Who this is for
Patients, caregivers, families, and healthcare workers who hear Medicare and Medicaid used together and need a simple map.
60-second summary
Medicare is federal health insurance mainly based on age, disability, or certain conditions. Medicaid is income/resource-based assistance run by states within federal rules. Some people have both and are called dual eligible. Medicare usually pays first for Medicare-covered services, while Medicaid may help with premiums, cost-sharing, and long-term services for people who qualify.
Fact sheet
Medicare
Federal health insurance mainly for people age 65 or older, certain younger people with disabilities, and people with specific conditions.
- Not generally based on income.
- Includes Part A, Part B, Medicare Advantage, Part D, and sometimes Medigap as a supplement to Original Medicare.
- Can still involve premiums, deductibles, copays, coinsurance, and coverage limits.
Medicaid
A joint federal-state program that helps eligible people with health coverage and certain long-term services under state rules.
- Eligibility and benefits vary by state.
- Rules can involve income, resources, disability status, family status, age, pregnancy, or medical need.
- For older adults, Medicaid can matter when long-term services and supports become the real issue.
Dual eligible
A person who has both Medicare and Medicaid.
- Medicare generally pays first for Medicare-covered services.
- Medicaid may help with Medicare premiums, deductibles, coinsurance, or additional services depending on eligibility.
- Dual-eligible coverage can involve plan choices, coordination rules, and state-specific details.
Which program should a family call?
- Call Medicare or the Medicare plan for Medicare-covered medical benefits, plan rules, drugs, and enrollment questions.
- Call the state Medicaid agency for Medicaid eligibility, long-term services, nursing home Medicaid, or state-specific assistance.
- Call SHIP for free Medicare counseling when comparing options or trying to understand coverage.
Why the difference matters
A 70-year-old patient has Medicare and needs help after a stroke. Medicare may cover certain hospital, physician, drug, and limited skilled rehab costs. If the person later needs ongoing help with bathing, meals, and supervision, Medicaid eligibility may become the bigger question.

Common mistakes
- Thinking Medicare and Medicaid are the same program.
- Assuming Medicare eligibility means Medicaid eligibility.
- Assuming Medicaid rules are identical in every state.
- Ignoring Medicaid until long-term care is already urgent.
Key takeaway
Medicare is mainly health insurance tied to age, disability, or certain conditions. Medicaid is state-administered assistance for people who qualify under income, resource, disability, family, or medical-need rules. Some people need both.
