Medicare Card Replacement

If you lost your Medicare card, you can get a free medicare card replacement in three ways: online through your Medicare.gov account, by phone at 1-800-MEDICARE, or in person at a Social Security office. There is no fee for a replacement card, and requesting one does not affect your Part A or Part B enrollment or count as a penalty of any kind. Most replacement cards arrive by mail within 30 days, and an online request is usually the fastest option if you already have a Medicare.gov account set up.

A Medicare card is the identification document issued by the Centers for Medicare & Medicaid Services (CMS), the federal agency that administers the Medicare program, and it lists your name along with your Medicare Number, the identifier providers use to bill for your covered services. If your card is lost, stolen, or damaged, you can replace it without losing coverage or needing to re-enroll.

Three ways to request a replacement Medicare card

Each option below results in the same card being mailed to your address on file. Choose whichever method matches how comfortable you are online and how quickly you need proof of coverage.

Online through your Medicare.gov account

Sign in to your account at Medicare.gov and select the option to request a replacement card. This is generally the fastest method because the request is processed immediately with no hold time. Your new card should arrive by mail within 30 days.

By phone at 1-800-MEDICARE

Call 1-800-MEDICARE (1-800-633-4227), available 24 hours a day, seven days a week. A representative can process the replacement request over the phone and verify your identity using your name, date of birth, and Social Security number if you do not know your Medicare Number. Details on this and other ways to reach Medicare are listed on the official Medicare contact page.

In person at a Social Security office

Because the Social Security Administration handles Medicare enrollment on behalf of CMS, you can also request a replacement card in person at your local Social Security office. This option usually takes the longest because of appointment scheduling and wait times, but it works well if you do not have internet access or prefer face to face help. Use the Social Security office locator to find the nearest location and check whether an appointment is required.

Why your Medicare Number matters

Since April 2018, CMS has issued Medicare cards with a Medicare Beneficiary Identifier, a randomly generated 11 character code, instead of a number based on your Social Security Number. The change was intended to reduce the risk of identity theft if a card is lost, stolen, or intercepted in the mail. Even with that protection, your Medicare Number is still enough information for someone to attempt to bill Medicare fraudulently or seek services in your name, which is why a lost card deserves the same attention as a lost debit card.

If you also have a Medicare Advantage or Medicaid card

Your red, white, and blue Medicare card is separate from any card issued by a private insurer. If you are enrolled in a Medicare Advantage plan rather than Original Medicare, you carry a member ID card from that plan, and a lost Advantage plan card needs to be replaced directly through the plan, not through Medicare.gov.

If you qualify for both Medicare and Medicaid, known as dual eligibility, you have two separate cards and two separate identification numbers. Replacing your Medicare card through the methods above will not replace a lost Medicaid card. Contact your state Medicaid office separately, or see our guide on how Medicare and Medicaid coordinate for what each program covers.
