline for completing the start of care comprehensive assessment, including the OASIS: within 5 days after the start of care date, where the SOC date counts as day 0. A parallel 5-day window applies at recertification, when the assessment must be completed during the last 5 days of each 60-day certification period.
60-Day Certification Period
The 60-day certification period is the length of time a physician or allowed practitioner certifies a patient's need for home health care in a single certification. Under PDGM (the Patient-Driven Groupings Model), each 60-day certification period contains two 30-day payment periods. Care continuing beyond day 60 requires a recertification, supported by a recertification OASIS assessment and an updated plan of care.
ABN (Advance Beneficiary Notice)
An Advance Beneficiary Notice of Non-coverage (ABN, Form CMS-R-131) is a standardized notice a home health agency gives an original Medicare patient before furnishing care the agency believes Medicare will not pay for. A properly executed ABN explains why coverage is expected to be denied and what the care will cost, and it lets the patient choose whether to receive and pay for the care. Without a valid ABN, the agency usually cannot bill the patient after a Medicare denial.
Accreditation (ACHC, CHAP, TJC)
Accreditation is a voluntary evaluation in which a CMS-approved accrediting organization certifies that a home health agency meets standards that meet or exceed the Medicare Conditions of Participation. For home health, the three accreditors with CMS deeming authority are the Accreditation Commission for Health Care (ACHC), Community Health Accreditation Partner (CHAP), and The Joint Commission (TJC). Accredited agencies with deemed status are surveyed by their accreditor instead of the state for routine certification purposes.
ACO (Accountable Care Organization)
An Accountable Care Organization (ACO) is a group of physicians, hospitals, and other providers that accepts joint accountability for the total cost and quality of care for an attributed Medicare population. Because post-acute spending and readmissions are among an ACO's biggest savings levers, ACOs increasingly steer patients toward high-performing home health partners.
Acute Care Hospitalization Rate
The acute care hospitalization (ACH) rate is the percentage of home health stays during which the patient was admitted to an acute care hospital, historically measured over the first 60 days of home health. It is a claims-based, risk-adjusted measure that served for years as the industry's headline utilization metric before CMS began shifting to the Potentially Preventable Hospitalization measure.
ADLs (Activities of Daily Living)
Activities of daily living (ADLs) are the basic self-care tasks a person performs every day: bathing, dressing, grooming, toileting, transferring, walking, and eating. In home health, ADL performance is scored at every OASIS assessment and drives the functional impairment level under PDGM as well as several publicly reported quality measures.
Admission Source
Admission source is the Patient-Driven Groupings Model (PDGM) variable that classifies each 30-day payment period as institutional or community. A period is institutional when the patient was discharged from a qualifying inpatient setting within the 14 days before home health admission, and institutional periods carry higher case-mix weights because those patients typically need more resources.
Admission Volume
Admission volume is the number of new patients a home health agency admits in a given period, counted at the completed start of care visit. It is the top of the census engine: admissions minus discharges determines whether the agency grows, and nearly every growth initiative ultimately has to show up in this number.
ADR (Additional Documentation Request)
An Additional Documentation Request (ADR) is a formal request from a Medicare review contractor, most often the Medicare Administrative Contractor (MAC), asking a provider to submit medical records that support a claim selected for review. For home health agencies, an ADR typically requires the plan of care, face-to-face documentation, OASIS, visit notes, and orders. Missing the response deadline, generally 45 days for MAC reviews, results in an automatic denial.
Adverse Event Measures
Adverse event measures are OASIS-derived quality indicators that flag rare, potentially preventable negative outcomes, such as emergent care for an injury caused by a fall or a substantial decline in function during the episode. Unlike publicly reported outcome measures, they are designed as internal warning signals: each flagged case is meant to trigger a chart review, not a rate comparison.
AI in Home Health
Artificial intelligence (AI) in home health is the application of machine learning and large language models to agency workflows: drafting visit documentation, suggesting ICD-10 codes, flagging OASIS inconsistencies, optimizing schedules, and predicting hospitalization risk. Adoption accelerated sharply after 2023 as language models became capable of handling clinical narrative, the dominant data type in home health.
Allowed Practitioners (NP, PA, CNS)
Allowed practitioners are nurse practitioners (NPs), physician assistants (PAs), and clinical nurse specialists (CNSs) who are permitted to certify eligibility, order services, and establish and review the plan of care for Medicare home health patients. The authority was granted permanently by the CARES Act in 2020 and operates within each state's scope of practice laws.
Anti-Kickback Statute
The Anti-Kickback Statute (AKS) is a federal criminal law that prohibits knowingly offering, paying, soliciting, or receiving anything of value to induce or reward referrals of business payable by federal health care programs such as Medicare and Medicaid. Because home health agencies live on referrals, the AKS shapes how they can compensate liaisons and medical directors and how they interact with referral sources. This page is educational and general; it is not legal advice.
Average Daily Census (ADC)
Average daily census (ADC) is the average number of patients a home health agency has on service per day across a period, usually a month or quarter. It smooths out the daily churn of admissions and discharges, which makes it the standard basis for staffing models, budgets, branch comparisons, and valuation conversations.
Background Checks and Screening
Background checks and screening are the pre-hire and ongoing verifications a home health agency runs on employees and contractors: criminal history checks under state law, federal exclusion list screening, license and certification verification, and related checks such as aide registries and driving records. Because staff work alone in patients' homes, screening is both a compliance obligation and a core patient-safety control, and several checks must be repeated on an ongoing basis rather than done once at hire.
Benchmarking
Benchmarking is the practice of comparing an agency's performance against external reference points such as national or state averages, peer cohorts, or payment-model targets. In home health it spans quality measures, financial indicators, and operational throughput. Under the expanded Home Health Value-Based Purchasing (HHVBP) model, benchmarking is no longer optional analysis: how you compare to your cohort directly determines payment.
BIMS (Brief Interview for Mental Status)
The BIMS (Brief Interview for Mental Status) is a short, standardized cognitive screening interview included in OASIS Section C. It tests word repetition, temporal orientation, and delayed recall, producing a summary score from 0 to 15 that stratifies patients as cognitively intact, moderately impaired, or severely impaired, and it aligns home health cognitive screening with the tools used in nursing facilities and other post-acute settings.
Branch Operations
Branch operations refers to running additional home health locations that serve a portion of the parent agency's service area under the parent's Medicare certification and provider number. A branch shares administration, supervision, and services with the parent rather than operating independently. Branches are the standard way to extend geographic reach without certifying a new agency.
Bundled Payments (BPCI)
Bundled payments pay a single target price for an entire episode of care, such as a joint replacement plus everything that follows for 30 to 90 days, rather than paying each provider separately. Medicare tested this through the Bundled Payments for Care Improvement (BPCI) initiative and BPCI Advanced. Because post-acute care is where episode spending varies most, home health agencies that deliver good outcomes at lower cost than facility care are natural winners under bundles.
Care Compare
Care Compare is the Medicare.gov website where CMS publicly reports quality data for home health agencies and other provider types. For home health, it displays the Quality of Patient Care Star Rating, the Patient Survey Star Rating, and individual quality measure results drawn from OASIS assessments, Medicare claims, and HHCAHPS surveys.
Care Coordination
Care coordination in home health is the active integration of everyone involved in a patient's care: agency disciplines, the certifying practitioner, other treating providers, the patient, and caregivers, all working from one current plan of care. It is an explicit Medicare Condition of Participation, and failures of coordination are among the most commonly cited deficiencies in home health surveys.
Care Transitions
Care transitions are the handoffs patients experience when moving between care settings, such as from a hospital or skilled nursing facility to home health. They are the riskiest moments in a patient's episode, when medication errors, missed orders, and delayed care cluster. For home health agencies, executing transitions well is both a safety imperative and the single strongest argument for winning referrals from hospitals and health systems.
Caregiver Burden
Caregiver burden is the cumulative physical, emotional, and financial strain experienced by family members and other unpaid caregivers supporting a patient at home. Because the home health model depends on caregivers to carry the plan of care between visits, caregiver breakdown is one of the most common reasons home-based care fails and patients end up hospitalized or placed in facilities.
Case Conference
A case conference is a documented discussion among the disciplines caring for a home health patient, covering current status, progress toward goals, problems, and needed changes to the plan of care. Case conferences are the standard evidence agencies use to demonstrate the interdisciplinary coordination that Medicare's Conditions of Participation require.
Case Management
Case management in home health is the practice of assigning one clinician, usually a registered nurse, ownership of a patient's entire episode: coordinating all disciplines, keeping orders and the plan of care current, monitoring progress toward goals, and managing the path to discharge. It is the operating model most agencies use to satisfy Medicare's care coordination requirements and keep episodes clinically and financially on track.
Case Rate
A case rate is a fixed payment negotiated with a payer that covers all home health services for a defined case, usually an episode of set length, no matter how many visits the agency delivers. It is a common alternative to per-visit payment in Medicare Advantage and commercial contracts. Because case rates transfer utilization risk to the agency, pricing them requires reliable cost and utilization data.
Case-Mix Weight
A case-mix weight is the numeric multiplier assigned to each of the 432 case-mix groups under the Patient-Driven Groupings Model (PDGM). It scales the national standardized 30-day base payment rate up or down to reflect the expected resource intensity of patients in that group, making it the single biggest driver of what a period pays.
