Medicare covers some nursing home costs for dementia, but only under specific conditions
Medicare will pay for a nursing home stay if you have dementia and meet two requirements: you must have been admitted to a hospital for at least three consecutive days (not counting the day you leave), and a doctor must order the nursing home care as part of your recovery from that hospital stay. Medicare does not pay for a nursing home stay that is purely for dementia management or long-term custodial care — it pays only for skilled nursing care, which means medical or nursing services you cannot safely receive at home.
This distinction matters because many people with dementia need a nursing home for supervision and daily living help, not for medical treatment. If that is your situation, Medicare will not cover it, and you will need to pay out of pocket or look into Medicaid, which has different rules.
Key Takeaways
- Medicare covers nursing home care for dementia only if you spent at least three consecutive days in a hospital first and a doctor orders the nursing home stay as part of your recovery.
- Medicare pays for skilled nursing care — wound care, medication management, physical therapy — not for supervision or help with daily activities alone.
- Medicare covers the full cost of days 1 through 20, but you pay a daily copay from day 21 through day 100, after which you pay all costs.
- Medicaid covers long-term nursing home stays for dementia if your income and assets fall below your state's limits, and it covers custodial care that Medicare does not.
- You should ask your hospital discharge planner before leaving the hospital whether Medicare will cover your nursing home stay, because the three-day hospital requirement is strict.
The three-day hospital stay requirement and why it matters
The three consecutive days in the hospital must happen before you enter the nursing home, and they must be days when you are admitted as an inpatient — not days when you are in the emergency room or observation status. This is a common source of confusion. If you spent two days in the hospital and then were moved to observation status on the third day, those three calendar days do not count. Only full inpatient admission days count.
The hospital discharge planner can tell you whether your stay qualifies before you leave. If it does not, Medicare will not cover the nursing home, even if you go there anyway. Ask directly: "Will my hospital stay count toward the three-day requirement for Medicare to cover nursing home care?" If the answer is no, you need to know that before you are discharged so you can plan how to pay.
What "skilled nursing care" means and what it does not cover
Skilled nursing care is medical or nursing work that requires a licensed nurse or therapist. Examples include wound dressing changes, intravenous medication, catheter care, physical therapy after a stroke, or management of a new medication regimen. If you are in the nursing home because you need one or more of these services and cannot safely receive them at home, Medicare may cover the stay.
Skilled nursing care does not include supervision, reminders to take medication, help with bathing or dressing, or monitoring for behavioral changes — even though people with dementia often need all of these things. If the nursing home is providing these services but no skilled nursing care, Medicare will not pay. This is why many people with dementia end up on Medicaid instead: Medicaid covers custodial care and long-term stays that Medicare does not.
How much Medicare pays and for how long
If you meet the requirements, Medicare covers the full cost of the first 20 days in the nursing home with no out-of-pocket cost to you. From day 21 through day 100, you pay a daily copay (the amount changes each year; check with your nursing home or Medicare for the current figure). After day 100 in a benefit period, Medicare stops paying and you pay all costs yourself.
A benefit period begins the day you enter the hospital and ends 60 days after you leave the nursing home. If you return to the hospital and then to a nursing home within that 60-day window, the days do not reset — you continue counting from where you left off. If you stay out of the hospital for 60 days, a new benefit period begins and your day count resets to 1.
Medicaid coverage for dementia in a nursing home
Medicaid is a joint federal and state program that covers long-term nursing home stays for dementia if your income and assets are below your state's limits. Unlike Medicare, Medicaid covers custodial care — the supervision and daily living help that Medicare does not. Medicaid also has no time limit: it can cover a nursing home stay for years if you remain may be able to access.
Each state sets its own income and asset limits, and they vary widely. Some states allow you to keep a home and a car; others count them against your limit. Some states have a monthly income limit of around $2,000; others are higher. You will need to contact your state Medicaid office or a nursing home social worker to learn your state's rules. Many people with dementia eventually move from Medicare to Medicaid as their stay in the nursing home extends beyond 100 days.
What happens when Medicare coverage ends
When you reach day 101 of your nursing home stay, Medicare stops paying. At that point, you have three main options: pay out of pocket if you have the resources, switch to Medicaid if you meet the income and asset limits, or leave the nursing home.
The nursing home must tell you in writing when your Medicare coverage is ending and what your options are. This notice must come at least two days before coverage ends. If you disagree with the decision to stop coverage, you have the right to appeal. The nursing home social worker can help you understand your options and start the Medicaid process if that is the right path for you.
Questions to ask your doctor and the nursing home
Before you are discharged from the hospital, ask your doctor or the discharge planner: "Will my hospital stay count toward the three-day requirement for Medicare to cover nursing home care?" and "How many days of skilled nursing care do you expect I will need?" These answers will tell you whether Medicare will cover any of the stay and for how long.
When you arrive at the nursing home, ask the admissions staff: "How much will Medicare cover, and what will I owe?" and "If my coverage ends before I am ready to leave, what are my options?" Ask for a written summary of what Medicare will and will not pay for. If the nursing home cannot answer these questions clearly, ask to speak with the social worker.
When to contact Medicare or your state Medicaid office
Contact Medicare (1-800-MEDICARE) if you believe your nursing home care should be covered but the nursing home says it is not, or if you receive a notice that your coverage is ending and you disagree. You can also ask for an appeal, and you have the right to have a representative help you with the appeal.
Contact your state Medicaid office if your Medicare coverage is ending and you think you may be may be able to access for Medicaid. Many nursing homes have social workers who can help you start this process. Do not wait until day 100 to ask about Medicaid; the process process can take weeks, and you want to know your options before coverage ends.
Frequently Asked Questions
Does Medicare cover dementia care in a nursing home if I did not spend three days in the hospital?
No. Medicare requires a three-day inpatient hospital stay before it will cover nursing home care. If you did not have that stay, Medicare will not pay for the nursing home, even if you need dementia care. You would need to pay out of pocket or look into Medicaid.
Will Medicare cover my nursing home stay if I only need help with daily activities and supervision, not medical care?
No. Medicare covers skilled nursing care — medical or nursing services — not custodial care like bathing, dressing, or supervision. If that is all you need, Medicare will not pay. Medicaid covers this type of care if you meet your state's income and asset limits.
What if I run out of money before day 100 and Medicare coverage ends?
You can switch to Medicaid if your income and assets fall below your state's limits. Many people "spend down" their savings to become Medicaid-may be able to access. A nursing home social worker or elder law attorney can explain how this works in your state. You should start this conversation before your money runs out.
Can I appeal if Medicare says it will not cover my nursing home stay?
Yes. You have the right to appeal any Medicare decision. You can ask for an appeal in writing or by phone (1-800-MEDICARE). You can also have a representative, such as a family member or attorney, help you with the appeal. The nursing home social worker can explain the appeal process.
Does my supplemental insurance (Medigap) cover the nursing home copay from day 21 to day 100?
Some Medigap plans cover part or all of the daily copay during days 21 through 100. Check your Medigap policy or call your insurance company to see what it covers. This is separate from Medicare and depends on which plan you have.
