The Centers for Medicare & Medicaid Services have started to mail new Medicare cards. The cards will have a new Medicare number instead of your Social Security Number. This will help protect your identity and personal information. Your Medicare coverage and benefits will stay the same.
Medicare will automatically mail new cards at no cost to the address Social Security has on file for you. You can make sure your address up-to-date by using my Social Security. You can learn more about the new cards on the Medicare website.
If someone asks you for your information, for money, or threatens to cancel your health benefits if you don't share your personal information, hang up and call Medicare at 1-800-MEDICARE (1-800-633-4227).
