Medicare covers some Alzheimer's care costs, but not all — and what you pay depends on which type of care you need and which Medicare plan you have

Medicare pays for doctor visits, hospital stays, lab work, and some medications related to Alzheimer's disease. It also covers certain types of care at home and in facilities, though usually only after a hospital stay or when medical need is documented. What Medicare does not cover — and what costs the most — is custodial care, the day-to-day help with bathing, dressing, and meals that many people with Alzheimer's eventually need.

The amount you pay out of pocket depends on whether you have Original Medicare (Parts A and B) or a Medicare Advantage plan, and whether you also have supplemental coverage. This guide explains what each part covers and where the gaps are.

Key Takeaways

  • Medicare Part A covers hospital stays and some skilled nursing facility care after a hospital stay, but only for the first 100 days and only if medical care is needed.
  • Medicare Part B covers doctor visits, diagnostic tests, and some medications used to treat Alzheimer's symptoms, but you pay 20 percent of the cost after your deductible.
  • Medicare does not cover custodial care — help with bathing, dressing, and meals — which is often the largest expense for families managing Alzheimer's at home or in a facility.
  • Medicaid, not Medicare, is the program that typically pays for long-term custodial care in nursing homes, but you must meet income and asset limits.
  • A Medigap (supplemental) plan can reduce your out-of-pocket costs for covered services, but does not fill the gap for custodial care.

What Medicare Part A Covers for Alzheimer's Care

Medicare Part A covers inpatient hospital care when you need treatment for a condition related to Alzheimer's — such as pneumonia, a urinary tract infection, or a fall injury. You pay a deductible for each hospital stay (the amount changes yearly), and then Medicare covers the full cost for the first 60 days. After 60 days, you pay a daily coinsurance amount.

Part A also covers skilled nursing facility (SNF) care — care in a nursing home where a nurse or therapist provides medical treatment — but only under specific conditions. You must have been in a hospital for at least three consecutive days, and you must be admitted to the SNF within 30 days of leaving the hospital. Medicare then covers the full cost of the first 20 days. From day 21 to day 100, you pay a daily coinsurance amount. After 100 days, you pay all costs yourself.

The key word is skilled. If you are in a nursing home only to receive help with daily activities — bathing, dressing, meals — Medicare does not pay, even if a nurse checks on you daily. The care must be medical in nature, ordered by a doctor, and provided by or under the supervision of a nurse or therapist.

What Medicare Part B Covers for Alzheimer's Diagnosis and Treatment

Medicare Part B covers doctor visits with your primary care doctor, neurologist, or geriatrician to diagnose and monitor Alzheimer's disease. It also covers diagnostic tests such as cognitive screening, blood work, and imaging (CT or MRI scans) when ordered by a doctor. You pay 20 percent of the cost after you meet your yearly Part B deductible.

Part B covers some medications used to manage Alzheimer's symptoms. Medications like donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne) — which may slow cognitive decline in early stages — are covered under Part D (prescription drug coverage), not Part B. However, if these drugs are given intravenously in a doctor's office or hospital, Part B may cover the administration cost.

Part B also covers mental health services. If you have depression or anxiety alongside Alzheimer's, you can see a psychiatrist or psychologist for up to 190 visits per year. You pay 20 percent of the cost after your deductible.

Medicare Part D and Prescription Drug Coverage

Medicare Part D covers prescription medications, including drugs prescribed to manage Alzheimer's symptoms or related conditions. Most Alzheimer's medications fall into this category. You choose a Part D plan during enrollment, and coverage varies by plan — each plan has its own list of covered drugs, called a formulary.

You pay a monthly premium for Part D, a yearly deductible (which varies by plan), and then a percentage of the drug cost or a fixed copay depending on the plan and the drug tier. Once your out-of-pocket spending reaches a certain amount in a year, you enter the "donut hole" — a coverage gap where you pay more out of pocket. After you spend enough to exit the donut hole, Medicare pays 95 percent of drug costs for the rest of the year.

If cost is a barrier, ask your doctor about generic versions of Alzheimer's medications or programs that help pay for prescriptions. The Eldercare Locator (1-800-677-1116) can connect you with local resources.

Home Health Care and What Medicare Covers

Medicare Part A covers home health care — nursing, physical therapy, occupational therapy, and speech therapy provided in your home — but only if you meet strict conditions. You must be homebound (unable to leave home without considerable effort), the care must be ordered by a doctor, and it must be medical in nature, not custodial.

