Medicare covers some dementia care, but not all of it, and what you pay depends on which type of Medicare you have and where you receive care

Original Medicare (Parts A and B) covers doctor visits, hospital stays, and some skilled nursing care related to dementia. It does not cover long-term custodial care — the day-to-day help with bathing, dressing, and meals that many people with dementia need. Medicare Advantage plans (Part C) vary by plan and insurer; some include extra dementia services that Original Medicare does not. Medicaid, a separate program, covers more dementia care than Medicare does, including nursing home stays and home care, but you must meet income and asset limits.

The gap between what Medicare covers and what dementia care actually costs is significant. Many families find they need to combine Medicare coverage with Medicaid, private pay, or long-term care insurance to cover the full cost of care.

Key Takeaways

  • Original Medicare covers doctor visits, hospital care, and skilled nursing for a limited time after hospitalization, but not ongoing custodial care or memory care.
  • Medicare Part D (prescription drug coverage) covers dementia medications, though you pay a monthly premium and may have copays or deductibles.
  • Medicare Advantage plans sometimes include dementia-specific services like adult day programs or in-home care that Original Medicare does not; you must check your individual plan.
  • Medicaid covers nursing home care and long-term home care for people who meet income and asset limits, and works alongside Medicare to fill coverage gaps.
  • Costs for memory care facilities, assisted living, and full-time home aides are typically not covered by Medicare and can range widely depending on your location and the level of care needed.

What Original Medicare Covers for Dementia

Original Medicare Part A covers inpatient hospital care if you are admitted for a condition related to dementia — for example, a fall, infection, or acute confusion that requires hospital-level treatment. Part A also covers up to 100 days in a skilled nursing facility (SNF) after a hospital stay of at least three days, but only if you need skilled nursing or rehabilitation services. The facility must be Medicare-certified. You pay nothing for days 1–3, a daily copay for days 4–20, and a higher daily copay for days 21–100.

Part B covers doctor visits, including visits to your primary care doctor, neurologists, and geriatricians. It also covers certain diagnostic tests — such as cognitive assessments, brain imaging (MRI or CT scans), and lab work — at 80% after you meet your annual deductible. Part B does not cover ongoing supervision, reminders to take medication, or help with activities of daily living, even if a doctor says you need it.

Neither Part A nor Part B covers memory care facilities, assisted living communities, or full-time home health aides for non-medical care. If you need help with bathing, dressing, meals, or medication reminders but do not need skilled nursing, Medicare does not pay for that care.

Medicare Part D and Dementia Medications

Part D is prescription drug coverage run by private insurers under contract with Medicare. It covers medications used to treat dementia symptoms or related conditions — such as donepezil (Aricept), rivastigmine (Exelon), galantamine (Razadyne), and memantine (Namenda) — as well as medications for depression, anxiety, or sleep problems that often accompany dementia.

You pay a monthly premium for Part D, and the amount varies by plan and insurer. When you fill a prescription, you typically pay a copay or coinsurance. Some drugs are on a plan's preferred list (formulary) and cost less; others may require prior approval from the insurer before the pharmacy will fill them. If your doctor prescribes a medication that is not on your plan's formulary, you can ask the plan to make an exception, though this takes time.

If you do not have Part D and later decide you want it, you may face a permanent penalty on your premium if you go without coverage for more than 63 days in a row. The exception is if you have other creditable drug coverage (such as from a current employer or retiree plan).

Medicare Advantage Plans and Dementia Services

Medicare Advantage (Part C) is an alternative to Original Medicare offered by private insurers. These plans must cover everything Original Medicare covers, but many also include extra benefits that Original Medicare does not — such as dental, vision, hearing aids, or fitness programs. Some plans include dementia-specific services like adult day programs, in-home care visits, or care coordination through a geriatric care manager.

The catch is that coverage and costs vary widely from plan to plan and from year to year. A plan that covers adult day programs in 2024 may not in 2025, or the copay may change. You must review your plan's summary of benefits each year during the annual enrollment period (October 15 to December 7) to see what is covered. If your plan drops a service you rely on, you can switch to a different plan during this window.

Medicare Advantage plans also typically have a network of doctors and facilities you must use (except in emergencies). If your preferred neurologist or memory care facility is out of network, you may pay more or have to change providers.

