Medicare is federal health coverage based mainly on age or disability, while Medicaid is a joint federal-state program based on income and resources. Medicare works the same everywhere; Medicaid rules and eligibility vary by state. People who qualify for both are called dual eligible, and the two programs coordinate.
Key takeaways
- Medicare: mostly age 65+ or qualifying disability, same rules nationwide.
- Medicaid: income and resource based, and rules differ significantly by state.
- You can have both — that's called being dual eligible.
- Medicaid covers some things Medicare doesn't, most notably long-term custodial care.
The core difference
Medicare eligibility is generally about age or disability status. Most people qualify at 65, and some qualify earlier through disability or specific conditions. It's a federal program, so the structure is consistent from state to state.
Medicaid eligibility is about financial need. It's run jointly by the federal government and each state, which means income limits, covered services, and program names vary considerably depending on where you live.
| Medicare | Medicaid | |
|---|---|---|
| Based on | Age 65+ or qualifying disability | Income and resources |
| Administered by | Federal government | State, with federal rules and funding |
| Varies by state | Largely no | Yes, substantially |
| Long-term custodial care | Not covered | Covered for those who qualify |
| Monthly premiums | Part B premium for nearly everyone | Often little or none |
Being eligible for both
A meaningful number of people qualify for both programs. When that happens, Medicare generally pays first and Medicaid picks up costs Medicare doesn't cover, which can include premiums, deductibles, and coinsurance.
Dual eligibility can also open access to specific plan types designed to coordinate both programs in one place. Whether those are available depends on where you live.
The long-term care distinction that matters most
This is where the difference becomes financially enormous for families.
Medicare does not pay for custodial long-term care — ongoing help with bathing, dressing, eating, or supervision. Medicaid does cover long-term care for people who meet its income and asset requirements.
That single difference is why long-term care planning so often ends up being a Medicaid conversation rather than a Medicare one, and why families are blindsided when they assume Medicare will handle it.
Help paying for Medicare if money is tight
Even if you don't qualify for full Medicaid, there are programs that help with Medicare costs and are widely underused because people assume they won't be eligible.
Medicare Savings Programs, administered by states, can help pay Part B premiums and sometimes other cost sharing. Extra Help (the Part D Low-Income Subsidy) can substantially reduce prescription costs. Limits change and vary by state, so it's worth checking rather than assuming.
Common questions
Can you have both Medicare and Medicaid?
Yes. People who qualify for both are dual eligible. Medicare generally pays first, and Medicaid may cover costs Medicare doesn't, including some premiums and cost sharing.
Does Medicaid cover nursing home care?
Yes, for people who meet their state's income and asset requirements. This is a major difference from Medicare, which doesn't cover custodial long-term care at all.
Is Medicaid the same in every state?
No. Medicaid is administered by each state within federal rules, so income limits, covered services, and even the program's name differ from state to state.
What if I don't qualify for Medicaid but still can't afford Medicare?
Look into Medicare Savings Programs and Extra Help for prescription costs. Eligibility limits are higher than many people assume, and both are commonly left unclaimed.
