When Your Medicare Card Expires and What to Do About It

Your Medicare card does expire, and you need a new one before it runs out

Medicare cards issued after 2015 have an expiration date printed on the front. The card itself stops being valid on that date, even though your Medicare coverage continues. You will not be able to use an expired card at the doctor's office, pharmacy, or hospital, and providers may refuse to process claims. The good news is that Social Security sends you a replacement card automatically about three months before yours expires — you do not have to request it.

The expiration date is there for security. Older cards had your Social Security number printed on them, which made identity theft easier. The new cards use a Medicare number instead, and they expire so that old cards with Social Security numbers gradually leave circulation. Your coverage itself does not end when the card expires; only the card stops working.

Key Takeaways

• Your Medicare card has an expiration date on the front, and you cannot use it after that date even though your coverage continues.
• Social Security mails a replacement card automatically three months before expiration; you do not need to request one.
• If your replacement card does not arrive within two weeks of the expiration date, contact Social Security to report it missing.
• You can check your expiration date by looking at the front of your card or logging into your Medicare account online.
• Bring your new card to your next doctor visit and give the new number to your pharmacy and any specialists you see regularly.

How to find your card's expiration date

The expiration date appears on the front of your Medicare card in the bottom right corner. It is printed as a month and year — for example, "05/2026" means the card expires in May 2026. If you cannot find your physical card, you can also see the expiration date by logging into your Medicare account at Medicare.gov. Click "My Health Information" and then "My Claims" to view your card details online.

If you have Original Medicare (Part A and Part B), your card shows one expiration date. If you have a Medicare Advantage plan or a Medigap supplemental policy, you may have multiple cards — one from Medicare and one from your private insurance company. Each card has its own expiration date, and you need to track both.

When Social Security sends your replacement card

Social Security automatically mails a new Medicare card about three months before your current card expires. The card arrives by regular mail, not overnight delivery, so it typically takes one to two weeks to reach you. The new card will have the same Medicare number as your old card but a new expiration date, usually five years later.

You do not need to do anything to receive the replacement card. Social Security has your address on file from when you first enrolled in Medicare. If you have moved recently, update your address with Social Security before your expiration date approaches. You can change your address online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office.

What to do if your replacement card does not arrive

If your card expires and you have not received a replacement, contact Social Security right away. Call 1-800-772-1213 (TTY 1-800-325-0778) and tell them your card is missing or expired. They can verify your Medicare number over the phone and issue a replacement. You can also visit your local Social Security office in person with a photo ID and proof of citizenship or legal residency.

While you wait for a replacement card, you can still see your Medicare number and coverage details online at Medicare.gov. Print a copy of your coverage information and bring it to doctor visits. Most providers can look up your Medicare number in their system even if you do not have the physical card, but having documentation with you speeds up the process. Do not delay scheduling appointments because your card has expired — your coverage is still active.

Using your new card at the doctor and pharmacy

When you receive your new card, bring it to your next doctor visit and give the new Medicare number to your doctor's office. They will update your file with the new number. Do the same at your pharmacy — provide the new number so their system reflects your current card. If you see specialists regularly, call ahead and give them the new number before your next appointment.

Your old card stops working on the expiration date, so do not use it after that. You can throw it away or shred it for security. Some people keep the old card for their records, but it has no legal value once it expires. If you have a Medicare Advantage plan or Medigap policy, your private insurance company will also send you an updated card with the new Medicare number, usually at the same time or shortly after.

What happens if you use an expired card

If you try to use an expired Medicare card at a doctor's office or pharmacy, the provider's system will reject it. The office staff will ask you for a current card or your Medicare number. This can delay your appointment or prescription, but it does not affect your actual coverage. Providers are required to look up your information in the Medicare system if you cannot produce a valid card, though it takes extra time.

If a provider refuses to see you because your card is expired, that is not legal — your coverage is still active. You can give them your Medicare number verbally or show them your online coverage information from Medicare.gov. If a provider continues to refuse service, you can file a complaint with Medicare by calling 1-800-MEDICARE (1-800-633-4227) or visiting Medicare.gov/about-us/contact-us.

Frequently Asked Questions

Does my Medicare coverage end when my card expires?

No. Your Medicare coverage continues without interruption. Only the card itself stops working. You can still see doctors and use your benefits; you just need to provide your Medicare number or get a new card to complete the paperwork at the provider's office.

Can I request a new card before the expiration date?

You can contact Social Security to request an early replacement if your card is damaged, lost, or stolen. Call 1-800-772-1213 or visit your local Social Security office. For a damaged or worn card, they can issue a replacement when ready. For a lost or stolen card, they will verify your identity and mail a new one.

What if I have Medicare Advantage instead of Original Medicare?

Your Medicare card still expires on the same schedule. Your private insurance company will also send you an updated card with your new Medicare number. Bring both cards to your doctor visits — the provider needs your Medicare number and your plan information.

How long does it take to get a replacement card if I call Social Security?

If you call to report a missing or expired card, Social Security will mail a replacement within one to two weeks. If your card is damaged or you need it urgently, visit a Social Security office in person; they can sometimes issue a temporary number while your card is in the mail.

Can I use my Medicare number without the physical card?

Yes. You can give your Medicare number verbally to providers, and they can look it up in their system. However, having the physical card or a printed copy of your coverage information from Medicare.gov makes the process faster at the doctor's office or pharmacy.