Medicaid and Dementia Care

Medicaid is a joint federal and state program for people with low income and limited assets. Unlike Medicare, Medicaid covers long-term care — including nursing home stays, assisted living in some states, and in-home care — for people who meet the income and asset limits. Each state sets its own limits and rules, so what Medicaid covers in one state may differ from another.

If you have both Medicare and Medicaid (called "dual may be able to access"), Medicaid typically pays for services Medicare does not cover, such as custodial care in a nursing home or ongoing home health aide services. Many people with dementia eventually need Medicaid to cover the cost of full-time care, even if they started out paying privately or relying on Medicare.

To find out whether you might be may be able to access for Medicaid in your state, contact your state Medicaid office or call 211 (a free referral service). You can also visit your state's Medicaid website. The process process varies by state but usually requires proof of income, assets, and citizenship or immigration status.

Home Care and In-Home Services

Medicare covers skilled home health care — nursing visits, physical therapy, occupational therapy, or speech therapy — if a doctor orders it and you are homebound (meaning it is medically difficult for you to leave home). A home health agency must be Medicare-certified. You pay nothing for covered services, though you may have a copay for certain equipment.

Medicare does not cover non-medical home care — a home aide to help with bathing, dressing, meals, or medication reminders. Some Medicare Advantage plans include a limited number of non-medical in-home care visits as an extra benefit, but you must check your plan. If you need ongoing non-medical care, you typically pay out of pocket, use Medicaid (if you are may be able to access), or rely on family caregivers.

Some communities offer programs like adult day centers, which provide supervision, activities, and meals during the day while a family caregiver works. These programs are rarely covered by Medicare, though some Medicaid programs or local Area Agencies on Aging may help pay for them. Call your local Area Agency on Aging to ask what programs are available in your area.

Costs You May Face Out of Pocket

Even with Medicare, you will likely have costs. Original Medicare Part B has an annual deductible (currently $240, though this changes yearly) and covers 80% of approved services after you meet it. If you see a doctor who does not accept Medicare assignment, you may pay more. Prescription drugs have copays or coinsurance. If you need skilled nursing care, you pay a daily copay after day 3.

The biggest out-of-pocket costs usually come from services Medicare does not cover at all: memory care facilities, assisted living, full-time home aides, and adult day programs. These costs vary widely by location. A memory care facility might cost $4,000 to $8,000 per month or more, depending on where you live and the level of care. A full-time home aide might cost $15 to $25 per hour or more, which adds up quickly.

Some families use long-term care insurance to help cover these costs, though policies must be purchased before a dementia diagnosis. Others use a combination of Medicare, Medicaid, private pay, and family caregiving. A geriatric care manager or social worker can help you understand your options and plan for costs.

Frequently Asked Questions

Does Medicare cover memory care facilities?

No. Medicare does not cover the cost of living in a memory care facility or assisted living community. These are considered custodial care, not medical care. If you need Medicaid to help pay, you must meet your state's income and asset limits, and Medicaid coverage varies by state.

Will Medicare pay for a home aide to help my parent with dementia?

Only if the aide is providing skilled nursing or therapy services ordered by a doctor and the person is homebound. Medicare does not pay for non-medical help with bathing, dressing, meals, or medication reminders. Some Medicare Advantage plans include a limited number of non-medical in-home visits; check your plan's benefits.

What happens to Medicare coverage if my parent moves to a nursing home?

Medicare Part A can cover up to 100 days in a skilled nursing facility after a hospital stay, but only if skilled care is needed. If your parent is in a nursing home for custodial care only (help with daily activities), Medicare does not pay. Medicaid may cover long-term nursing home care if your parent meets income and asset limits.

Does Medicare cover dementia medications?

Yes, through Part D (prescription drug coverage). Part D covers dementia medications like donepezil and memantine, as well as medications for depression or anxiety. You pay a monthly premium and copays at the pharmacy. If you do not have Part D, you may face a penalty if you enroll later.

Can I switch from Original Medicare to a Medicare Advantage plan if my parent has dementia?

Yes, during the annual enrollment period (October 15 to December 7) or if you are newly may be able to access for Medicare. Some Medicare Advantage plans include dementia services that Original Medicare does not, but coverage varies by plan and changes yearly. Review the plan's benefits summary before you enroll to see what is covered.
