No, Medicare and Medicaid are two separate government programs with different rules, costs, and who they cover
The names sound alike, but Medicare and Medicaid are completely different programs run by different federal agencies. Medicare is for people 65 and older, regardless of income — it's a health insurance program you pay into through payroll taxes during your working years. Medicaid is a joint federal and state program for people with lower incomes, and the rules change depending on which state you live in. Mixing them up can cost you money or cause you to miss out on coverage you're may have access to to.
Many people have both programs at the same time — this is called being "dual may be able to access" — but that doesn't make them the same thing. Understanding which program covers what will help you make better decisions about your health care and your wallet.
Key Takeaways
- Medicare is for people 65 and older and is based on age and work history, while Medicaid is for people with lower incomes and varies by state.
- Medicare is run by the federal government; Medicaid is run jointly by federal and state governments, so rules differ where you live.
- Medicare requires monthly premiums and has deductibles and copays; Medicaid is usually free or very low-cost for those who meet income limits.
- You can have both Medicare and Medicaid at the same time, and when you do, Medicaid often covers costs that Medicare doesn't.
- Enrollment important date and rules are different for each program, so missing a important date for one doesn't affect the other.
Who each program is designed for
Medicare is for people who are 65 or older, or younger people with certain disabilities or end-stage renal disease. You don't have to be poor to get Medicare — if you're 65, you're in. The program is based on your age and your work history (or your spouse's work history). Most people pay into Medicare through payroll taxes while they work, so by the time they turn 65, they've already "paid for" the program.
Medicaid is for people with lower incomes and limited assets. The income and asset limits vary by state — what qualifies you in one state may not in another. Medicaid also covers some groups that Medicare doesn't, like pregnant women, children, and people with disabilities under working age. You don't have to be retired or a certain age to get Medicaid; you just have to meet your state's income and resource rules.
How much each program costs you
Medicare has monthly premiums, deductibles, and copays. Part A (hospital insurance) is usually free if you or your spouse paid Medicare taxes for at least 10 years. Part B (medical insurance) costs a monthly premium that goes up based on your income — in 2024, the standard premium is $164.90 per month, but higher earners pay more. You also pay a deductible before coverage kicks in, and you pay copays or coinsurance when you use services.
Medicaid is usually free or very low-cost. Some states charge small copays for certain services, but most people on Medicaid pay nothing or very little. Because Medicaid is run by states, the exact costs vary — some states charge nothing at all, while others charge a few dollars per visit. If you're on both Medicare and Medicaid, Medicaid often pays the premiums and cost-sharing that Medicare requires.
What each program covers
Medicare covers hospital stays, doctor visits, lab tests, imaging, and some preventive care. It also covers prescription drugs through Part D, though you choose a separate plan for that. Medicare does not cover long-term care (like nursing home stays), dental, vision, or hearing aids — though some Medicare Advantage plans add these benefits. Medicare covers what it covers the same way in every state.
Medicaid covers doctor visits, hospital stays, lab tests, and prescription drugs. It also covers services Medicare doesn't, like long-term care in a nursing home, dental care, and vision care — but again, what's covered depends on your state. Some states are more generous than others. Medicaid also covers family planning, pregnancy and childbirth, and mental health services in ways Medicare may not.
How enrollment works for each program
You enroll in Medicare when you turn 65. You can sign up during your Initial Enrollment Period, which is the three months before your 65th birthday, the month you turn 65, and the three months after. If you miss this window, you pay a penalty for the rest of your life, so the important date matters. You enroll through Social Security or Medicare.gov.
Medicaid enrollment varies by state. Some states have open enrollment year-round, while others have specific enrollment periods. Many states expanded Medicaid in recent years, changing who can enroll. You explore through your state's Medicaid office or through Healthcare.gov. Missing a Medicaid enrollment important date usually doesn't penalize you the way missing Medicare's does — you can often explore later when you become may be able to access.
What happens if you have both Medicare and Medicaid
If you're 65 or older and have a low income, you may have both programs. This is called being "dual may be able to access." When you have both, Medicare is your primary insurance — it pays first. Medicaid is secondary and covers costs that Medicare doesn't pay, like copays, deductibles, and some services Medicare excludes.
Having both programs is actually an advantage. Your out-of-pocket costs are much lower because Medicaid fills in the gaps. If you're dual may be able to access, you're usually automatically enrolled in both, but you should verify this with your state Medicaid office and Medicare. Some people are dual may be able to access but don't realize it and end up paying costs they didn't have to.
Common reasons people confuse the two programs
The names are similar, and both are government health insurance programs, so it's straightforward to mix them up. Both use cards that look similar. Both have enrollment periods and rules that change. Both cover doctor visits and hospital care. But the similarities end there — the funding, the may be able to access rules, the costs, and the coverage are all different.
Another source of confusion is that some people have both programs at the same time, which can make it seem like they're the same thing. But having both just means you're covered by two separate programs that work together. It's like having car insurance and homeowners insurance — they're different policies that cover different things, even though you hold both.
Frequently Asked Questions
Can I have Medicare and Medicaid at the same time?
Yes. If you're 65 or older and have a low income, you may have both. Medicare pays first, and Medicaid covers costs Medicare doesn't, like copays and deductibles. This is called being "dual may be able to access" and usually lowers your out-of-pocket costs significantly.
Do I have to pay for Medicare?
Part A (hospital insurance) is usually free if you or your spouse paid Medicare taxes for at least 10 years. Part B (medical insurance) costs a monthly premium — the standard is $164.90 in 2024, though higher earners pay more. You also pay deductibles and copays when you use services.
Do I have to pay for Medicaid?
Medicaid is usually free or very low-cost. Some states charge small copays for certain services, but most people on Medicaid pay nothing. The exact cost depends on your state's rules.
What if I'm under 65 and don't have health insurance?
You may be able to get Medicaid if your income is low enough — the limit depends on your state. You can also look at plans through Healthcare.gov. You cannot get Medicare just because you don't have insurance; Medicare is for people 65 and older (with rare exceptions for certain disabilities).
If I miss the Medicare enrollment important date, can I still enroll later?
You can enroll later, but you'll pay a penalty for each month you were late. The penalty is added to your Part B premium for the rest of your life. It's important to enroll during your Initial Enrollment Period — the three months before your 65th birthday, the month you turn 65, and the three months after.
