These two get confused constantly, and the confusion is expensive. The short version: Medicare is health insurance. Medicaid is the program that actually pays for long-term care.
This is a general overview of the US programs, not advice about your situation. Rules change annually and Medicaid varies substantially by state — verify current specifics with your State Health Insurance Assistance Program (SHIP), which offers free counseling, or an elder law attorney.
Medicare
Federal health insurance, primarily for people 65 and older, plus some younger people with disabilities or end-stage renal disease. Eligibility is based on age and work history — not on income or assets.
It comes in parts:
- Part A — hospital stays, limited skilled nursing facility care, hospice, some home health
- Part B — doctor visits, outpatient care, durable medical equipment
- Part C (Medicare Advantage) — a private plan that bundles A and B, usually with drug coverage; networks and rules differ from traditional Medicare
- Part D — prescription drugs
The gap that surprises everyone
Medicare does not pay for long-term custodial care.
Custodial care means help with daily living — bathing, dressing, eating, using the bathroom, supervision for someone with dementia. It is exactly what most aging people need most, for the longest time, and Medicare does not cover it. Not in a nursing home, not in assisted living, not at home.
What Medicare does cover is limited and skilled:
- Skilled nursing facility care after a qualifying inpatient hospital stay, for a capped number of days, and only while the person needs genuinely skilled care and is progressing. The first stretch is covered in full; after that a daily coinsurance applies. This is rehab, not long-term residence — and it ends.
- Home health, if the person is homebound and needs intermittent skilled nursing or therapy. This does not mean an aide who comes to help with daily tasks indefinitely.
Families routinely plan around an assumption that Medicare will cover a nursing home. It won't. That assumption is the single most common financial mistake in caregiving.
Medicaid
A joint federal-state program based on financial need. Unlike Medicare, eligibility depends on income and assets, and both the limits and the program's name differ by state (Medi-Cal in California, MassHealth in Massachusetts, and so on).
Medicaid does cover long-term custodial care, including nursing home care, and in most states covers some home- and community-based services that let people stay at home instead. Those home-based programs often have waiting lists, so it's worth asking early rather than at crisis point.
Two things to understand before you plan around it:
Asset limits. Qualifying generally requires assets below a threshold. Rules protecting a spouse who still lives at home are a genuinely important and complicated area — a "community spouse" is not required to become destitute, and the protections are worth getting professional advice about.
The look-back period. When someone applies for Medicaid long-term care, the state reviews financial transfers from roughly the preceding five years. Assets given away or sold below value in that window can trigger a penalty period of ineligibility. This is why "just give the house to the kids" is usually bad advice, and why timing matters enormously.
You can have both
Many older adults are "dual eligible" — Medicare as their primary health insurance, Medicaid covering long-term care plus costs Medicare doesn't, like premiums and coinsurance. If someone is on Medicare and their money is running low, Medicaid is worth investigating rather than assuming they don't qualify.
Where to actually get help
- Your State Health Insurance Assistance Program (SHIP) — free, unbiased Medicare counseling in every state
- Your Area Agency on Aging — the local hub for benefits and services; find yours through the Eldercare Locator
- An elder law attorney — worth the cost before any significant asset transfer or Medicaid application, because mistakes here are hard to reverse
Two things worth doing now
Find out which Medicare setup your loved one actually has — traditional Medicare with a supplement, or a Medicare Advantage plan — because the rules differ meaningfully. And get a realistic picture of their assets and income before a crisis, not during one. Medicaid planning done years ahead has options; Medicaid planning done from a hospital bed has very few.
