New Medicare Cards

If you have Medicare, you can protect your identity and help prevent health care fraud by guarding your Medicare card like you would a credit card. Identity theft from stolen Medicare numbers is becoming more common. Medicare helped by removing Social Security numbers from Medicare cards and replacing them with a new, unique number for each person with Medicare. This decreases your vulnerability to identity theft.

Tips for Protecting Yourself

Here are some important steps you can take to protect yourself from the identity theft that can lead to health care fraud:

  • Don’t share or confirm your Medicare or Social Security number with anyone who contacts you by telephone, email, or in person, unless you’ve given them permission in advance. Medicare will NEVER contact you (unless you ask them to) to ask for your Medicare number or other personal information or to send you a new card. Medicare already has your information.
  • Don’t ever let anyone borrow or pay to use your Medicare number.
  • Review your Medicare Summary Notice (MSN) to be sure you and Medicare are only being charged for actual items and services received.

If someone calls you and asks for your Medicare number or other personal information, hang up and call 1-800-MEDICARE (1-800-633-4227) and your local Senior Medicare Patrol (SMP). To learn more about protecting yourself from identity theft and health care fraud, visit or contact your local SMP.
