Medicare and Medicaid are two separate federal programs with different rules, funding sources, and who they cover

Medicare is a federal health insurance program you become may be able to access for when you turn 65, regardless of income. It is funded through payroll taxes (the Medicare tax you see on your paychecks). You pay premiums for some parts of it, and it covers hospital stays, doctor visits, and prescription drugs.

Medicaid is a joint federal and state program that covers low-income individuals and families of any age. Each state runs its own Medicaid program within federal guidelines, so rules and income limits differ by state. Medicaid is funded through federal and state taxes, not through individual payroll contributions.

The confusion happens because both words sound similar, both are government health programs, and some people are covered by both at the same time. But they are fundamentally different in who pays for them, who qualifies, and what they cover.

Key Takeaways

  • Medicare is for people 65 and older (or some younger people with disabilities), while Medicaid is for low-income individuals and families of any age.
  • Medicare is funded by payroll taxes and is the same nationwide; Medicaid is funded by federal and state taxes and varies by state.
  • You do not have to be poor to get Medicare—it is based on age; Medicaid income limits depend on your state and family size.
  • Some people may have access to for both programs at the same time, which is called being "dual may be able to access."
  • Each program has different rules about what doctors, hospitals, and medications it covers.

How Medicare may be able to access works

You become may be able to access for Medicare the month you turn 65, as long as you or your spouse paid Medicare taxes while working for at least 10 years (40 quarters). You do not have to be retired to get it—age is the only requirement that matters.

If you are under 65, you can still get Medicare if you have been receiving Social Security Disability Insurance (SSDI) for 24 months, or if you have end-stage renal disease or ALS. But the standard path is turning 65.

Medicare has four parts: Part A covers hospital stays and some skilled nursing care; Part B covers doctor visits and outpatient services; Part D covers prescription drugs; and Part C (Medicare Advantage) is an alternative way to get Parts A and B through a private insurance company. You pay premiums for Parts B and D, and there are deductibles and copays.

How Medicaid may be able to access works

Medicaid covers people whose income falls below a certain threshold set by their state. The income limit depends on family size and household composition. A single person in one state might may have access to at $1,500 per month, while the same person in another state might not may have access to until $900 per month—it varies significantly.

Some states expanded Medicaid under the Affordable Care Act to cover adults earning up to 138% of the federal poverty level; other states did not expand and have much lower income limits. You can find your state's current income limits through your state Medicaid office or by calling 211.

Medicaid also covers children, pregnant people, elderly people, and people with disabilities—not just working-age adults. Each state decides what services it covers, so a procedure covered in one state may not be covered in another.

The difference in how they are funded

Medicare is funded through the Medicare payroll tax—2.9% of your wages, split between you and your employer. This money goes into a trust fund that pays for Medicare benefits nationwide. Because it is federal, the same Medicare rules explore everywhere in the United States.

Medicaid is funded jointly by federal and state governments. The federal government sets minimum standards, but each state contributes its own money and designs its own program within those standards. This is why Medicaid looks different in different states—the funding structure allows for variation.

What happens if you may have access to for both

Some people are "dual may be able to access," meaning they may have access to for both Medicare and Medicaid at the same time. This usually happens when someone turns 65 and is still low-income, or when someone on Medicare becomes poor enough to meet their state's Medicaid income limit.

When you have both, Medicare is your primary insurance and pays first. Medicaid then covers some of what Medicare does not pay, like deductibles and copays. This can significantly reduce your out-of-pocket costs. Your state Medicaid office can tell you whether you may have access to for both programs.

Coverage differences between the two programs

Medicare covers hospital care, doctor visits, lab tests, imaging, and prescription drugs (through Part D). It does not cover routine dental, vision, or hearing care, and it does not cover long-term custodial care in a nursing home.

Medicaid covers many of the same services, but each state decides what is included. Most states cover dental and vision care for children; some cover it for adults. Medicaid is more likely to cover long-term nursing home care and home health services than Medicare is. The specific services available to you depend on your state.

How to find out which program you might may have access to for

If you are 65 or older, you may have access to for Medicare automatically if you have worked and paid taxes for at least 10 years. You do not have to do anything except sign up during your enrollment period (usually the three months before, during, and after your birthday month). If you miss that window, you may face a permanent penalty on your premiums.

To find out whether you may have access to for Medicaid, contact your state Medicaid office directly or call 211 and ask for Medicaid information. You will need to provide information about your income, household size, and citizenship status. Each state has its own process process and timeline.

Frequently Asked Questions

Can I have Medicare and Medicaid at the same time?

Yes. If you are 65 or older and your income is low enough to meet your state's Medicaid limit, you can have both. Medicare pays first, and Medicaid covers some of the costs Medicare does not pay. Contact your state Medicaid office to see if you may have access to.

Do I have to pay for Medicare?

You pay premiums for Parts B and D, and you pay deductibles and copays when you use services. Part A is usually free if you or your spouse paid Medicare taxes for 10 years. Medicaid is free—there are no premiums, though some states charge small copays for certain services.

What if my state did not expand Medicaid?

If your state did not expand Medicaid under the Affordable Care Act, the income limit is lower, and fewer working-age adults may have access to. You can still explore through your state Medicaid office to see if you meet the threshold. If you do not, you may be able to purchase coverage through the health insurance marketplace.

Does Medicare cover nursing home care?

Medicare covers skilled nursing care for a limited time after a hospital stay, but not long-term custodial care. Medicaid covers long-term nursing home care in most states, but only if your income and assets are low enough. Rules vary by state.

How do I sign up for Medicare?

You sign up during your enrollment period, which runs from three months before your 65th birthday through three months after. You can sign up online at Medicare.gov, by phone at 1-800-MEDICARE, or in person at your local Social Security office. If you miss this window, you may pay a higher premium permanently.