Caseload Management
Caseload management is the practice of assigning and balancing patients across home health clinicians so that ordered visit frequencies, assessment windows, and care coordination duties are all met without overloading any one person. A caseload is measured not just in patient count but in acuity, visit frequency, geography, and documentation load. Done well, it is invisible; done poorly, it shows up as missed visits, late OASIS, and resignations.
Catheter and Ostomy Care
Catheter and ostomy care covers the skilled nursing services that maintain urinary catheters and bowel or urinary diversions in the home, including catheter changes, stoma assessment, pouching, and complication management. Medicare recognizes this care as inherently skilled, and it anchors many long-running home health episodes.
Census
Census is the number of patients a home health agency has on service at a point in time, counted from start of care through discharge. It is the headline measure of agency size and the base that revenue, staffing, and fixed-cost leverage are all built on, which is why growth conversations in home health almost always start with census.
Change of Ownership (CHOW)
A change of ownership (CHOW) occurs when a Medicare-certified home health agency's ownership transfers to a new entity in a way that meets the regulatory definition at 42 CFR 489.18, such as an asset sale, merger, or consolidation. In a standard CHOW the Medicare provider agreement automatically transfers to the buyer, and with it successor liability for the seller's Medicare obligations, including overpayments.
Chronic Care Management
Chronic care management is the coordinated, ongoing care of patients with multiple long-term conditions such as heart failure, diabetes, and COPD. In home health it describes a clinical approach rather than a billing code: agencies manage chronic disease within an episodic, intermittent benefit, which creates both clinical opportunity and coverage tension.
Claims-Based Measures
Claims-based measures are quality metrics that CMS calculates from Medicare fee-for-service claims rather than from assessments or surveys, requiring no separate data submission by the agency. In home health they capture hospital and emergency department use, discharge to community, and spending efficiency, and they carry 40% of the HHVBP Total Performance Score in the CY2026 measure set.
Clean Claim
A clean claim is a claim submitted with complete, accurate information that the payer can adjudicate and pay on first pass, with no rejections, requests for more information, or manual intervention. Clean claim rate, the share of claims that pay first time, is one of the most telling indicators of a home health agency's revenue cycle health, since every claim that is not clean adds cost, delay, and denial risk.
Clinical Decision Support
Clinical decision support (CDS) is software that surfaces patient-specific guidance inside clinical workflows, such as medication interaction alerts, OASIS consistency checks, wound care protocol prompts, and risk flags. In home health, CDS matters because field clinicians work alone in patients' homes without a colleague down the hall to consult, making the EHR the main channel for real-time clinical guidance.
Clinical Grouping
Clinical grouping is the Patient-Driven Groupings Model (PDGM) variable that assigns each 30-day payment period to one of 12 categories based on the principal diagnosis reported on the claim. The group reflects the primary reason for home health care and shapes the period's case-mix weight, functional thresholds, and LUPA threshold.
Clinical Manager
The clinical manager is a role required by the Medicare home health Conditions of Participation (CoPs): one or more qualified individuals who oversee all patient care services and personnel. The clinical manager coordinates referrals, makes patient and personnel assignments, and ensures that plans of care are developed, followed, and updated. In most agencies it is the operational hinge between field clinicians and agency leadership.
Clinician Retention
Clinician retention is an agency's ability to keep its nurses, therapists, and aides over time, usually measured as annual retention or turnover rate. In home health, retention is an operating constraint as much as an HR metric: capacity to admit patients is capped by field staff, so every departure translates into declined referrals, disrupted continuity, and recruiting cost. Documentation burden, pay volatility, and windshield time are the recurring reasons clinicians leave.
CMS (Centers for Medicare & Medicaid Services)
The Centers for Medicare & Medicaid Services (CMS) is the federal agency within the Department of Health and Human Services that administers Medicare, Medicaid, and the Children's Health Insurance Program. For home health agencies, CMS sets the Conditions of Participation, payment policy under the Home Health Prospective Payment System, OASIS and quality reporting requirements, and program integrity rules. Nearly every operational requirement in a Medicare-certified agency traces back to CMS.
Coding Automation
Coding automation is the use of software, increasingly AI-driven, to read referral documents, assessments, and clinical notes and suggest ICD-10 diagnosis codes for a home health episode. It compresses a process that traditionally required outsourced coders and multi-day turnaround, while leaving final code assignment to a qualified human reviewer.
Community Liaison
A community liaison is a home health agency's field-based business development representative, responsible for building and maintaining referral relationships across a territory: skilled nursing facilities, assisted living communities, physician practices, hospitals, and community organizations. Liaisons are the human layer of an agency's growth engine, translating operational performance into referral volume.
Comorbidity Adjustment
The comorbidity adjustment is the Patient-Driven Groupings Model (PDGM) variable that adjusts a 30-day period's payment based on the patient's secondary diagnoses. Periods are classified as no adjustment, low, or high, with the tiers reflecting how much documented comorbid conditions are expected to increase the cost of care.
Competency Evaluation
Competency evaluation is the documented process of verifying that home health personnel can safely and effectively perform the tasks their role requires. The Medicare Conditions of Participation (CoPs) require agencies to employ qualified, competent staff, with detailed evaluation requirements for home health aides in particular. Competency files are a standard stop on every state survey, and gaps in them are among the most common personnel-related citations.
Comprehensive Assessment
The comprehensive assessment is the full patient evaluation that the Medicare Conditions of Participation require home health agencies to complete for every patient, regardless of payer. It must be completed within 5 days after the start of care date and includes clinical, functional, psychosocial, and medication content, a drug regimen review, and, for Medicare and Medicaid patients, the OASIS items.
Condition-Level Deficiency
A condition-level deficiency is a survey finding that a home health agency is out of compliance with an entire Condition of Participation, not just an individual standard within it. It is the most serious routine survey outcome short of immediate jeopardy, and it starts a termination track: the agency loses Medicare participation within 90 days (23 days under immediate jeopardy) unless compliance is restored and verified. CMS can also impose alternative sanctions alongside the termination timeline.
Conditions of Participation (CoPs)
The Conditions of Participation (CoPs) are the federal health and safety requirements that home health agencies must meet to participate in Medicare and Medicaid. They are codified at 42 CFR Part 484 and cover patient rights, comprehensive assessment, care planning, skilled services, quality improvement, and agency administration. State surveyors and accrediting organizations measure agencies against the CoPs, and serious noncompliance can end an agency's ability to bill Medicare.
Consolidated Billing
Consolidated billing is the Medicare rule that makes the home health agency responsible for billing virtually all covered home health services for a patient under its plan of care. While a home health period is open, other providers generally cannot bill Medicare separately for bundled services and must look to the agency for payment instead.
Cost Per Visit
Cost per visit is the total cost a home health agency incurs to deliver a single visit, calculated either as direct cost (clinician pay, mileage, supplies) or fully loaded cost including clinical management, back office, and overhead. It is the unit economic that connects staffing decisions to margin, and the benchmark against which per-visit payer rates and LUPA payments have to be judged.
Days Sales Outstanding (DSO)
Days Sales Outstanding (DSO), often called days in accounts receivable, measures the average number of days between earning revenue and collecting the cash. It is typically calculated as accounts receivable divided by average daily revenue. For home health agencies, DSO is the headline cash flow metric, because payroll comes due every one to two weeks regardless of when Medicare, Medicare Advantage plans, and other payers actually pay.
Deemed Status
Deemed status means CMS accepts a home health agency's accreditation by a CMS-approved accrediting organization as evidence that the agency meets the Medicare Conditions of Participation. Agencies with deemed status are surveyed by their accreditor (ACHC, CHAP, or The Joint Commission) instead of the state survey agency for routine certification purposes. Complaint investigations, validation surveys, and CMS enforcement authority remain fully in place.
Denials Management
Denials management is the systematic process of preventing, tracking, appealing, and eliminating the root causes of denied and rejected claims. In home health, denials cluster around eligibility documentation, untimely filings, authorization gaps with Medicare Advantage plans, and technical errors, and a mature denials program treats each denial as both revenue to recover and a defect signal to fix upstream.
Director of Nursing (DON)
The Director of Nursing (DON), in some states titled Director of Patient Care Services, is the senior nursing leader of a home health agency, responsible for clinical standards, nursing practice, and clinical staff oversight. The title comes from state licensure rules rather than the federal Conditions of Participation, which instead define clinical manager and administrator roles, but many states require a DON with specific qualifications. The DON is typically the agency's clinical backbone and a key figure in every survey.
Discharge Assessment
The discharge assessment is the OASIS completed when a patient is discharged from home health care, other than by death or transfer to an inpatient facility. It must be completed within 2 calendar days of the discharge date, and it captures the patient's end-of-care status that CMS compares against admission to calculate outcome measures.
Discharge Planning
Discharge planning is the process of preparing a home health patient to leave agency care safely, whether goals are met, eligibility ends, or care transfers to another setting. It is governed by a Medicare Condition of Participation with specific communication requirements, and it begins at admission, not in the final week of the episode.
Discharged to Community (DTC)
Discharged to Community (DTC) is a claims-based quality measure assessing whether home health patients were discharged to the community and remained there safely, without an unplanned hospital admission or death in the 31 days following discharge. The post-acute care version, DTC-PAC, is used in home health public reporting and joined the expanded HHVBP measure set with the CY2025 performance year.
Disease Management Programs
Disease management programs are standardized clinical pathways that home health agencies build around high-volume, high-risk conditions such as heart failure, COPD, and diabetes. They combine visit protocols, teaching tools, symptom monitoring, and escalation rules so that care for a given diagnosis is consistent across clinicians rather than dependent on individual habits.
