Technology & Data

The tools an agency runs on now decide how much time clinicians spend charting instead of caring. Point-of-care documentation, real-time eligibility, predictive analytics, and AI are changing what a home health EHR is expected to do. This glossary of home health technology terms defines the systems and data language behind modern agencies, from interoperability and clinical decision support to documentation burden and remote patient monitoring.
15 termsAI 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
