The one-sentence version
Medicare pays for short stretches of skilled care after a hospital stay. Medicaid is what pays for most long-term nursing home living. If you remember only one thing, remember that — nearly every other confusion flows from mixing up those two roles.
The two programs, side by side
| Medicare | Medicaid | |
|---|---|---|
| What it is | Federal health insurance, mainly for people 65+ (and some younger people with disabilities) | A joint federal-and-state program for people with limited income and assets |
| Based on | Age or disability — not your income | Financial need — income and assets, with limits set by your state |
| Nursing home role | Short-term skilled care and rehab after a qualifying hospital stay | Long-term nursing home care, month after month, for those who qualify |
| How long it pays | Up to about 100 days per benefit period, only while skilled care is needed | As long as the person qualifies and needs the care — no fixed cutoff |
| Where the rules live | Mostly the same nationwide | Vary state by state, within federal guardrails |
What Medicare actually covers
Medicare covers a skilled nursing facility stay when someone needs daily skilled care — nursing or therapy — after a qualifying hospital admission. In the traditional program, the first 20 days are generally covered in full, and days 21 through 100 carry a daily copay. Coverage lasts only while the skilled need continues; once the person plateaus or just needs help with daily living, Medicare stops.
If your loved one has a Medicare Advantage plan (the private version of Medicare), it covers the same kind of stay, but with its own network, prior-authorization steps, and cost-sharing. Call the plan early — ideally before choosing a facility — and ask which nearby homes are in network.

What Medicaid actually covers
Medicaid is the main payer for long-term nursing home care in the United States. When someone needs to live in a nursing home indefinitely and can't afford the full cost, Medicaid is usually how the bill gets paid. Because it's run by each state, the exact income and asset limits differ — but the shape is consistent:
- Eligibility looks at both income and assets, with limits set by your state. A primary home and one car are often treated differently from savings.
- There are real protections for a spouse who still lives at home — the rules are designed so they aren't left with nothing.
- States review financial transfers from the past several years (commonly five). Giving away money or property shortly before applying can delay eligibility.
- Many people begin as private-pay residents and move onto Medicaid once savings run down. Ask any facility whether it accepts Medicaid and how that transition works there.
Because the asset and transfer rules carry real legal weight, a certified elder-law attorney in your state is worth the consultation fee for anything beyond the basics.
Estimate whether your parent likely qualifies for Medicaid
Can someone have both?
Yes — many older adults are “dual eligible,” meaning they have Medicare and Medicaid at once. In a nursing home that often looks like this: Medicare pays for the first stretch of skilled rehab, and if the person then needs to stay long-term, Medicaid picks up the ongoing cost once they qualify. The two programs hand off rather than compete.
What to do with this
Getting your bearings
- Figure out which stay you're facing: short-term rehab (Medicare's job) or long-term care (Medicaid's job)?
- If it's rehab, ask the facility what happens when covered days end — and start planning for it now
- If long-term care is likely, ask which facilities accept Medicaid and learn your state's basic rules early
- For Medicare Advantage, call the plan before choosing a home to confirm which are in network
- For anything involving spouses, asset transfers, or estates, talk to a certified elder-law attorney