Documentation Burden
Documentation burden is the administrative load clinicians carry to record care: visit notes, comprehensive assessments, care plans, and compliance paperwork. In home health the burden is unusually heavy because every visit generates standalone documentation, OASIS assessments run to dozens of items, and payment and survey compliance both depend on the completeness of what gets written.
Drug Regimen Review
The drug regimen review (DRR) is the required clinical screen of a home health patient's complete medication regimen for potentially clinically significant issues, such as interactions, duplications, omissions, adverse reactions, and noncompliance. It is part of the comprehensive assessment under the Conditions of Participation and is documented through OASIS items M2001, M2003, and M2005, which also feed a federal process measure.
Dual Eligibles
Dual eligibles are people enrolled in both Medicare and Medicaid, a population of more than 12 million Americans who are disproportionately low-income, chronically ill, and heavy users of home-based care. For home health agencies, duals are a core patient segment: Medicare pays first for the skilled episode while Medicaid wraps around with cost-sharing protection and long-term services and supports.
Durable Medical Equipment (DME)
Durable medical equipment (DME) is reusable equipment that serves a medical purpose and is appropriate for use in the home, such as walkers, wheelchairs, hospital beds, oxygen equipment, and infusion pumps. Medicare covers DME under Part B when a practitioner orders it, and home health clinicians are often the ones who identify the need and coordinate delivery.
E-Referral Platforms
E-referral platforms are electronic systems that hospitals and health systems use to send post-acute referrals to home health agencies, SNFs, and other providers, and to compare responses in real time. For agencies, they are both a referral firehose and a scoreboard: the same platform that delivers referrals also tracks how fast and how often the agency says yes.
Eligibility Verification
Eligibility verification is the process of confirming a patient's insurance coverage and benefit status before and during a home health episode. For Medicare patients it means checking Part A and B entitlement, Medicare Advantage enrollment, hospice elections, and open home health episodes at other agencies before committing to a start of care. Skipped or shallow verification is one of the most common root causes of home health denials.
Emergency Department Use Without Hospitalization
Emergency department (ED) use without hospitalization is a claims-based home health quality measure counting the percentage of home health stays during which the patient visited an ED but was not admitted to the hospital. It flags episodes where patients sought emergency care that a well-functioning home health plan might have prevented or handled in the home.
Emergency Preparedness Rule
The Emergency Preparedness Rule is a Medicare Condition of Participation (42 CFR 484.102) requiring home health agencies to maintain an all-hazards emergency preparedness program. The program has four required elements: an emergency plan built on a documented risk assessment, supporting policies and procedures, a communication plan, and a training and testing program.
Episodic Payment
Episodic payment is a reimbursement model in which a home health agency receives one predetermined amount for an entire episode or period of care, regardless of the number of visits delivered within it. Medicare pays this way for 30-day periods under the Patient-Driven Groupings Model (PDGM), and some Medicare Advantage and commercial contracts use episodic structures as well. The model shifts utilization risk from the payer to the agency.
EVV (Electronic Visit Verification)
Electronic Visit Verification (EVV) is technology that electronically confirms that a home visit occurred, capturing who delivered the service, to whom, where, and when. The 21st Century Cures Act of 2016 required states to implement EVV for Medicaid-funded personal care services and home health services, and each state administers its own EVV program with its own systems and rules.
Face-to-Face Encounter
The face-to-face encounter is a Medicare requirement that the patient see the certifying practitioner, or another permitted clinician, within 90 days before or 30 days after the home health start of care, for a reason related to the primary reason the patient needs home health. Without a compliant, documented encounter, the certification is incomplete and the claim is not payable.
Fall Prevention
Fall prevention is the set of assessments and interventions home health teams use to reduce fall risk for patients living at home. Falls are the leading cause of injury among adults 65 and older, and preventing them protects patients while directly improving the hospitalization and safety outcomes agencies are measured on.
Fall Risk Assessment
A fall risk assessment in home health is a structured screen of a patient's likelihood of falling, performed with a standardized, validated tool as part of the comprehensive assessment. OASIS item M1910 documents whether a multi-factor fall risk assessment was conducted, and falls with injury are captured at transfer and discharge, making fall risk both a clinical priority and a measured one.
False Claims Act
The False Claims Act (FCA) is the federal government's primary tool for combating fraud against programs like Medicare and Medicaid. It imposes civil liability on anyone who knowingly submits, or causes the submission of, false or fraudulent claims for payment, with remedies that include treble damages and substantial per-claim penalties. Home health has been a sustained FCA enforcement focus for decades. This page is educational and general, not legal advice.
Final Claim
The final claim is the Medicare claim a home health agency submits after each 30-day payment period ends, reporting every visit, supply, and diagnosis for the period along with the HIPPS code that identifies its case-mix group. It is how the agency actually gets paid under the Patient-Driven Groupings Model (PDGM), since the Notice of Admission that precedes it carries no payment.
Frequency and Duration
Frequency and duration are the ordered visit pattern for each discipline on a home health plan of care: how often visits occur and for how long, written in shorthand like "SN 2wk x 4" (skilled nursing twice weekly for four weeks). Medicare requires all services to be furnished according to these orders, so the match between ordered and delivered visits is one of the most audited details in home health.
Front-Loading Visits
Front-loading visits is the practice of concentrating home health visits, usually skilled nursing, in the first one to two weeks after admission or hospital discharge, when patients are at highest risk of complications and readmission. It is an evidence-supported staffing pattern for reducing early acute care hospitalization, and under PDGM it also protects the first 30-day payment period from LUPA exposure.
Functional Decline
Functional decline is a measurable loss in a patient's ability to perform self-care and mobility tasks such as bathing, dressing, transferring, and walking. In home health it is both a clinical warning sign and a data event: OASIS captures function at every required assessment point, so decline is visible in the record and in the measures built from it.
Functional Impairment Level
Functional impairment level is the Patient-Driven Groupings Model (PDGM) variable that classifies each 30-day payment period as low, medium, or high based on responses to specific OASIS items. Higher impairment levels carry higher case-mix weights, making OASIS functional accuracy a direct driver of home health payment.
G-Codes
G-codes are Healthcare Common Procedure Coding System (HCPCS) Level II codes that Medicare uses to describe services that have no matching CPT code. In home health billing, G-codes identify the discipline and type of each visit reported on the claim, such as skilled nursing, therapy, medical social work, or home health aide services. Every billable visit line on a home health claim pairs a G-code with a revenue code and units of time.
GG Items (Functional Abilities)
GG items are the standardized functional ability items in Section GG of the OASIS, covering prior functioning, prior device use, self-care (GG0130), and mobility (GG0170). They score how much help a patient needs to complete everyday activities on a common 6-level scale used across home health, skilled nursing, inpatient rehab, and LTACH settings, and they feed federal quality measures.
Gross Margin Per Episode
Gross margin per episode is the revenue an agency collects for a patient's payment period minus the direct costs of delivering that care, chiefly clinician visit costs, mileage, and supplies. It is the core unit economics metric in home health: it tells an operator whether each admission funds overhead and growth or quietly loses money.
HCBS Waivers
Home and community-based services (HCBS) waivers, authorized mainly under Section 1915(c) of the Social Security Act, let state Medicaid programs pay for long-term services and supports in a person's home or community instead of an institution. Waivers fund services like personal care, respite, home modifications, and case management for people who meet an institutional level of care. For home health agencies, waivers are the main funding stream keeping long-term patients stable at home after skilled episodes end.
Health Literacy
Health literacy is a person's capacity to obtain, understand, and use health information to make decisions and follow care instructions. Limited health literacy is common among home health patients and is linked to medication errors, missed warning signs, and higher hospitalization rates, which is why OASIS now screens for it directly.
HETS
HETS (HIPAA Eligibility Transaction System) is the system the Centers for Medicare & Medicaid Services (CMS) uses to answer real-time Medicare eligibility inquiries from providers. Home health agencies query HETS, usually through their EHR, a clearinghouse, or a Medicare Administrative Contractor portal, to confirm a patient's Medicare Part A and B status, Medicare Advantage enrollment, hospice election periods, and other coverage details before admitting and billing.
HHCAHPS
HHCAHPS (Home Health Care Consumer Assessment of Healthcare Providers and Systems) is the standardized CMS survey that measures patients' experience of care from Medicare-certified home health agencies. Administered by approved third-party vendors, its results are publicly reported on Care Compare and feed both the Patient Survey Star Rating and the Home Health Value-Based Purchasing model.
HHCCN (Home Health Change of Care Notice)
The Home Health Change of Care Notice (HHCCN, Form CMS-10280) is a standardized notice home health agencies give original Medicare patients when the agency reduces or stops specific services listed on the plan of care while the patient continues receiving other home health care. It covers changes driven by physician orders as well as changes the agency makes for its own business reasons, such as staffing shortages.
HHRG (Home Health Resource Group)
A Home Health Resource Group (HHRG) is the case-mix group Medicare assigns to a 30-day payment period under the Patient-Driven Groupings Model (PDGM). Each of the 432 HHRGs carries a case-mix weight that determines how much the period pays, and the group is reported on the claim as a HIPPS code.
