Medicare and Assisted Living: What Is and Is Not Covered

Medicare covers a great deal — hospital stays, physician visits, prescription drugs, short-term rehabilitation — but assisted living sits almost entirely outside its reach. For families navigating how to pay for assisted living, that gap is one of the most consequential financial facts they will encounter. This page explains exactly where Medicare's coverage ends, what limited exceptions exist, and how those boundaries shape real-world decisions.

Definition and scope

Medicare is a federal health insurance program administered by the Centers for Medicare & Medicaid Services (CMS) and covers approximately 65 million Americans as of the program's 2023 enrollment data. It is structured around medical care — diagnosis, treatment, and recovery — not around housing or long-term personal care.

Assisted living, by contrast, is a residential care model built around what Medicare's framework calls "custodial care": help with bathing, dressing, toileting, meals, and medication reminders. CMS explicitly excludes custodial care from Medicare coverage when that care is the primary reason for a facility stay (Medicare.gov: What's Not Covered). The term "custodial" carries significant regulatory weight here. It is the statutory dividing line that determines reimbursement eligibility, and it applies regardless of how frail or medically complex a resident may be.

The regulatory context for assisted living reinforces this divide: assisted living facilities are licensed at the state level — not federally certified as Medicare providers — which means they cannot bill Medicare for the room-and-board component of care under any circumstance.

How it works

Medicare operates in four parts, and understanding each part's scope clarifies where coverage does and does not reach in an assisted living setting.

  1. Part A (Hospital Insurance): Covers inpatient hospital care, skilled nursing facility (SNF) stays following a qualifying 3-day hospital admission, hospice care, and limited home health. It does not cover room and board in an assisted living facility.
  2. Part B (Medical Insurance): Covers physician services, outpatient care, durable medical equipment, and preventive services. A resident of an assisted living facility can use Part B benefits for a physician who visits on-site or for outpatient medical appointments — the coverage travels with the person, not the facility.
  3. Part C (Medicare Advantage): Private plans that deliver Part A and B benefits, sometimes with added benefits such as vision, dental, or transportation. A small number of Medicare Advantage plans have begun offering limited supplemental benefits relevant to assisted living residents, such as meal delivery or personal emergency response devices, under expanded authority granted by CMS beginning in 2019 (CMS Medicare Advantage Final Rule 2019).
  4. Part D (Prescription Drug Coverage): Covers outpatient prescription drugs. This benefit functions normally for assisted living residents, though the facility's medication management practices govern how those drugs are administered internally.

The net result: Medicare may pay for a physician's visit inside an assisted living facility, for a short-term skilled nursing stay at a separate SNF, or for hospice services delivered to a resident in an assisted living setting. It will not pay for the assisted living facility's monthly fee.

Common scenarios

Scenario 1 — Short-term rehabilitation after a hospital stay. A resident is hospitalized for a hip fracture, qualifies for a 3-day inpatient admission, and is then discharged. Medicare Part A can cover up to 100 days in a certified skilled nursing facility for rehabilitation — not in the assisted living facility itself, unless that facility operates a licensed, Medicare-certified SNF unit on the same campus. Days 1–20 are covered at 100%; days 21–100 carry a coinsurance of $194.50 per day in 2024 (CMS Medicare SNF Benefit Policy).

Scenario 2 — Hospice care. Medicare Part A covers hospice for residents of assisted living facilities when a physician certifies a terminal prognosis of 6 months or less. The hospice agency bills Medicare directly for its services; the assisted living facility continues to bill the resident (or other payers) for room and board. The two billing streams run in parallel.

Scenario 3 — Physician and specialist visits. A geriatrician who conducts monthly visits to an assisted living community bills those visits under Part B. The assisted living facility is simply the location — Medicare's relationship is with the physician, not the facility.

Scenario 4 — Dementia care in a memory unit. A resident with moderate Alzheimer's disease living in a memory care within assisted living setting pays the facility's monthly fee entirely from private funds or Medicaid (where applicable). Medicare does not cover that fee regardless of the resident's diagnosis or level of cognitive impairment.

Decision boundaries

The central question families and care coordinators must ask is whether a specific service is medical or custodial in character. Medicare covers the former; it does not cover the latter. That distinction, while conceptually clear, produces edge cases in practice.

Skilled nursing services — wound care, IV therapy, physical therapy delivered by licensed therapists — are medical and can be reimbursed through Medicare when provided by a qualifying agency or facility. Personal care — bathing assistance, meal preparation, reminding a resident to take medication — is custodial, regardless of how frequently it is needed or how medically vulnerable the recipient is.

Medicaid, not Medicare, is the primary public payer for assisted living costs for low-income individuals, and its coverage varies by state through Home and Community-Based Services (HCBS) waivers. The differences between these two programs are significant enough to shape entire financial plans. A thorough overview of the broader landscape of coverage options is available through assistedlivingauthority.com, where the full structure of funding pathways is documented in detail.

Families planning for assisted living costs should confirm which Medicare-covered services — particularly hospice and Part B physician services — can be delivered to a specific facility, since operational agreements between facilities and service providers vary. The assisted living cost breakdown provides further detail on how these funding layers interact with monthly fee structures.
