Medicare covers home health care for dementia patients, but only under specific conditions

Medicare Part A will pay for skilled home health services if a doctor orders them, the patient is homebound, and a Medicare-approved home health agency provides the care. For dementia alone, Medicare does not cover custodial care — the day-to-day help with bathing, dressing, and supervision that dementia patients often need most. Medicare pays only for skilled nursing visits, physical therapy, occupational therapy, or speech therapy ordered by a physician as part of a treatment plan. If your relative needs only supervision and personal care because of dementia, Medicare will not cover it, and you will need to pay out of pocket or turn to Medicaid.

The distinction matters because many families assume Medicare will cover "home health care" as a category. It does not. It covers specific medical services delivered at home. A nurse checking blood pressure or a therapist working on swallowing after a stroke qualifies. A caregiver sitting with someone who wanders or helping them dress does not, even if that person has dementia.

Key Takeaways

  • Medicare Part A covers skilled nursing, therapy, and medical services at home only if a doctor orders them and the patient cannot leave home without help.
  • Custodial care — bathing, dressing, meals, supervision — is not covered by Medicare, even when dementia is the reason it is needed.
  • You must use a Medicare-approved home health agency; Medicare will not reimburse you for hiring a caregiver directly.
  • Medicaid covers custodial care and may cover home health services in addition to Medicare, depending on your state and income.
  • If your relative has both Medicare and Medicaid, Medicaid typically pays for the custodial care that Medicare does not cover.

What Medicare will and will not pay for at home

Medicare Part A covers these services when ordered by a doctor and delivered by a Medicare-approved agency: skilled nursing care (wound care, injections, catheter management, medication monitoring), physical therapy (regaining strength or mobility after a fall or stroke), occupational therapy (relearning daily tasks after an injury), speech-language pathology (swallowing problems, speech loss), and medical social work (counseling related to a medical condition). Home health aides can come as part of a skilled nursing plan, but only to help with activities related to the skilled service — for example, bathing a patient before a wound dressing change.

Medicare will not pay for: a caregiver to provide general supervision, help with bathing or dressing when no medical reason requires it, meal preparation, housekeeping, shopping, transportation, or medication reminders that do not involve skilled assessment. Dementia by itself does not trigger coverage. If your relative has dementia and also had a stroke, and the stroke caused swallowing problems that a speech therapist must address, Medicare covers the therapy. The dementia does not change that. But if the dementia causes wandering and your relative needs someone present to keep them safe, Medicare does not cover it.

How to determine whether your relative meets Medicare's homebound requirement

Before Medicare will pay for any home health service, a doctor must certify that the patient is homebound. Homebound means leaving home requires considerable and taxing effort, or leaving home is medically contraindicated. You do not have to be bedridden. A person who can leave home with help from another person or a walker, but doing so is difficult and exhausting, may still be homebound. A person with dementia who can physically walk but cannot safely leave home alone because they will wander or become lost is typically considered homebound.

The doctor makes this information, not Medicare. Your relative's primary care doctor can make the assessment during an office visit or a home visit. If your relative has not seen a doctor recently, you will need to schedule an appointment — the doctor must see the patient in person to certify homebound status. Once the doctor signs the homebound certification, the home health agency can begin services. If your relative improves and can leave home safely, the doctor will discharge them from home health, and Medicare stops paying.

The role of Medicaid when Medicare does not cover custodial care

Medicaid is the program that covers custodial care — the personal care and supervision that dementia patients usually need. If your relative has both Medicare and Medicaid (called "dual may be able to access"), Medicaid will typically pay for home health aides and caregivers that Medicare does not cover. Medicaid rules and payment rates vary by state, so the amount of care Medicaid will fund and how much it pays the caregiver depends on where you live.

To receive Medicaid coverage for home care, your relative must meet your state's income and asset limits. These limits are lower than many people expect — in most states, a single person can have no more than $2,000 in countable assets and a monthly income below a certain threshold (often around $1,000 to $1,500, but this varies). If your relative's income or assets exceed the limit, they do not may have access to for Medicaid, and you will need to pay for custodial care privately until assets are spent down.

If your relative qualifies for both programs, the process works like this: Medicare pays for any skilled services a doctor orders. Medicaid pays for the custodial care and home health aide time that Medicare does not cover. You will work with both programs' case managers to coordinate. This is one reason to have your relative's Medicaid status checked even if you think they do not may have access to — the rules are complex, and a social worker at the local Medicaid office or a legal aid organization can review your relative's specific situation.