HHVBP (Home Health Value-Based Purchasing)
Home Health Value-Based Purchasing (HHVBP) is a CMS model that adjusts Medicare fee-for-service payments to home health agencies based on quality performance, with adjustments of up to plus or minus 5%. The expanded model has applied to all Medicare-certified home health agencies nationwide since January 2023, and the first payment adjustments took effect in CY2025.
HIPAA in Home Health
HIPAA (the Health Insurance Portability and Accountability Act) sets national standards for protecting patient health information, enforced through the Privacy, Security, and Breach Notification Rules. Home health agencies face distinctive HIPAA risks because protected health information (PHI) travels with clinicians into patients' homes, personal vehicles, and mobile devices rather than staying inside a facility.
HIPPS Code
A Health Insurance Prospective Payment System (HIPPS) code is the five-character code reported on a Medicare home health claim to identify the case-mix group for a 30-day payment period. It is the billing representation of the Home Health Resource Group (HHRG) and determines the case-mix weight applied to the period's payment.
Home Health Administrator
The home health administrator is the leader responsible for all day-to-day operations of a Medicare-certified agency, a role required by the Conditions of Participation (CoPs). The administrator is appointed by and reports to the agency's governing body and must meet federal qualification requirements, with many states adding licensure or training requirements of their own. The job spans clinical compliance, staffing, growth, and financial performance simultaneously.
Home Health Aide
A home health aide provides hands-on personal care such as bathing, grooming, dressing, toileting, and simple delegated tasks under a written aide care plan established by a registered nurse or therapist. Under Medicare home health, aide services are a dependent service: they are covered only while the patient also receives skilled nursing, physical therapy, occupational therapy, or speech-language pathology.
Home Health EHR
A home health electronic health record (EHR) is a software platform built for the workflows of Medicare-certified home health agencies: referral intake, OASIS assessments, visit documentation, scheduling, physician orders, quality reporting, and claims. Unlike hospital EHRs, it is organized around episodes of care delivered in the patient's home by mobile clinicians rather than around facility encounters.
Home Health Moratoria
Home health moratoria were temporary bans CMS imposed on the enrollment of new home health agencies in geographic areas with documented fraud risk, using authority created by the Affordable Care Act. CMS lifted the last home health moratoria in January 2019, but the underlying authority remains on the books, and the episode still shapes how new agencies are screened and how agency licenses are valued in former moratorium states.
Home Health PPS
The Home Health Prospective Payment System (HH PPS) is the method Medicare uses to pay home health agencies a predetermined, case-mix adjusted amount for each unit of care rather than reimbursing actual costs. Since January 2020 the unit of payment has been a 30-day period under the Patient-Driven Groupings Model (PDGM). Annual rulemaking updates the base rate, case-mix weights, wage index, and LUPA thresholds.
Home Health vs. Home Care
Home health and home care are distinct services that are constantly confused by patients, families, and even referral sources. Home health is skilled, intermittent medical care (nursing, therapy) ordered by a practitioner and covered by Medicare for homebound patients. Home care, sometimes called non-medical or private duty home care, is help with bathing, dressing, meals, and companionship, typically paid out of pocket, through Medicaid programs, or by long-term care insurance.
Home Infusion Therapy
Home infusion therapy is the administration of medications or fluids through a needle or catheter in the patient's home, including IV antibiotics, hydration, parenteral nutrition, and certain biologics. In skilled home health, nurses administer infusions, maintain vascular access, and teach patients and caregivers to manage therapy safely between visits.
Home Safety Evaluation
A home safety evaluation is a structured review of the patient's living environment to identify hazards such as fall risks, fire and oxygen dangers, unsafe medication storage, and barriers to mobility. It is part of the home health comprehensive assessment and one of the clearest advantages home-based clinicians hold: they see the environment where problems actually happen.
Homebound Status
Homebound status is a threshold eligibility requirement for the Medicare home health benefit: the patient must be confined to the home as defined in the Medicare Benefit Policy Manual, Chapter 7. The test has two parts, requiring both a qualifying reason the patient cannot readily leave home and a normal inability to leave home, with leaving requiring considerable and taxing effort. Homebound does not mean bedbound, and certain absences from home are permitted.
Hospice
Hospice is a Medicare benefit providing comfort-focused care for patients with a terminal prognosis of six months or less, as certified by two physicians. Electing hospice means the patient waives curative treatment for the terminal condition in exchange for an interdisciplinary comfort care model, usually delivered at home. For home health agencies, hospice is the most important adjacent setting: it is where many patients should transition when they stop improving.
Hospital Discharge Planner
A hospital discharge planner is the nurse, social worker, or case manager responsible for arranging post-acute services before a patient leaves the hospital. For home health agencies, discharge planners are the gatekeepers of hospital referral volume: they assemble the referral, present agency options to the patient, and decide who gets the first call.
Hospital Readmissions Reduction Program (HRRP)
The Hospital Readmissions Reduction Program (HRRP) is a Medicare program that reduces inpatient payments to hospitals with excess 30-day readmissions for specific conditions and procedures, with penalties of up to 3% of Medicare inpatient payments. Created by the Affordable Care Act and effective since fiscal year 2013, HRRP is the reason hospitals scrutinize the readmission performance of their post-acute partners, including home health agencies.
Hospital-at-Home
Hospital-at-home is a care model in which patients who would otherwise be admitted to a hospital receive inpatient-level acute care in their own homes, with daily clinician oversight, in-person nursing visits, and continuous remote monitoring. In the US it is anchored by the CMS Acute Hospital Care at Home waiver, which pays participating hospitals inpatient rates for qualifying at-home admissions.
IADLs (Instrumental Activities of Daily Living)
Instrumental activities of daily living (IADLs) are the complex tasks required to live independently: preparing meals, managing medications, handling finances, shopping, housekeeping, using transportation, and using the phone or other communication tools. IADL deficits usually appear before ADL deficits and often determine whether a patient can safely remain at home.
ICD-10 Coding in Home Health
ICD-10 coding in home health is the assignment of diagnosis codes to each patient's episode, reported on the OASIS and the claim. Under PDGM, the principal diagnosis sets the clinical grouping and secondary diagnoses set the comorbidity adjustment, so coding accuracy directly determines payment, audit exposure, and how patient complexity appears in quality data.
Immediate Jeopardy
Immediate jeopardy (IJ) is the most severe survey determination: a finding that a provider's noncompliance has caused, or is likely to cause, serious injury, harm, impairment, or death to a patient. For a home health agency, an IJ finding compresses the Medicare termination timeline to 23 days unless the jeopardy is removed, and it demands immediate action rather than routine correction.
Improvement in Ambulation
Improvement in ambulation is an OASIS-based home health outcome measure showing the percentage of quality episodes in which a patient's ability to walk or move safely improved between the start or resumption of care assessment and discharge. It is risk-adjusted, publicly reported, and feeds the Quality of Patient Care Star Rating on Care Compare.
Improvement in Dyspnea
Improvement in dyspnea is an OASIS-based home health outcome measure showing the percentage of quality episodes in which a patient became less short of breath between the start or resumption of care assessment and discharge. It is risk-adjusted and has long featured in home health public reporting and quality programs as the leading respiratory outcome.
Improvement in Self-Care
Improvement in self-care refers to the family of OASIS-based home health outcome measures tracking whether patients gained independence in activities of daily living, such as bathing, dressing, and managing oral medications, between the start or resumption of care and discharge. Self-care outcomes gained weight in the expanded HHVBP model, whose CY2026 measure set adds new bathing and dressing function measures to the OASIS-based category.
In-Service Training
In-service training is the ongoing education an agency provides to keep staff skills and knowledge current. The Medicare Conditions of Participation set a hard floor for home health aides: at least 12 hours of in-service training in each 12-month period. Beyond the aide requirement, in-services are how agencies keep a dispersed field workforce aligned on clinical practice, regulatory changes, and documentation standards.
Infection Control in Home Health
Infection control in home health is the program of prevention, surveillance, and education that protects patients and staff from infection in a setting the agency does not control. The Medicare Conditions of Participation require every agency to maintain an infection prevention and control program that follows accepted standards of practice.
Inpatient Rehabilitation Facility (IRF)
An inpatient rehabilitation facility (IRF) is a hospital or hospital unit that provides intensive, physician-supervised rehabilitation, typically at least three hours of therapy per day, five days a week. IRFs serve patients recovering from events like stroke, brain injury, and major trauma who can tolerate and benefit from intensive rehab. For home health agencies, IRF discharges are high-value, therapy-heavy referrals with an institutional admission source under PDGM.
Interdisciplinary Team
The interdisciplinary team (IDT) in home health is the group of clinicians and support staff caring for a single patient: nursing, physical, occupational, and speech therapy, medical social work, home health aides, and the clinical manager, all working under one physician-approved plan of care. Medicare's Conditions of Participation require these disciplines to communicate and coordinate so the patient receives one integrated program of care, not several parallel ones.
Interoperability in Home Health
Interoperability in home health is the ability of an agency's systems to exchange patient information electronically with hospitals, physicians, pharmacies, payers, and health information networks. It covers everything from receiving referral documents and hospital discharge summaries to sending visit information back to the referring physician, and it remains a weak point across post-acute care.
iQIES
iQIES, the Internet Quality Improvement and Evaluation System, is the CMS platform through which home health agencies submit OASIS assessment data and access validation and quality reports. Home health agencies moved to iQIES in January 2020, replacing the legacy QIES and CASPER infrastructure, and the system also supports survey and certification functions used by CMS and state agencies.
