Home Health Services: Eligibility, Providers, and Coverage
Home health services bring skilled medical and supportive care directly into a patient's living space — an arrangement that shifts the clinical encounter from a hospital corridor to a kitchen table. This page covers who qualifies for home health care under federal programs, which types of providers deliver it, and how Medicare, Medicaid, and private insurance each handle coverage. The distinctions matter because a misread eligibility rule can mean the difference between fully covered skilled nursing visits and an unexpected out-of-pocket bill.
Definition and scope
Home health care is a formally defined category under federal law. Medicare, the largest single payer of home health services in the United States, defines it as part-time or intermittent skilled nursing care, physical therapy, occupational therapy, speech-language pathology, medical social services, and home health aide services — all furnished in a patient's place of residence (Medicare Benefit Policy Manual, Chapter 7).
The word "residence" does more work than it looks like. The Centers for Medicare & Medicaid Services (CMS) considers a patient's home to include a private dwelling, a relative's home, an assisted living facility, or certain group home settings — but not a hospital, skilled nursing facility, or most long-term care institutions. That boundary shapes eligibility for millions of older adults navigating the overlap between long-term care options and acute recovery.
Home health is also distinct from home care. Home care — sometimes called custodial care — covers non-medical support like bathing assistance, meal preparation, and housekeeping. Medicare does not cover custodial care when that is the only service needed. The line between skilled and custodial is where most coverage disputes originate.
How it works
A physician, nurse practitioner, clinical nurse specialist, or certified nurse midwife must certify that a patient is homebound and requires one of the qualifying skilled services. "Homebound" under CMS criteria means leaving home requires a considerable and taxing effort — the standard explicitly accommodates patients who can attend medical appointments without losing their homebound status, a nuance that surprises many families.
Once certified, a Medicare-certified home health agency (HHA) takes over coordination. As of the CMS data published for the 2023 payment year, there were approximately 11,500 Medicare-certified HHAs operating across the United States (CMS Home Health Agency Center). These agencies are subject to Conditions of Participation set in 42 CFR Part 484, which govern staffing, patient rights, and care planning requirements.
Under Medicare Part A or Part B (home health straddles both, depending on circumstances), covered visits have no deductible and no coinsurance — with one notable exception: durable medical equipment supplied through the home health benefit carries a 20% coinsurance.
The payment model shifted in January 2020 to the Patient-Driven Groupings Model (PDGM), which classifies patients into one of 432 payment groups based on clinical characteristics and functional status rather than the volume of therapy visits. That change structurally reduced the incentive agencies had to inflate therapy utilization.
Common scenarios
Three situations account for the majority of home health referrals:
- Post-acute recovery — A patient discharged after a hip replacement or cardiac event requires skilled nursing to manage wound care, medication titration, or IV therapy at home before transitioning to independent management.
- Chronic disease stabilization — A patient with congestive heart failure or chronic disease management needs periodic skilled nursing visits to monitor fluid status and prevent rehospitalization.
- Functional rehabilitation — Physical or occupational therapy delivered at home helps patients regain mobility and adapt their living environment after a stroke or serious fall.
A fourth scenario worth naming: patients receiving palliative and hospice care who are not yet on the Medicare hospice benefit may access home health as a bridge — receiving skilled pain management visits while still pursuing curative treatment.
Decision boundaries
The clearest way to map coverage is by payer:
Medicare covers home health with no cost-sharing (except DME) when the homebound and skilled-care criteria are met. There is no prior hospital stay requirement — a persistent misconception. The benefit is technically unlimited in duration, but each 60-day episode must be recertified by an eligible clinician.
Medicaid coverage varies by state. Federal law requires states to cover home health for Medicaid beneficiaries who would qualify for institutional care, but the scope of optional home- and community-based services differs sharply across state programs. California's Medi-Cal, for example, covers a broader set of in-home supportive services than what is strictly required under federal baseline rules. Families navigating this landscape benefit from reviewing the Medicaid overview and understanding their state's specific waiver programs.
Private insurance plans governed by the Affordable Care Act are not required to cover home health as an essential health benefit in the same way Medicare defines it — coverage terms, visit caps, and prior authorization requirements vary by plan and state mandate. The understanding health insurance framework helps clarify how to read plan documents for these specifics.
Medicare Advantage plans must cover everything original Medicare covers, but they may impose prior authorization requirements and use their own network of preferred HHAs. A patient's preferred agency may not be in-network, which affects cost even when the underlying service is covered.
One final boundary worth stating plainly: home health and hospice cannot be billed simultaneously under the Medicare hospice benefit for the same terminal condition. If a hospice patient needs skilled nursing for an unrelated condition, a separate home health claim is technically possible — but the administrative and clinical documentation burden is significant, and healthcare costs and billing complexity rises accordingly.
