Medicare covers some nursing home costs for dementia, but only under specific conditions — and most dementia care is not covered at all

Medicare will pay for a nursing home stay only if you are admitted directly from a hospital after a three-day inpatient stay, and only if the care you need is skilled nursing care — meaning medical services like wound care, IV therapy, or physical therapy ordered by a doctor. Custodial care, which is what most dementia residents receive (help with bathing, dressing, eating, and supervision), is not covered by Medicare under any circumstance. If you enter a nursing home for dementia without a hospital stay first, Medicare pays nothing.

This distinction matters because dementia itself is not a skilled nursing condition in Medicare's view. A person with dementia who needs only supervision and personal care will not may have access to for Medicare coverage, even if they live in a nursing home. Medicare will cover the skilled services — like managing diabetes medication or treating a urinary tract infection — but not the dementia care itself.

The coverage that does exist is also temporary. Medicare pays for up to 100 days in a nursing home per benefit period, with your costs changing at day 21. Days 1 through 20 are fully covered. Days 21 through 100 require a daily copay (the amount changes yearly). After 100 days, you pay all costs yourself.

Key Takeaways

  • Medicare covers nursing home care only if you spent at least three days in a hospital first, and only for skilled nursing services, not dementia supervision or personal care.
  • Dementia care alone — bathing, dressing, eating information, and monitoring — is custodial care and is never covered by Medicare.
  • If Medicare does cover your stay, it pays in full for the first 20 days, then requires a daily copay for days 21 through 100, after which you pay everything.
  • Medicaid, not Medicare, is the program that typically pays for long-term dementia care in a nursing home, and coverage depends on your income and assets.

When Medicare will and will not pay for nursing home care

Medicare coverage of nursing home care depends on two things happening in this exact order: a hospital stay of at least three consecutive days, followed by admission to a nursing home for continued skilled care. The hospital stay must be for the same condition (or a related one) that requires the nursing home care. A three-day stay for pneumonia followed by admission for dementia supervision does not trigger coverage.

The skilled care requirement is the second gate. Medicare defines skilled nursing care as services that must be performed or supervised by a nurse or therapist — things like managing a catheter, administering injections, wound dressing, physical therapy, or speech therapy. If your doctor orders these services and you receive them in the nursing home, Medicare may cover the cost. If you are in the nursing home only because you have dementia and need help with daily activities, Medicare does not pay.

Many people with dementia do have skilled care needs — managing medications for other conditions, treating infections, or recovering from a fall. In those cases, Medicare can cover the nursing home stay while those skilled services are being provided. But once the skilled need ends, Medicare coverage ends, even if you remain in the nursing home.

How much Medicare pays and for how long

Medicare's nursing home benefit is measured in days per benefit period, not dollars. A benefit period begins the day you enter the hospital and ends 60 days after you leave the hospital or nursing home, whichever is later. If you are readmitted to a hospital more than 60 days later, a new benefit period starts.

Within each benefit period, Medicare covers up to 100 days of nursing home care. The payment structure changes at day 21. Days 1 through 20 are covered at 100 percent — you pay nothing (except your Part A deductible, which applies to the hospital stay, not the nursing home). Starting on day 21, you pay a daily copay amount set by Medicare each year. This copay applies to days 21 through 100. After day 100, Medicare pays nothing, and you are responsible for all costs.

The daily copay for days 21 through 100 is substantial — in 2024 it is $200 per day, though this amount changes yearly. For a 30-day stay, you would pay nothing. For a 50-day stay, you would pay the copay for 30 days (days 21 through 50). For a 100-day stay, you would pay the copay for 80 days (days 21 through 100).

Why Medicaid, not Medicare, pays for most dementia nursing home care

Because Medicare does not cover custodial dementia care, most people with dementia who live in nursing homes are covered by Medicaid, not Medicare. Medicaid is a joint federal and state program for people with low income and limited assets. Unlike Medicare, Medicaid covers long-term custodial care, including the supervision and personal care that dementia residents need.