LTACH (Long-Term Acute Care Hospital)
A long-term acute care hospital (LTACH, also written LTCH) is a hospital certified to treat medically complex patients who need extended hospital-level care, with an average length of stay above 25 days. Typical LTACH patients include ventilator weaning cases, complex wounds, and multi-system failures. For home health agencies, LTACH discharges are low-volume but very high-acuity referrals that test an agency's clinical depth.
LUPA (Low Utilization Payment Adjustment)
A Low Utilization Payment Adjustment (LUPA) occurs when the number of visits in a 30-day payment period falls below the threshold for the period's case-mix group. Instead of the full period payment, Medicare pays national per-visit rates for the visits actually delivered, which typically totals a fraction of the case-mix amount.
LUPA Threshold
The LUPA threshold is the minimum number of visits a home health agency must deliver in a 30-day payment period to receive the full case-mix payment under the Patient-Driven Groupings Model (PDGM). Thresholds vary by case-mix group, ranging from 2 to 6 visits, and periods that fall short are paid per visit as a Low Utilization Payment Adjustment (LUPA).
M Items
M items are the OASIS data elements whose identifiers begin with M, the instrument's original numbering scheme, such as M0030 (start of care date), M1021 (primary diagnosis), and the M1800-series functional items. They remain the backbone of OASIS even as newer cross-setting sections with letter prefixes like GG, C, and D have been layered in.
MAC (Medicare Administrative Contractor)
A Medicare Administrative Contractor (MAC) is a private company that CMS contracts with to process Medicare fee-for-service claims and administer the program within a defined jurisdiction. Home health and hospice claims are handled by dedicated HH+H MACs: Palmetto GBA, CGS Administrators, and National Government Services, each serving an assigned group of states. Your MAC is the operational front door for claims, NOAs, medical review, and first-level appeals.
Managed Care Contracting
Managed care contracting is the process of negotiating and managing agreements with Medicare Advantage, Medicaid managed care, and commercial health plans that define how a home health agency is paid outside traditional Medicare. A contract sets payment rates and structure, authorization requirements, billing and timely filing rules, and termination provisions. Contract quality directly determines whether non-Medicare census is profitable or a drain.
Medicaid Home Health
Medicaid home health is a mandatory benefit that every state Medicaid program must cover, including part-time nursing, home health aide services, and medical supplies and equipment, with therapies as a common optional addition. Unlike Medicare home health, Medicaid home health cannot be restricted to homebound beneficiaries, and payment is typically per-visit fee-for-service or negotiated managed care rates rather than 30-day episodes.
Medical Social Worker (MSW)
A medical social worker (MSW) in home health addresses social and emotional problems that are expected to impede the patient's medical treatment or rate of recovery, such as unsafe living situations, caregiver breakdown, financial barriers to medications, or the need for community resources and long-term care planning. Under Medicare, MSW is a dependent service: it is covered only when the patient is also receiving a qualifying skilled service.
Medicare Advantage in Home Health
Medicare Advantage (MA), also called Medicare Part C, is the program in which private health plans contract with Medicare to deliver Part A and B benefits, including home health. For agencies, MA means negotiated payment rates, prior authorization requirements, and plan-specific billing rules in place of the uniform fee-for-service system. With more than half of Medicare beneficiaries enrolled in MA plans, managing these contracts well has become core to agency economics.
Medicare Fee-for-Service
Medicare fee-for-service (FFS), also called Original Medicare or traditional Medicare, is the arrangement in which the federal government pays providers directly for covered services under Parts A and B. For home health agencies, FFS patients are paid under the Home Health Prospective Payment System using PDGM, with claims processed by Medicare Administrative Contractors. FFS is the reference payer against which agencies compare every other contract.
Medicare Home Health Benefit
The Medicare home health benefit covers intermittent skilled care delivered in a beneficiary's home by a Medicare-certified home health agency. Eligible patients pay nothing out of pocket for covered home health services, and Medicare pays the agency directly, currently under the Patient-Driven Groupings Model. Eligibility rests on homebound status, a skilled need, a plan of care, a face-to-face encounter, and certification by an allowed practitioner.
Medication Management
Medication management is the ongoing clinical work of reviewing, reconciling, teaching, and monitoring a patient's medications across a home health episode. It is one of the highest-leverage activities in home care because medication problems drive a large share of avoidable emergency visits and rehospitalizations among home health patients.
Medication Reconciliation
Medication reconciliation is the process of comparing the medications a patient is actually taking against what is documented across sources, such as hospital discharge lists, practitioner orders, and pill bottles in the home, then resolving discrepancies. In home health it happens at start of care, after inpatient stays, and whenever orders change, and it is one of the highest-yield safety activities in the setting.
Missed Visit
A missed visit is a visit ordered on the home health plan of care that was not delivered as scheduled, whether because the patient refused or was unavailable, the agency could not staff it, or the visit could not safely occur. Because Medicare requires care to follow the ordered frequency, every missed visit needs documentation, follow-up, and, per agency policy, practitioner notification, and enough of them can push a 30-day period into LUPA territory.
NOA (Notice of Admission)
The Notice of Admission (NOA) is a one-time submission that tells Medicare a home health admission has begun. It is due within 5 calendar days of the start of care, and a late NOA reduces payment for each day between the start of care and the day the NOA is accepted. The NOA replaced Requests for Anticipated Payment (RAPs) on January 1, 2022.
NOMNC (Notice of Medicare Non-Coverage)
The Notice of Medicare Non-Coverage (NOMNC, Form CMS-10123) is a standardized notice that tells a Medicare patient when all covered home health services will end and explains the right to a fast appeal through a Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO). Agencies must deliver it at least two calendar days before covered services end, and the requirement applies to both original Medicare and Medicare Advantage patients.
Non-Admit
A non-admit is a referral that a home health agency receives and processes but never converts into an admitted patient with a completed start of care visit. Non-admits consume intake labor without producing revenue, and their reason codes are one of the most useful diagnostics an agency has for fixing its referral funnel.
NPI (National Provider Identifier)
An NPI (National Provider Identifier) is a unique 10-digit number that identifies a health care provider in standard transactions, required under HIPAA and issued through the National Plan and Provider Enumeration System (NPPES). In home health, NPIs identify the billing agency and the certifying and attending practitioners on claims, orders, and the plan of care.
OASIS
OASIS (Outcome and Assessment Information Set) is the standardized patient assessment data set that Medicare-certified home health agencies must collect for adult Medicare and Medicaid patients receiving skilled care. Completed at defined time points across the episode, OASIS data drives payment under PDGM, quality measures, star ratings, and value-based purchasing adjustments. The current version is OASIS-E2, effective April 1, 2026.
OASIS Accuracy
OASIS accuracy is the degree to which OASIS responses reflect the patient's true status, assessed and coded according to CMS conventions. Because OASIS feeds PDGM payment, outcome measures, star ratings, HHVBP adjustments, and risk adjustment simultaneously, accuracy is the single control point where clinical documentation, revenue integrity, and quality performance converge.
OASIS Submission
OASIS submission is the electronic transmission of completed OASIS assessments to CMS through iQIES, the internet Quality Improvement and Evaluation System. Assessments must be submitted within 30 days of the assessment completion date, and timely, accepted submissions are a Condition of Participation, a quality reporting requirement, and a practical prerequisite for clean billing.
OASIS-E1
OASIS-E1 was the version of the Outcome and Assessment Information Set in effect from January 1, 2025 through March 31, 2026. It was a limited maintenance update to OASIS-E that added the COVID-19 vaccination item O0350 and retired items that had not been used for payment since PDGM began. OASIS-E2 replaced it on April 1, 2026.
OASIS-E2
OASIS-E2 is the current version of the Outcome and Assessment Information Set, effective for home health assessments completed on or after April 1, 2026. It replaced OASIS-E1 with a short list of item changes: M0069 (Gender) was replaced by A0810 (Sex), the A1250 transportation item was replaced by A1255, and the COVID-19 vaccination item O0350 was removed.
OBQI (Outcome-Based Quality Improvement)
OBQI (Outcome-Based Quality Improvement) is a CMS framework in which home health agencies use risk-adjusted, OASIS-based outcome reports to identify weak outcomes, investigate the care processes behind them, and implement a targeted plan of action. It pairs with OBQM (Outcome-Based Quality Monitoring), which tracks adverse events, and its logic underpins modern QAPI programs and value-based purchasing preparation.
Occupational Therapy in Home Health
Occupational therapy (OT) in home health helps patients regain the ability to perform activities of daily living (ADLs) such as bathing, dressing, and toileting, along with instrumental activities like meal preparation and medication management. Under Medicare, OT is not a qualifying service at admission, but a continuing OT need can sustain eligibility after the qualifying services end.
OIG Exclusion List
The OIG exclusion list, formally the List of Excluded Individuals/Entities (LEIE), is the HHS Office of Inspector General's database of people and entities barred from participating in federal health care programs. Medicare and Medicaid will not pay for items or services furnished, ordered, or prescribed by an excluded party, so home health agencies must screen employees, contractors, and vendors against the list and act immediately on matches.
On-Call Coverage
On-call coverage is the system that keeps a home health agency clinically reachable outside business hours, typically a nurse who can triage patient calls and make urgent visits nights, weekends, and holidays. Around-the-clock availability is a baseline expectation for Medicare-certified agencies and a practical necessity for keeping patients out of the emergency department. How on-call is staffed and paid has an outsized effect on clinician retention.
