No — Medicaid and Medicare are separate federal programs with different rules, different funding, and different people they serve

The names sound alike, but they are not the same thing. Medicare is a federal health insurance program run by the Centers for Medicare & Medicaid Services (CMS). It covers people age 65 and older, some younger people with disabilities, and people with end-stage renal disease. You pay into Medicare through payroll taxes during your working years, and it works like traditional health insurance — you have premiums, deductibles, and copays.

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 the income limits, covered services, and rules vary by state. Medicaid is funded through general tax revenue, not payroll deductions, and it is means-tested — you must meet income and asset limits to be covered.

The confusion happens because both programs are managed by the same federal agency (CMS) and both are health insurance. But they are funded differently, serve different populations, and have different may be able to access rules. You can be on both at the same time — this is called "dual may be able to access" — but that is the only overlap.

Key Takeaways

  • Medicare is age-based (65+) or disability-based and funded through payroll taxes; Medicaid is income-based and funded through general tax revenue.
  • Medicare is the same nationwide; Medicaid rules, income limits, and covered services vary by state.
  • Medicare requires you to have worked and paid into the system; Medicaid does not.
  • You can be on both programs at the same time if you meet the requirements for each.
  • Some people may have access to for both because they are over 65 and have low income, or because they are disabled and have low income.

Who Medicare Covers

Medicare covers people age 65 and older, regardless of income. You do not have to be poor to get Medicare — if you are 65, you are may be able to access. You also do not have to be retired; you can still be working.

Medicare also covers some people under 65: those who have been receiving Social Security Disability Insurance (SSDI) for at least 24 months, and people of any age with end-stage renal disease or ALS. These are the only exceptions to the age rule.

To get Medicare, you must have worked and paid Medicare taxes for at least 10 years (40 quarters). If you have not worked that long, you may be covered as a spouse or former spouse of someone who has.

Who Medicaid Covers

Medicaid covers low-income individuals and families. There is no age requirement — Medicaid covers children, working-age adults, seniors, and people with disabilities. The income limit depends on your state and your household size.

You do not have to have worked to get Medicaid. You do not have to have paid any taxes. You only have to meet your state's income and asset limits. Each state sets its own limits, so a household that qualifies in one state might not may have access to in another.

Some groups are covered in every state — children, pregnant people, and parents of dependent children (though the income limits vary). Other groups, like working-age adults without children, are covered in some states but not others, depending on whether that state expanded Medicaid under the Affordable Care Act.

How They Pay for Services

Medicare is funded through payroll taxes. When you work, you and your employer each pay 1.45% of your wages into Medicare. Self-employed people pay 2.9%. This money goes into a trust fund that pays for your coverage once you turn 65 or become disabled.

Medicaid is funded through federal and state general tax revenue — income tax, sales tax, and other sources. There is no separate payroll deduction for Medicaid. The federal government pays a share of each state's Medicaid costs, and the state pays the rest. This is why Medicaid rules differ by state — states have some control over how much they spend and who they cover.

Coverage and Cost Differences

Medicare has four parts: Part A (hospital), Part B (doctor and outpatient), Part D (prescription drugs), and Part C (an alternative private plan). You pay premiums for Parts B and D, and you have deductibles and copays. Medicare does not cover dental, vision, or hearing aids unless you choose a Part C plan that includes them.

Medicaid coverage varies by state, but it typically covers doctor visits, hospital stays, prescription drugs, and preventive care. Many state Medicaid programs also cover dental, vision, and hearing aids — something Medicare does not. Medicaid usually has lower or no copays and deductibles than Medicare, especially for low-income people.

If you are on both Medicare and Medicaid (dual may be able to access), Medicaid usually pays your Medicare premiums, deductibles, and copays. This is called "Medicare Savings Programs" or "Medicaid Buy-In" depending on your state.

How to Know Which Program You Might Be On

If you are 65 or older, you are almost certainly on Medicare. You get a Medicare card in the mail when you turn 65, even if you do not sign up. If you are under 65 and have been on SSDI for 24 months, you are on Medicare.

If you have low income, you may be on Medicaid. Your state Medicaid program will tell you whether you meet the income limit. You can contact your state Medicaid office or use the 211 helpline to find out what your state's limits are and whether you might be covered.

If you are 65 or older and have low income, you might be on both. Contact your state Medicaid office to see if you may have access to for Medicaid to help pay your Medicare costs.

What Happens If You Are on Both

If you are on both Medicare and Medicaid, Medicare is your primary insurance — it pays first. Medicaid is secondary — it pays what Medicare does not cover. In most cases, Medicaid will pay your Medicare premiums, deductibles, and copays, so you have very low out-of-pocket costs.

Being on both is actually beneficial because you get the broader coverage of Medicaid (like dental and vision) plus the stability of Medicare. You keep both cards and use both programs.

You do not have to do anything special to coordinate them — the programs communicate with each other. But you should tell your doctor that you have both, so the office bills correctly.

Frequently Asked Questions

Can I be on Medicare and Medicaid at the same time?

Yes. If you are 65 or older and have low income, or if you are disabled and have low income, you may may have access to for both. Medicare covers you based on age or disability; Medicaid covers you based on income. You can meet both requirements at once.

I am 62 and have low income. Can I get Medicaid?

Yes, if your income is below your state's limit. Medicaid has no age requirement. You do not have to be 65. Contact your state Medicaid office or call 211 to find out your state's income limit for your household size.

I worked for 5 years. Can I get Medicare?

No. Medicare requires 10 years of work history (40 quarters). If you have not worked that long, you may be covered as a spouse or former spouse of someone who has worked 10 years. You might still be covered by Medicaid if your income is low enough.

Does Medicare cover dental and vision?

Original Medicare (Parts A and B) does not cover dental, vision, or hearing aids. Some Part C plans include these benefits. If you are on both Medicare and Medicaid, your state Medicaid program may cover dental and vision, so check with your state.

How do I know which program to contact with a question?

If your question is about coverage, premiums, or claims, contact the program that covers the service. For Medicare questions, call 1-800-MEDICARE. For Medicaid questions, contact your state Medicaid office. If you are on both, start with whichever program covers the service you are asking about.