Medicaid coverage of nursing homes varies by state — some states cover more services, some cover fewer, and the income and asset limits differ. But in every state, Medicaid will pay for a nursing home stay for dementia if you meet the financial requirements. Many people with dementia spend down their savings until they may have access to for Medicaid, then Medicaid becomes the primary payer for their care.

If you have both Medicare and Medicaid (called "dual may be able to access"), Medicare is the primary payer for skilled services, and Medicaid covers the custodial care and any costs Medicare does not cover. This is why understanding which program covers what is important — it affects what you pay and how long you can stay.

The three-day hospital stay requirement and common gaps

The three-day hospital stay is a hard requirement for Medicare nursing home coverage. The stay must be for inpatient care — observation stays do not count. This is a common source of confusion. If you are admitted to the hospital but placed in "observation status" rather than "inpatient status," those days do not count toward the three-day requirement, even if you spend three calendar days in the hospital.

You can ask the hospital to clarify your status, and you have the right to appeal if you believe you should have been admitted as an inpatient. But the distinction is made by the hospital and Medicare, not by you. If you are unsure, ask the hospital billing department or your discharge planner before you leave.

Another gap: the three-day stay must happen before the nursing home admission. If you go directly to a nursing home from home, or from an assisted living facility, or from a doctor's office, there is no Medicare coverage, regardless of your condition. You would need to be hospitalized first.

What happens when Medicare coverage ends

When your 100 days of Medicare-covered nursing home care end, or when Medicare determines you no longer need skilled care, your coverage stops. At that point, you have several options: pay privately, transition to Medicaid if you may have access to, move to a less expensive setting, or return home with home care services.

The nursing home must notify you in writing before coverage ends, and you have the right to appeal if you disagree with the decision. The appeal process is separate from the nursing home and involves Medicare directly. If you appeal and Medicare upholds the decision, you are responsible for all costs from the date coverage ended, even if you remain in the nursing home during the appeal.

Many people transition to Medicaid at this point. If you have spent down your assets during the Medicare-covered stay, you may now may have access to for Medicaid, which will then cover your continued stay. The nursing home social worker can help you understand whether you may have access to and how the process works.

Medicare Advantage and nursing home coverage

If you have a Medicare Advantage plan (Part C) instead of Original Medicare, your nursing home coverage works differently. Medicare Advantage plans must cover at least what Original Medicare covers, but they may cover more or have different rules about which nursing homes you can use. Some plans cover additional days or waive the copay for days 21 through 100.

You should contact your Medicare Advantage plan before entering a nursing home to understand what it will cover and whether the nursing home you are considering is in the plan's network. Using an out-of-network nursing home may result in higher costs or no coverage at all, depending on your plan.

Frequently Asked Questions

Does Medicare cover dementia care in a nursing home if I did not have a hospital stay?

No. Medicare requires a three-day hospital stay before it will cover any nursing home care. If you enter a nursing home directly from home or from an assisted living facility, Medicare does not pay, regardless of your diagnosis. You would need to be hospitalized first.

Will Medicare pay for my parent's nursing home if they have dementia but no other medical condition?

Only if they were hospitalized for three days and are receiving skilled nursing services ordered by a doctor — such as medication management, wound care, or therapy. Dementia supervision alone is not a skilled service. If that is the only care needed, Medicare does not cover it.

What is the difference between observation and inpatient status, and does it matter for nursing home coverage?

Observation status means you are being monitored but not formally admitted as an inpatient. Observation days do not count toward the three-day requirement for nursing home coverage, even if you spend three calendar days in the hospital. Ask the hospital to clarify your status before discharge.

Can I use my Medicare Advantage plan to cover a nursing home stay for dementia?

Medicare Advantage plans must cover at least what Original Medicare covers, so the same three-day hospital stay and skilled care requirements explore. Some plans offer additional coverage or lower copays. Contact your plan before admission to confirm what it will cover and whether the nursing home is in its network.

If Medicare stops paying after 100 days, can I stay in the nursing home and pay privately?

Yes. You can pay out of pocket for any days beyond the 100 Medicare covers. Many people also transition to Medicaid at this point if they have spent down their assets. The nursing home social worker can help you explore both options.