Outcome Measures
Outcome measures capture how a patient's health status changed over the course of home health care, typically between start of care and discharge. In home health they are calculated from OASIS assessments or Medicare claims, risk-adjusted for patient characteristics, and used in public reporting on Care Compare, star ratings, and the Home Health Value-Based Purchasing model.
Outlier Payment
An outlier payment is an additional Medicare payment for a 30-day home health period whose estimated cost of care substantially exceeds its case-mix payment. It exists to protect agencies against outsized losses on unusually resource-intensive patients, and it is subject to both a national spending target and a per-agency cap.
PACE (Program of All-Inclusive Care for the Elderly)
The Program of All-Inclusive Care for the Elderly (PACE) is a capitated Medicare and Medicaid program that provides complete medical and social care to adults 55 and older who meet a nursing facility level of care but can live safely in the community. A PACE organization takes full financial risk and delivers care through an interdisciplinary team, typically anchored to an adult day health center. For home health agencies, PACE is both a competitor for frail seniors and a potential contracting partner.
Pain Assessment
Pain assessment is the structured evaluation of a patient's pain and its impact on sleep, activity, and function. In home health it is a required element of the comprehensive assessment and a recurring part of every skilled visit, and OASIS-E captures it through a standardized patient interview rather than a simple severity score.
Palliative Care
Palliative care is specialized medical care focused on relieving symptoms, pain, and stress for people with serious illness, at any stage and alongside curative treatment. Unlike hospice, it has no prognosis requirement and no requirement to forgo disease-directed therapy. For home health agencies, community-based palliative care is both a valuable clinical partner and an increasingly common adjacent service line.
Patient Engagement
Patient engagement is the degree to which patients understand, participate in, and act on their own care plan. In home health, where clinicians are present a few hours a week at most, engagement is not a soft skill but the delivery mechanism: most of what determines the outcome happens when no clinician is in the home.
Patient Rights in Home Health
Patient rights in home health are the protections guaranteed to every patient under the Medicare Conditions of Participation at 42 CFR 484.50. Agencies must inform patients of these rights verbally and in writing before care begins, honor them throughout the episode, and investigate complaints. Surveyors test compliance through record review and direct patient interviews.
Patient Safety Events
Patient safety events are incidents during care that result in harm to a patient or create a meaningful risk of harm, such as falls with injury, medication errors, pressure injuries, and infections. In home health, these events happen in an uncontrolled environment the agency visits intermittently, which makes systematic identification, reporting, and follow-up harder and more important than in facility settings.
Patient Survey Star Rating
The Patient Survey Star Rating is a 1 to 5 star score on Care Compare that summarizes a home health agency's performance on the HHCAHPS patient experience survey. CMS publishes star ratings for key survey measures plus a summary rating, giving referral sources and families a quick read on how patients rate the agency's care.
Pay-Per-Visit vs. Salary Models
Pay-per-visit and salary are the two dominant compensation structures for home health field clinicians. Pay-per-visit ties earnings directly to completed visits, while salary provides stable income paired with productivity expectations. The choice shapes recruiting, retention, cost structure, and how clinicians experience census swings, and many agencies land on a hybrid of the two.
Payer Mix
Payer mix is the distribution of an agency's patients and revenue across payer types: traditional Medicare fee-for-service, Medicare Advantage, Medicaid, commercial insurance, and private pay. Because reimbursement per episode varies dramatically by payer while the cost of delivering a visit does not, payer mix is one of the strongest predictors of an agency's margin and a lever leadership can manage deliberately rather than inherit by accident.
PDGM (Patient-Driven Groupings Model)
The Patient-Driven Groupings Model (PDGM) is the Medicare payment system for home health, in effect since January 1, 2020. It pays agencies a case-mix adjusted rate for each 30-day period of care, placing every period into one of 432 payment groups based on patient characteristics rather than the volume of therapy visits delivered.
PDGM Analytics
PDGM analytics is the use of data and reporting to manage agency performance under the Patient-Driven Groupings Model (PDGM), Medicare's home health payment system of 30-day periods and 432 case-mix groups. It connects clinical and operational decisions, such as coding accuracy, OASIS scoring, and visit scheduling, to their payment and margin consequences at the period level.
PECOS
PECOS (Provider Enrollment, Chain, and Ownership System) is the online system CMS uses to manage Medicare provider and supplier enrollment. Home health agencies use PECOS to enroll, revalidate, and report changes such as ownership or new locations, and Medicare uses it to verify that the practitioner certifying home health services is eligible to do so. Claims can deny when the certifying practitioner is not properly enrolled.
PEP (Partial Episode Payment)
A Partial Episode Payment (PEP) adjustment prorates a 30-day payment period when the period ends early because the patient transferred to another home health agency, or was discharged with goals met and then readmitted to home health, within the same 30 days. The agency is paid for the portion of the period it was responsible for rather than the full case-mix amount.
Per-Visit Pay
Per-visit pay is a compensation model in which home health field clinicians earn a set rate for each completed visit rather than an hourly wage or salary. Rates are tiered by discipline and visit type, with comprehensive assessment visits such as start of care paying more than routine visits. It is the dominant pay model for field staff at many agencies because it ties labor cost directly to visit volume.
Per-Visit Rate
A per-visit rate is a payment amount tied to each individual home health visit, usually set separately by discipline such as skilled nursing, physical therapy, or aide services. Medicare uses national per-visit rates to pay LUPA periods, and per-visit payment is the most common structure in Medicare Advantage and Medicaid managed care contracts. Under per-visit payment, revenue scales directly with the number of visits delivered.
Personal Care Services
Personal care services (PCS) are non-medical, hands-on assistance with activities of daily living such as bathing, dressing, toileting, transfers, and meal preparation, delivered by aides or personal care attendants. They are funded primarily by Medicaid state plans and HCBS waivers, private pay, and long-term care insurance. Traditional Medicare does not cover standalone personal care, which makes PCS the biggest coverage gap conversation in home health intake.
PHQ-2 and PHQ-9 in Home Health
The PHQ-2 and PHQ-9 (Patient Health Questionnaire) are standardized depression screening instruments embedded in OASIS Section D as the Patient Mood Interview (D0150). The two-question PHQ-2 acts as a gateway: patients who screen positive on the first two questions continue through the full nine-question PHQ-9, producing a severity score (D0160) that informs care planning and referrals.
Physical Therapy in Home Health
Physical therapy (PT) in home health addresses mobility, strength, balance, transfers, and gait so patients can function safely at home. PT is one of the three qualifying services under the Medicare home health benefit, meaning a documented skilled PT need can establish eligibility even when no nursing is ordered.
Physician Certification
Physician certification is the attestation by a physician or allowed practitioner that a patient meets Medicare's home health eligibility requirements at the start of care. It is a condition of payment: the certification must cover five specific elements and be signed and dated before the agency bills the final claim for the first 30-day payment period. Since the CARES Act of 2020, nurse practitioners, physician assistants, and clinical nurse specialists can certify in addition to physicians.
Physician Liaison
A physician liaison is a home health agency representative who builds referral relationships with physicians and their practice staff. Where hospital referrals are competitive and transactional, physician referrals are loyalty-driven, and the liaison's job is to earn that loyalty by making home health ordering effortless and by proving the agency takes good care of the physician's patients.
Physician Order Management
Physician order management is the process and tooling for creating, sending, tracking, and retrieving signed physician orders across a home health episode, including the plan of care and all interim orders. It is one of the highest-stakes administrative workflows in home health because Medicare final claims cannot be billed until orders are signed, making unsigned orders a direct cash flow blocker.
Physician Recertification
Physician recertification is the attestation by the certifying physician or allowed practitioner, required at least every 60 days, that the patient continues to meet Medicare home health eligibility: homebound status, skilled need, and care under a reviewed plan of care. Unlike the initial certification, recertification does not require a new face-to-face encounter, but it must include the practitioner's estimate of how much longer skilled services will be required.
Plan of Care (CMS-485)
The plan of care is the individualized, practitioner-signed document that authorizes and directs every service a home health agency delivers to a patient. Required by both the Conditions of Participation (42 CFR 484.60) and Medicare coverage rules, it specifies diagnoses, services, visit frequencies, medications, goals, and safety measures. The industry still calls it the 485 after the retired CMS-485 form, and it must be reviewed and signed by the physician or allowed practitioner at least every 60 days.
Plan of Correction
A plan of correction (PoC) is the written response a home health agency must submit after a survey identifies deficiencies on the Statement of Deficiencies, Form CMS-2567. It describes how each deficiency will be corrected, how the agency will prevent recurrence, who is responsible, and by what date. The PoC is generally due within 10 calendar days of receiving the 2567, and an accepted PoC is required to stay on track with Medicare participation.
Point-of-Care Documentation
Point-of-care documentation is the practice of completing clinical documentation, including visit notes, OASIS items, and medication updates, in the patient's home during or immediately after the visit. It contrasts with batch charting, where clinicians finish notes at night or days later from memory, and it is one of the strongest predictors of documentation accuracy and clinician satisfaction in home health.
Potentially Preventable Hospitalization
Potentially Preventable Hospitalization (PPH) is a claims-based, risk-adjusted home health quality measure that counts inpatient admissions and observation stays occurring during a home health stay that are classified as potentially preventable. It replaced the all-cause acute care hospitalization and emergency department use measures in CMS home health quality programs, including the expanded HHVBP model beginning with the CY2025 performance year.
