How to Tell If You Have Medicaid or Medicare

The fastest way to know which program you're on

Check your insurance card. If it says Medicaid anywhere on the front, you have Medicaid. If it says Medicare, you have Medicare. The card itself is the clearest answer — it will have your program name printed on it, along with your member ID number.

If you cannot find your card, call the number on any medical bill you received in the past year. The billing department can tell you which program paid for that visit. You can also contact your state's Medicaid office directly — each state runs its own program and keeps records of who is enrolled.

Medicare has a phone line too: 1-800-MEDICARE (1-800-633-4227). They can confirm your enrollment and send you a replacement card if yours is lost.

Key Takeaways

Your insurance card will print either "Medicaid" or "Medicare" on the front, which is the quickest way to tell which program covers you.
Medicaid is state-run and covers people with low income; Medicare is federal and covers people 65 and older or with certain disabilities.
You cannot have both programs at the same time, though some people move from one to the other when their circumstances change.
If you have lost your card, any recent medical bill or a phone call to your state Medicaid office will confirm which program you are on.

Why the two programs are straightforward to confuse

Both programs have similar names and both pay for medical care, but they are completely separate. Medicaid is run by your state and covers people with low income, regardless of age. Medicare is run by the federal government and covers people 65 and older, plus some younger people with disabilities or end-stage renal disease.

The confusion happens because the names sound alike and because some people move from one program to the other. For example, a person on Medicaid at age 30 might turn 65 and move to Medicare. But you cannot be on both programs at the same time — you are either on one or the other.

What your Medicaid card looks like

A Medicaid card is issued by your state, so the design varies. Most cards are the size of a credit card and have your name, a member ID number, and the word "Medicaid" printed on the front. Some states print the program name as "Medicaid" while others may say "Medical information" or use the state's specific program name — for example, California calls it "Medi-Cal" and New York calls it "Medicaid".

The back of the card usually lists customer service numbers and may show which services are covered. If you are unsure whether a card is Medicaid, look for your state's name and the word "Medicaid" or your state's equivalent term. The card will also have an expiration date, though Medicaid coverage often renews automatically.

What your Medicare card looks like

A Medicare card is issued by the federal government and looks the same regardless of which state you live in. It is the size of a credit card and has your name, a nine-digit Medicare number, and the word "Medicare" printed on the front. The card shows which parts of Medicare you have — Part A (hospital insurance), Part B (medical insurance), Part D (prescription drug coverage), or a combination.

Medicare cards are red, white, and blue. The back lists customer service numbers. If you turned 65 recently, you should have received your card automatically; if you did not, you can request one by calling 1-800-MEDICARE.

How to find your program if you have no card

Look for any medical bill or explanation of benefits from the past year. The bill will show which insurance program paid for the visit. The program name will appear near the top or in the "insurance information" section. If the bill says "Medicaid" or your state's Medicaid name, you are on Medicaid. If it says "Medicare", you are on Medicare.

You can also call your doctor's office or the hospital where you received care. Give them your name and date of birth, and they can look up which insurance you had on file when you visited. This is usually the fastest way if you have a recent appointment.

If you have no bills or recent appointments, contact your state's Medicaid office. You can find the phone number by searching "[your state] Medicaid office" online, or by calling 211, which is a free referral line that connects you to local health programs. For Medicare, call 1-800-MEDICARE.

What happens if you think you have the wrong program

If your card says Medicaid but you believe you should be on Medicare (for example, because you are 65 or older), contact your state Medicaid office. They can review your case and help you move to Medicare if you are now may be able to access. You may need to provide proof of age or citizenship.

If your card says Medicare but you believe you should be on Medicaid (for example, because your income dropped), contact your state Medicaid office. Some people are may be able to access for both programs at the same time in rare situations, though this is uncommon. Your state office can tell you whether you meet the income and other requirements for Medicaid in your state.

Frequently Asked Questions

Can I have both Medicaid and Medicare at the same time?

In almost all cases, no. You are either on Medicaid or Medicare. However, a small number of people called "dual may be able to access" may receive some benefits from both programs in specific situations. Contact your state Medicaid office to find out whether you might be one of them.

What if my card expired?

For Medicaid, contact your state Medicaid office — they can issue a replacement or confirm your coverage is still active. For Medicare, call 1-800-MEDICARE and request a new card. Both programs will send a replacement card by mail, usually within two weeks.

Does my card being expired mean my coverage ended?

Not necessarily. Medicaid coverage often continues even after the card expires — the card is just outdated. Medicare coverage also continues past the expiration date on the card. Call your program to confirm your coverage is still active, and request a new card if you need one for a doctor's visit.

What if I lost my card and need to see a doctor today?

Call your doctor's office and tell them you are on Medicaid or Medicare but do not have your card. Give them your name, date of birth, and Social Security number if they ask. Most offices can look up your coverage in their system. You can also call your state Medicaid office or 1-800-MEDICARE to confirm your coverage before your appointment.

How do I know which state Medicaid office to call?

Search "[your state] Medicaid office" online, or call 211 and tell them you need to reach your state's Medicaid program. They will give you the phone number. You can also visit your state's health department website — it usually has a link to the Medicaid office.
