Referrals & Growth
Reviewed by Zach Newman · Last reviewed July 2026
Census growth in home health starts at the referral. Discharge planners, physician liaisons, and ACOs decide where patients go, and the agencies that convert referrals to Start of Care fastest tend to win the relationship. This glossary of home health referral terms defines the language of intake and growth, from referral source and payer mix to the referral-to-SOC conversion rate and care transitions.
22 termsACO (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.
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.
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