Pre-Claim Review
Pre-claim review is a Medicare process in which a home health agency submits the documentation supporting a claim to the review contractor before the final claim is billed, rather than after. Affirmed requests receive a Unique Tracking Number (UTN) that goes on the claim, which then pays without further medical review of those services. It is the flagship option under the Review Choice Demonstration (RCD) in six states.
Predictive Analytics in Home Health
Predictive analytics in home health uses historical and real-time data, including OASIS responses, diagnoses, visit patterns, and vital signs, to forecast events before they happen: hospitalizations, LUPA periods, missed visits, and staffing shortfalls. The value comes not from the prediction itself but from the intervention the prediction triggers.
Preferred Provider Network
A preferred provider network is a curated list of post-acute providers, including home health agencies, that a hospital system, ACO, or payer steers patients toward based on quality, cost, and reliability data. Getting into these networks, and staying in them, has become one of the highest-leverage growth moves available to a home health agency.
Primary Diagnosis
The primary diagnosis is the ICD-10 code representing the condition most related to the patient's current home health plan of care, reported in OASIS item M1021 and as the principal diagnosis on the claim. Under PDGM, it assigns the 30-day period to one of 12 clinical groupings, making it one of the highest-leverage data points in the entire episode.
Private Duty Nursing
Private duty nursing (PDN) is continuous, shift-based skilled nursing delivered in the home, typically in blocks of 4 to 24 hours, for patients who need ongoing licensed nursing care. It is paid hourly by Medicaid programs, some commercial insurance, workers' compensation, or families directly. It is a fundamentally different service from Medicare home health, which covers only intermittent skilled visits.
PRN Visit
A PRN visit (from pro re nata, as needed) is a home health visit made outside the regular ordered frequency in response to a defined patient need, such as a wound dressing that becomes saturated or a catheter that stops draining. Medicare covers PRN visits only when the plan of care order specifies the medical criteria that justify the visit and states a specific maximum number of PRN visits, so open-ended "as needed" orders are not billable orders.
Process Measures
Process measures assess whether a home health agency performed specific evidence-based care practices, regardless of how the patient's condition ultimately changed. The flagship example in home health is Timely Initiation of Care, which measures whether care started within the required window after referral or hospital discharge.
Productivity Standards
Productivity standards define the expected visit output for full-time home health clinicians, usually expressed as weighted points per day or week. Visit types carry different weights so that a start of care with its OASIS assessment counts more than a routine visit. Staffing plans, capacity, and cost per visit all flow from these standards, which makes them one of the most consequential numbers an agency sets.
Public Reporting
Public reporting is the CMS practice of publishing home health agency quality data for anyone to see, primarily through the Care Compare website. Published data includes star ratings, OASIS-based outcome measures, claims-based measures, and HHCAHPS patient survey results. Because referral sources, health systems, and patients all consult this data, public reporting turns quality performance into a marketing asset or a liability.
QAPI (Quality Assurance and Performance Improvement)
Quality Assurance and Performance Improvement (QAPI) is the agency-wide, data-driven quality program required of every Medicare-certified home health agency by the Condition of Participation at 42 CFR 484.65. A compliant QAPI program continuously collects and analyzes quality data, acts on the findings through performance improvement projects, and shows measurable results, with the governing body accountable for the whole cycle.
Quality of Patient Care Star Rating
The Quality of Patient Care Star Rating is a 1 to 5 star summary score, in half-star increments, that CMS publishes for each home health agency on Care Compare. It condenses a defined set of OASIS-based and claims-based quality measures into a single consumer-facing rating, updated quarterly.
RAP (Request for Anticipated Payment)
A Request for Anticipated Payment (RAP) was the claim a home health agency filed at the start of each payment period to receive an upfront portion of the expected Medicare payment. RAP payments were phased down to zero in 2021, and the RAP itself was eliminated and replaced by the Notice of Admission (NOA) on January 1, 2022. The term now matters mainly as historical context.
RCD (Review Choice Demonstration)
The Review Choice Demonstration (RCD) is a CMS program that requires Medicare home health agencies in participating states to have essentially all claims reviewed, letting each agency choose how: pre-claim review before final billing, postpayment review after payment, or reduced-review options earned through good performance. RCD currently operates in Illinois, Ohio, Texas, North Carolina, Florida, and Oklahoma, and CMS extended it for five more years effective June 1, 2024.
Real-Time Eligibility
Real-time eligibility is the electronic verification of a patient's insurance coverage in seconds rather than by phone or portal lookup, typically through the X12 270/271 transaction standard. For Medicare patients, agencies query the HIPAA Eligibility Transaction System (HETS) directly or through their EHR or a clearinghouse, confirming coverage details before committing to an admission.
Recertification Assessment
The recertification assessment is the follow-up OASIS completed during the last 5 days of each 60-day certification period, days 56 through 60, when the patient will continue home health care into a new period. It updates the comprehensive assessment, supports the practitioner's recertification of eligibility, and informs the plan of care for the next 60 days.
Recruiting in Home Health
Recruiting in home health is the process of sourcing, hiring, and onboarding nurses, therapists, aides, and support staff for a field-based care model. Because agency capacity is capped by field clinicians, recruiting is effectively growth strategy: an agency cannot accept referrals it cannot staff. Home health competes for the same clinical labor pool as hospitals, facilities, and staffing firms, usually without matching their pay scales, so it wins on flexibility, autonomy, and working conditions.
Referral Source
A referral source is any person, organization, or platform that sends patients to a home health agency, such as a hospital discharge planner, physician practice, skilled nursing facility, or accountable care organization. Tracking referral sources shows an agency where its census actually comes from, which relationships deserve investment, and where growth is at risk.
Referral-to-SOC Conversion Rate
Referral-to-SOC conversion rate is the percentage of referrals an agency receives that become admitted patients with a completed start of care (SOC) visit. It is the core intake metric: it tells you how much of the demand you generate actually turns into census and revenue, and where referrals leak out of the funnel.
Rehospitalization Reduction
Rehospitalization reduction is the systematic effort to keep home health patients from returning to the hospital during or shortly after their episode of care. It sits at the center of home health quality strategy because hospitalization outcomes drive HHVBP payment adjustments, star ratings, and the referral decisions of hospitals, ACOs, and Medicare Advantage plans.
Remote Patient Monitoring (RPM)
Remote patient monitoring (RPM) is the use of connected devices, such as blood pressure cuffs, scales, pulse oximeters, and glucometers, to collect patient health data between visits and transmit it to the care team for review. In home health, RPM extends surveillance of high-risk patients beyond the two or three visits a week a clinician can physically make.
Resumption of Care (ROC)
Resumption of Care (ROC) is the OASIS time point completed when a patient returns to home health services after an inpatient facility stay of 24 hours or more for reasons other than diagnostic tests. The ROC assessment must be completed within 2 calendar days of the patient's return home or the agency's knowledge of the return, and it reestablishes the clinical baseline after the hospitalization.
Revenue Codes in Home Health
Revenue codes are the four-digit codes on institutional claims that categorize each line item by the type of service provided. On a Medicare home health claim, they identify each visit line by discipline, mark supply lines, and flag the special 0023 line that carries the HIPPS code for the payment period.
Revenue Cycle Management (RCM)
Revenue cycle management (RCM) is the end-to-end process of converting care delivered into cash collected: referral intake, eligibility verification, authorization, clinical documentation and coding, claim submission, payment posting, denials and appeals, and reporting. In home health, RCM is unusually front-loaded, because most payment failures trace back to intake, eligibility, and clinical documentation rather than to the billing office.
Risk Adjustment
Risk adjustment is the statistical method CMS uses to account for differences in patient characteristics when calculating home health outcome measures. Using OASIS and claims data, models predict each patient's expected outcome given their condition, and agencies are evaluated on observed performance relative to expected, so an agency serving sicker, more complex patients is not automatically penalized.
Scheduling and Routing
Scheduling and routing is the daily operational work of assigning home health visits to clinicians and sequencing them geographically. Every schedule must satisfy ordered visit frequencies, assessment windows, patient availability, clinician skills, and drive-time reality at the same time. It is where an agency's clinical plans meet its labor capacity, and scheduling failures surface as missed visits, compliance findings, and unbillable windshield time.
Secondary Diagnosis
Secondary diagnoses are the additional confirmed conditions, reported in OASIS item M1023 and on the claim, that coexist with the primary diagnosis and affect the patient's care. Under PDGM they determine the comorbidity adjustment, which can raise the 30-day period's case-mix weight when qualifying conditions or interacting condition pairs are present.
Section GG Self-Care and Mobility
Section GG self-care and mobility refers to the two core item sets within OASIS Section GG: GG0130, which scores self-care activities such as eating, oral hygiene, bathing, and dressing, and GG0170, which scores mobility activities from rolling in bed through walking distances and negotiating steps. Together they produce the standardized functional profile used in home health quality measurement.
Sequential Billing
Sequential billing is the Medicare requirement that home health claims for an admission process in chronological order: the Notice of Admission first, then each 30-day period claim in date sequence. A claim cannot finalize until the claims ahead of it have processed, which makes one stuck claim a cash-flow problem for the entire admission.
Skilled Need
Skilled need is the Medicare home health eligibility requirement that the patient needs reasonable and necessary skilled services: intermittent skilled nursing care, physical therapy, speech-language pathology services, or a continuing need for occupational therapy. A service is skilled when its inherent complexity requires the judgment of a nurse or therapist to be performed safely and effectively, and the need must be documented, not assumed from a diagnosis.