Steps to start the Medicare home health process

First, ask your relative's doctor whether home health services are medically necessary and whether your relative is homebound. The doctor must write an order for specific services — for example, "skilled nursing for wound care, three times per week" or "occupational therapy to address safety concerns after a fall." The order must include the diagnosis (dementia alone is not enough; there must be a medical reason for the service).

Second, choose a Medicare-approved home health agency. You can search for agencies in your area on Medicare.gov or call your local Area Agency on Aging to ask for referrals. When you contact an agency, give them the doctor's order. The agency will verify that Medicare will cover the service and schedule an intake visit. The agency handles all billing to Medicare; you do not submit claims yourself.

Third, the agency's nurse will visit your home, review your relative's medical history, and create a care plan. This plan details what services will be provided, how often, and for how long. Medicare requires a doctor to approve the plan. Once approved, services begin. You will receive a summary of the plan and information about your rights as a patient.

Fourth, expect the first bill to arrive 30 to 60 days after services begin. If your relative has Part A coverage with no remaining deductible, there is no cost to you. If the deductible has not been met, you pay it. After the deductible, Medicare covers 100 percent of approved home health services with no copay.

Common reasons Medicare stops paying for home health

Medicare will end home health coverage if your relative no longer meets the homebound requirement — for example, if they recover enough to leave home safely. The doctor and the home health agency monitor this. If your relative's condition improves, the agency will discharge them, and Medicare stops paying. This is appropriate if recovery is genuine, but it can be a surprise to families who expected ongoing care.

Medicare also stops paying if the skilled service is no longer medically necessary. If your relative was receiving physical therapy after a fall and has regained function, therapy ends. If a wound has healed, skilled nursing visits end. Dementia does not change this — the underlying medical reason for the service must persist.

If your relative needs ongoing custodial care after Medicare home health ends, you will need to pay privately, turn to Medicaid if they may have access to, or explore other options like adult day programs or assisted living. This is why it is important to plan ahead and understand what will happen when Medicare coverage ends.

Medicare Advantage and home health coverage

If your relative has a Medicare Advantage plan (Part C) instead of Original Medicare, home health coverage works differently. Medicare Advantage plans must cover home health services at least as generously as Original Medicare, but they may have different rules about which agencies you can use, how many visits are covered, or what prior approval is needed. Some plans require you to use agencies in their network; others require the plan to approve the service before it begins.

Call your relative's Medicare Advantage plan before asking the doctor for a home health order. Ask whether home health is covered, whether prior approval is needed, and which agencies are in the plan's network. The plan can tell you in one call whether the service will be covered. If the plan denies coverage that Original Medicare would cover, you have the right to appeal.

Frequently Asked Questions

Can Medicare pay for someone to stay with my relative all day to prevent wandering?

No. Supervision and safety monitoring due to dementia alone are custodial care, which Medicare does not cover. If your relative also has a medical condition requiring skilled care — for example, a wound that needs dressing changes — Medicare will cover the skilled nursing visits, and a home health aide may come to help with personal care during those visits. But round-the-clock supervision for dementia is not covered by Medicare.

What if my relative has dementia and also had a recent stroke?

Medicare may cover speech therapy for swallowing problems, physical therapy for mobility, or occupational therapy for relearning daily tasks — all related to the stroke. The dementia does not prevent coverage of these services. However, Medicare still will not cover custodial care or supervision related to the dementia itself. You may need Medicaid or private pay for that part.

Does my relative have to pay anything if Medicare covers home health?

If your relative has Original Medicare and has met their Part A deductible, there is no copay for home health services. If the deductible has not been met, you pay it. If your relative has a Medicare Advantage plan, check the plan's rules — some charge copays per visit, others do not. Call the plan to confirm before services begin.

What happens to home health coverage if my relative moves to assisted living?

Medicare home health is for people who are homebound. If your relative moves to assisted living, they are no longer homebound, and Medicare will end coverage. The assisted living facility may provide personal care, but that is paid separately — either by you, by Medicaid, or by long-term care insurance if your relative has it.

How do I know if my relative qualifies for Medicaid to cover the care Medicare does not?

Contact your state's Medicaid office or your local Area Agency on Aging and ask to speak with a caseworker. They will review your relative's income and assets against your state's limits. You can also call 211 and ask for a Medicaid referral. Bring recent bank statements, proof of income, and a list of assets. The caseworker will tell you whether your relative qualifies and what to do next.
