Home Health Services Coverage Under Medicare and Medicaid

Medicare and Medicaid each provide coverage for home health services under distinct statutory frameworks, eligibility criteria, and benefit structures. Understanding how these two programs define and reimburse home-based clinical care is essential for patients, caregivers, and healthcare administrators navigating post-acute care options after a hospitalization or during the management of a chronic condition. This page outlines the regulatory scope, operational mechanics, covered service categories, and coverage boundaries for home health benefits under both federal programs.

Definition and scope

Home health services, as defined under federal statute, are skilled clinical services delivered in a patient's residence by or under the supervision of licensed healthcare professionals. Under 42 U.S.C. § 1395x(m), the Centers for Medicare & Medicaid Services (CMS) defines home health services to include skilled nursing care, physical therapy, occupational therapy, speech-language pathology services, medical social services, and home health aide services.

The term "homebound" carries specific regulatory weight under Medicare. A beneficiary qualifies as homebound when leaving home requires a considerable and taxing effort, a standard drawn from CMS Medicare Benefit Policy Manual, Chapter 7. Conditions such as stroke-related mobility impairments, post-surgical restrictions, or severe cardiopulmonary disease commonly satisfy this threshold.

Medicaid home health services are governed by 42 C.F.R. Part 440, which requires states to cover certain mandatory home health services for all Medicaid-eligible individuals entitled to nursing facility services. States retain authority to expand coverage through optional benefit categories, including Home and Community-Based Services (HCBS) waivers authorized under Section 1915(c) of the Social Security Act. As of federal reporting, all 50 states and the District of Columbia operate at least one HCBS waiver program (CMS HCBS Overview).

How it works

Medicare home health coverage operates under a prospective payment system administered by CMS. Covered services are delivered through Medicare-certified home health agencies (HHAs). The benefit structure under Medicare Part A and Part B does not impose a copayment for home health services, and there is no prior hospitalization requirement — a common misconception. Certification by a physician or an allowed non-physician practitioner is required before services begin.

The payment model uses the Patient-Driven Groupings Model (PDGM), implemented January 1, 2020 (CMS PDGM Final Rule). Under PDGM, 30-day payment periods replace the previous 60-day episode model, and payment rates are adjusted by clinical grouping, functional impairment level, and comorbidity. The prior authorization process is not federally mandated for standard Medicare home health, though certain high-utilization states operate prior authorization demonstration programs.

Medicaid home health coverage varies by state but must include, at minimum:

  1. Part-time or intermittent nursing services
  2. Home health aide services
  3. Medical supplies, equipment, and appliances suitable for home use
  4. Physical therapy, occupational therapy, or speech pathology when required under a plan of care

States that elect HCBS waivers may also cover personal care assistance, adult day services, respite care, and home modifications. Reimbursement structures differ across states — fee-for-service, managed care, and capitated models are all in use. Medicaid managed care plans contracting with states must cover home health benefits in accordance with the 42 C.F.R. § 438 managed care regulations.

Coordination between Medicare and Medicaid applies to dual-eligible beneficiaries — individuals enrolled in both programs simultaneously. For this population, Medicare pays first for covered home health services, and Medicaid may cover cost-sharing or additional non-Medicare-covered services. The Medicare Savings Programs administered through state Medicaid agencies assist with cost-sharing obligations for qualifying dual-eligibles.

Common scenarios

Three clinical and administrative situations most frequently trigger home health coverage determinations:

Post-acute discharge: A patient discharged from an acute-care hospital following hip replacement surgery requires skilled physical therapy and wound care at home. Medicare covers these services provided the patient meets homebound criteria and a certifying physician documents a plan of care. The durable medical equipment coverage benefit may run concurrently for equipment such as walkers or hospital beds.

Chronic disease management: A patient with congestive heart failure requiring weekly skilled nursing visits for medication management and vital sign monitoring qualifies under Medicare if homebound status is maintained. Long-term chronic care scenarios are also addressed through chronic disease management programs that may overlap with home health coordination.

Medicaid long-term services: An elderly Medicaid beneficiary who does not qualify for Medicare, or who exhausts Medicare-covered episodes, may receive ongoing personal care and home health aide services under a state Medicaid plan or HCBS waiver. This scenario is particularly relevant for individuals below the nursing facility level of care but requiring consistent in-home support — a population served extensively through Section 1915(c) waiver programs.

Decision boundaries

Coverage determinations hinge on several classification distinctions:

Skilled vs. unskilled care: Medicare covers only skilled services — those requiring the professional judgment of a licensed nurse, therapist, or other qualified clinician. Custodial care, defined as assistance with activities of daily living (ADLs) such as bathing, dressing, and meal preparation, is excluded from Medicare home health benefits unless provided incidentally to a skilled service. Medicaid, through HCBS waivers, explicitly covers personal care and custodial services that Medicare does not reach.

Intermittent vs. continuous care: Medicare home health covers part-time or intermittent skilled nursing, defined under 42 C.F.R. § 409.44 as less than 8 hours per day and 28 or fewer hours per week, with exceptions up to 35 hours per week for medically predictable needs. Continuous, around-the-clock nursing — such as that required for ventilator-dependent patients — falls outside standard Medicare home health and may require private-duty nursing coverage or hospice enrollment. For end-of-life scenarios, hospice and palliative care services represent a separate Medicare benefit entirely.

Agency certification status: Home health agencies must maintain Medicare certification through CMS and meet Conditions of Participation outlined in 42 C.F.R. Part 484. Services delivered by non-certified agencies are not reimbursable under Medicare, regardless of clinical appropriateness. State Medicaid programs maintain parallel enrollment and certification requirements for participating HHAs.

Coverage interaction with managed care: Beneficiaries enrolled in Medicare Advantage (Part C) plans receive home health benefits through their plan rather than original Medicare fee-for-service. Plan-specific authorization requirements, network restrictions, and benefit structures may differ materially from those of original Medicare — a distinction outlined in the Medicare Parts A, B, C, D Explained reference. Similarly, Medicaid managed care enrollees access home health through contracted plans subject to state-specific benefit designs and prior authorization protocols.

Disputes over home health coverage eligibility and service duration may be addressed through the Medicare appeals process or, for Medicaid beneficiaries, through state fair hearing procedures. The healthcare complaint and grievance process outlines the procedural pathways available under federal and state frameworks.