Skilled Nursing
Skilled nursing is care that can only be safely and effectively performed by a licensed nurse, either a registered nurse (RN) or a licensed practical nurse (LPN) under RN supervision. In Medicare home health, intermittent skilled nursing is one of the qualifying services that establishes eligibility for the benefit, and every skilled nursing service must be ordered on the plan of care by the certifying practitioner.
Skilled Nursing Facility (SNF)
A skilled nursing facility (SNF) provides short-term skilled nursing and rehabilitation in an institutional setting, typically after a hospital stay, under the Medicare Part A SNF benefit. For home health agencies, SNFs are simultaneously an upstream referral source, a downstream discharge destination, and the setting home health increasingly competes against for post-acute referrals.
Skilled Observation and Assessment
Skilled observation and assessment is a Medicare coverage category for skilled nursing: visits are covered when the patient's condition creates a reasonable likelihood of change or complication that requires a nurse to evaluate the need for modified treatment or additional medical intervention. It is the coverage basis for many post-hospital and exacerbation-driven episodes, and it is also one of the most commonly denied categories when documentation shows a stable patient.
SNF-at-Home
SNF-at-home is an emerging care model that delivers skilled nursing facility-level post-acute care in a patient's home instead of an institutional setting, bundling intensive nursing, therapy, aide support, equipment, and remote monitoring. Unlike hospital-at-home, it has no dedicated Medicare fee-for-service payment model, so today it lives mostly in Medicare Advantage and risk-based arrangements.
SOC Timeliness
SOC timeliness measures how quickly a home health agency completes the start of care (SOC) visit after receiving a referral or after the patient's hospital discharge. CMS measures it through the Timely Initiation of Care quality measure, which expects care to begin within two days, and referral sources treat it as a core test of agency reliability.
Social Determinants of Health (SDOH)
Social determinants of health (SDOH) are the non-medical conditions that shape health outcomes, such as transportation access, health literacy, social isolation, language, and economic stability. OASIS collects standardized SDOH items, including ethnicity, race, preferred language, transportation (A1255 under OASIS-E2), health literacy, and social isolation, so home health agencies now assess and report these factors, not just notice them.
Speech-Language Pathology in Home Health
Speech-language pathology (SLP) in home health evaluates and treats disorders of swallowing, speech, language, voice, and cognitive-communication, most often after stroke, progressive neurological disease, or head and neck cancer. SLP is one of the three qualifying services under the Medicare home health benefit, so a skilled SLP need can establish eligibility on its own.
Standard-Level Deficiency
A standard-level deficiency is a survey finding that a home health agency failed to meet a specific standard within one of the Medicare Conditions of Participation, while the condition as a whole remains met. It is the most common survey citation and requires a plan of correction, but it does not by itself trigger the termination track that follows a condition-level finding.
Stark Law
The Stark Law, formally the physician self-referral law, is a federal civil statute that prohibits a physician from referring Medicare patients for designated health services, a category that includes home health, to an entity with which the physician or an immediate family member has a financial relationship, unless a specific exception applies. It is a strict liability law: intent does not matter, and a technically noncompliant arrangement is a violation. This page is educational and general, not legal advice.
Start of Care (SOC)
Start of Care (SOC) is the date of the first billable visit in a home health episode, and the name of the OASIS assessment completed at that point. The SOC date anchors nearly every downstream deadline: the comprehensive assessment window, the Notice of Admission, the 60-day certification period, and the first 30-day PDGM payment period.
State Survey
A state survey is an unannounced on-site inspection of a home health agency conducted by the state survey agency acting on behalf of CMS. Surveyors evaluate the agency against the Medicare Conditions of Participation through home visits, clinical record review, and staff interviews. Standard surveys occur at least every 36 months, and complaint surveys can happen at any time.
Supervisory Visit
A supervisory visit is an on-site visit by a registered nurse or appropriate skilled professional to oversee home health aide services and confirm the aide care plan is being followed and still meets the patient's needs. Medicare's Conditions of Participation require these visits at least every 14 days for patients receiving skilled care, and they are among the most frequently cited requirements in home health surveys.
Teaching and Training
Teaching and training is a skilled service category in Medicare home health covering education of the patient, family, or caregiver to manage the patient's care: medications, diabetic self-management, wound dressing technique, ostomy care, disease self-monitoring, and safe equipment use. The teaching itself is skilled because it requires clinical knowledge to deliver, so it is covered even when the task being taught is one a layperson will ultimately perform.
Telehealth in Home Health
Telehealth in home health is the use of telecommunications technology, including real-time audio-video and audio-only interactions, to deliver services under a Medicare home health plan of care. Medicare permits telehealth as a supplement when it is ordered on the plan of care, but telecommunications encounters cannot substitute for ordered in-person visits and do not count as visits for payment purposes.
Territory Management
Territory management is the practice of dividing an agency's service area into geographic zones and assigning clinicians, and often marketers, to each. Because drive time is unbillable, territory design is a core economic decision: it determines how much of each clinician's day produces visits versus windshield time. It also shapes referral coverage, on-call logistics, and the point at which opening a branch makes sense.
Timely Initiation of Care
Timely initiation of care is a home health process measure showing the percentage of episodes in which care began within two days of the referral date, the physician-ordered start date, or the patient's inpatient facility discharge. It is publicly reported on Care Compare and is a component of the Quality of Patient Care Star Rating.
Timing (Early vs. Late Periods)
Timing is the Patient-Driven Groupings Model (PDGM) variable that classifies each 30-day payment period as early or late. The first 30-day period in a sequence of home health care is early, every subsequent adjacent period is late, and early periods carry higher case-mix weights because resource use is typically heaviest at the start of care.
Total Performance Score (TPS)
The Total Performance Score (TPS) is the composite score, on a 0 to 100 scale, that CMS calculates for each home health agency under the expanded Home Health Value-Based Purchasing (HHVBP) model. It combines weighted OASIS-based, claims-based, and HHCAHPS survey measures, and it directly determines the agency's Medicare payment adjustment of up to plus or minus 5%.
TPE (Targeted Probe and Educate)
Targeted Probe and Educate (TPE) is the Medicare Administrative Contractor (MAC) medical review program that examines a sample of 20 to 40 claims per round from providers whose billing looks unusual compared to peers or whose services have high improper payment rates. Providers with high error rates receive one-on-one education and up to two more rounds; those who fail all three rounds can be referred to CMS for stronger action.
Transfer OASIS
A transfer OASIS is the assessment time point completed when a home health patient is admitted to an inpatient facility for 24 hours or more for reasons other than diagnostic tests. It comes in two forms: transfer without agency discharge, when the agency expects the patient back, and transfer with discharge, when the agency ends care. It must be completed within 2 calendar days of the transfer or of learning about it.
Transitional Care
Transitional care is the coordinated set of services that ensures continuity and safety as a patient moves from one care setting to another, most critically from hospital to home. For home health agencies, transitional care is both a clinical discipline and a growth strategy: agencies that demonstrably manage the first weeks after discharge win hospital, ACO, and payer referrals.
Type of Bill 32X
Type of bill (TOB) 32X is the family of type of bill codes that identifies Medicare home health claims for services under a home health plan of care. The first digits mark the claim as home health, and the final character tells the payer what kind of submission it is: a Notice of Admission, an original final claim, an adjustment, or a cancellation.
UPIC Audit
A UPIC audit is an investigation by a Unified Program Integrity Contractor, the CMS contractor charged with detecting and investigating suspected fraud, waste, and abuse in Medicare and Medicaid. Unlike routine medical review, a UPIC audit is triggered by fraud indicators such as data outliers, complaints, or referrals, and can lead to payment suspension, extrapolated overpayment demands, and referral to law enforcement.
Utilization Management
Utilization management (UM) is the set of processes payers and providers use to control how much care is delivered: prior authorization, visit-level approvals, concurrent review, and reauthorization. In home health, UM is mostly felt through Medicare Advantage and Medicaid managed care plans, and it shapes which referrals an agency can profitably accept.
Value-Based Care
Value-based care is the shift from paying for volume of services to paying for outcomes and total cost of care. In home health, the most direct expression is the expanded Home Health Value-Based Purchasing (HHVBP) model, which adjusts Medicare payments up or down based on quality performance. Value-based pressure also reaches agencies through accountable care organizations, Medicare Advantage plans, and bundled payment arrangements.
Verbal Orders
A verbal order is a patient care order that a physician or allowed practitioner communicates orally, usually by phone, to a qualified clinician at the home health agency. The clinician documents the order immediately, and the ordering practitioner must later authenticate it with a dated signature. Unsigned verbal orders are one of the most common causes of delayed final claims and survey citations.
Vital Signs Parameters
Vital signs parameters are the patient-specific thresholds written into the home health plan of care that define when a blood pressure, pulse, temperature, respiratory rate, oxygen saturation, weight, or blood glucose reading requires notifying the ordering practitioner. They turn routine vital sign collection into a monitoring system with defined triggers.
Wound Care in Home Health
Wound care in home health is the skilled assessment and treatment of surgical wounds, pressure injuries, ulcers, and other chronic or complex wounds in the patient's home, including dressing changes, wound measurement and staging, infection surveillance, and caregiver training. It is one of the clearest skilled nursing services under Medicare and maps to a dedicated Wound clinical grouping under PDGM.
