What To Do If You've Lost Your Medicare Card

How to replace your Medicare card

You can order a replacement Medicare card online through your Medicare account, by phone, or by mail. The fastest way is online at Medicare.gov — you can request a new card in minutes if you have a login. If you don't have an online account, you can create one during the replacement request, and Medicare will mail the card to you within 7 to 10 business days.

If you prefer to call, dial 1-800-MEDICARE (1-800-633-4227) and tell the representative you need a replacement card. They'll verify your identity by asking for your Social Security number and date of birth. The card will arrive by mail in the same timeframe.

You can also mail a request to the address on the back of any Medicare documents you have, or visit your local Social Security office in person. Mailing takes longer — usually 2 to 3 weeks — so use this option only if online or phone access isn't possible for you.

Key Takeaways

• Order a replacement card online at Medicare.gov, by phone at 1-800-MEDICARE, or by mail; online is fastest at 7 to 10 business days.
• You'll need your Social Security number and date of birth to verify your identity, whether you order online or by phone.
• Your Medicare number stays the same even if your card is lost, so you can still use your benefits while waiting for the replacement.
• If you need your Medicare number before the card arrives, you can find it in your online Medicare account or by calling 1-800-MEDICARE.
• You do not need to pay any fee to replace a lost Medicare card.

Using your benefits while you wait for the replacement

Your Medicare coverage doesn't stop when your card is lost. Your Medicare number is what matters to doctors, hospitals, and pharmacies — not the physical card. You can give your Medicare number to any provider who needs it, and they can look up your coverage in their system.

If you don't have your number memorized, you can find it by logging into your Medicare account at Medicare.gov, or by calling 1-800-MEDICARE. Write down the number and keep it somewhere safe so you have it while waiting for the replacement card to arrive.

Some people carry a photo or screenshot of their Medicare number on their phone for appointments. This is a practical workaround while your replacement card is in the mail.

What to do if your card was stolen or you suspect fraud

If you believe someone may have used your Medicare number or card fraudulently, call 1-800-MEDICARE right away. The representative can flag your account and watch for unusual activity. They may also issue you a new Medicare number in addition to a replacement card, though this is less common.

You can also report suspected Medicare fraud directly to the Office of Inspector General at 1-800-HHS-TIPS (1-800-447-8477) or online at oig.hhs.gov. Keep a record of any fraudulent charges you notice on your Medicare statements, and report them to your doctor's office or the provider involved.

Check your Medicare statements regularly — you can view them online through your Medicare account. Look for services or charges you don't recognize, and report them promptly.

Updating your address if your card goes to the wrong place

If you've moved recently and your replacement card might go to an old address, update your address before ordering the replacement. You can change your address online at Medicare.gov, by calling 1-800-MEDICARE, or through your local Social Security office.

If the card has already been mailed to the wrong address, call 1-800-MEDICARE and ask them to stop the mailing and reissue it to your current address. This adds a few extra days, but it's faster than waiting for the card to arrive at the old address and then having to request another one.

If you have a Medicare Advantage or Part D plan

If you're enrolled in a Medicare Advantage plan (like an HMO or PPO) or a prescription drug plan (Part D), you may have a separate insurance card from your plan in addition to your Medicare card. Losing your Medicare card doesn't affect your plan card, and you can still use your plan benefits with your plan card number.

However, some providers ask for your Medicare number as well as your plan number. While you're waiting for your Medicare card replacement, keep your plan card handy and have your Medicare number written down or saved in your phone.

If you've also lost your plan card, contact your plan directly — the phone number is usually on your Medicare statements or online account. Plan cards typically arrive within 7 to 10 business days as well.

Protecting your Medicare card going forward

Treat your Medicare card like you would a credit card. Keep it in a safe place at home, and carry it only when you have a medical appointment. Don't share your Medicare number with anyone except your doctor, hospital, pharmacy, or other healthcare provider you're actually seeing.

Scammers sometimes call or email claiming to be from Medicare and ask for your number. Medicare will never contact you first asking for personal information. If someone calls claiming to be from Medicare, hang up and call 1-800-MEDICARE yourself to verify.

If you travel, consider leaving your card at home and carrying a copy or writing down your number instead. This reduces the risk of losing it while you're away.