For example, Medicare may cover a nurse visiting your home to manage medication, monitor blood pressure, or assess your safety after a fall. It does not cover a home health aide who comes to help you bathe and dress, unless that aide is part of a skilled care plan and works under a nurse's supervision.

Home health care is covered at no cost to you (no copay or coinsurance) as long as the conditions are met. However, the number of visits and length of coverage depend on medical need, and your doctor must recertify the need regularly. If you need ongoing help with daily activities but do not need skilled medical care, Medicare does not pay, and you must turn to Medicaid, private pay, or long-term care insurance.

Hospice Care for Advanced Alzheimer's

Medicare Part A covers hospice care when a doctor certifies that you have six months or less to live. Hospice focuses on comfort and quality of life rather than cure. Medicare covers all hospice services — nursing, doctor visits, medications, equipment, and counseling — at no cost to you.

For people with advanced Alzheimer's who can no longer eat, speak, or recognize family members, hospice can provide pain management, symptom relief, and emotional support. You can receive hospice care at home, in a nursing home, or in a hospice facility. You do not have to be in a hospital or nursing home to be may be able to access.

One important note: choosing hospice means you are no longer pursuing curative treatment for Alzheimer's itself, though you can still receive treatment for other conditions. Talk with your doctor and family about whether hospice is right for you.

The Gap: Custodial Care and Long-Term Support

The largest expense for families managing Alzheimer's is custodial care — help with bathing, dressing, toileting, eating, and other daily activities. Medicare does not pay for this, no matter how advanced the disease or how much help is needed. This is true whether care happens at home, in an assisted living facility, or in a nursing home.

If you need custodial care in a nursing home and your income and assets are low enough, Medicaid — not Medicare — may pay. Medicaid is a joint federal and state program, and rules vary by state. Some states cover nursing home care more generously than others. You can learn about your state's rules by contacting your state Medicaid office or calling the Eldercare Locator at 1-800-677-1116.

If you do not may have access to for Medicaid, you pay for custodial care out of pocket, through long-term care insurance (if you have it), or through family support. Some adult children take unpaid leave from work; others hire private caregivers. The cost of a full-time caregiver or assisted living facility can range widely depending on where you live, but it is often substantial.

Medicare Advantage Plans and Supplemental Coverage

If you have a Medicare Advantage plan (Part C) instead of Original Medicare, your coverage for Alzheimer's care works differently. Medicare Advantage plans are run by private insurance companies and must cover everything Original Medicare covers, but they often add benefits such as dental, vision, or hearing care. However, they may have different copays, coinsurance amounts, and networks of doctors and facilities.

Some Medicare Advantage plans offer supplemental benefits for things like adult day care or in-home support services, but these vary widely by plan and are not may provide. If you are considering a Medicare Advantage plan, ask the plan directly whether it covers any services beyond what Original Medicare covers that might help with Alzheimer's care.

A Medigap (supplemental) plan works with Original Medicare to reduce your out-of-pocket costs for covered services. For example, Medigap can pay your Part B coinsurance (the 20 percent you would normally pay) or your Part A deductible. However, Medigap does not cover services that Medicare does not cover — so it does not help with custodial care.

Frequently Asked Questions

Does Medicare pay for memory care or assisted living?

No. Medicare does not pay for assisted living facilities or memory care units, which provide custodial care and supervision but not skilled medical care. If you need this type of care and cannot pay privately, Medicaid may help if you meet income and asset limits, but rules vary by state.

Will Medicare pay for a caregiver to help at home?

Medicare may pay for a home health aide if the aide is part of a skilled care plan ordered by a doctor — for example, if a nurse is also visiting to manage medications and the aide helps with bathing as part of that plan. Medicare does not pay for a caregiver hired only to help with daily activities. For that, you pay privately or explore Medicaid options.

What happens when I run out of skilled nursing facility coverage after 100 days?

After 100 days in a skilled nursing facility in a calendar year, Medicare stops paying and you must pay all costs yourself. If you need ongoing care, you can stay in the facility and pay out of pocket, move to a different setting, or explore whether Medicaid will pay based on your income and assets.

Can I use Medicare to pay for adult day programs or respite care?

Medicare does not cover adult day programs or respite care (temporary care to give family caregivers a break). Some community programs, senior centers, or Medicaid waiver programs may offer these services at low cost or free, depending on where you live. Contact your local Area Agency on Aging to learn what is available.

Do I need long-term care insurance if I have Medicare?

Medicare does not cover long-term custodial care, so if you want insurance to pay for that type of care, you would need a separate long-term care insurance policy. These policies are expensive and have strict underwriting rules. Talk with a financial advisor or elder law attorney about whether it makes sense for your situation.
