medicare, medicare enrollment, medicare part dThe Centers for Medicare & Medicaid Services (CMS) recently began removing the Social Security Number (SSN)-based Health Insurance Claim Number (HICN) from Medicare ID cards to help prevent fraud and fight identity theft. The new Medicare Beneficiary Identifier (MBI) is a combination of uppercase letters and numbers.

  • The MBI has 11 characters
  • The characters in the positions 2, 5, 8, and 9 will always be alphabetic
  • Example: 2A22A22AA22
  • All letters are UPPERCASE
  • In an effort to reduce confusion, the MBI will never include the following letters:
  • S, L, O, I, B, Z (as these letters are frequently mistaken for certain numbers)
 Medicare beneficiaries will be receiving their new Medicare ID cards between April 2018 and April 2019 with their new MBI. It will take some time for CMS to mail everyone a new card. Your card might arrive at a different time than your friend’s or your neighbor’s card. We would appreciate if you would let us know your new Medicare ID Number as it is important for our records here at Health Insurance Solutions.

 Watch out for Medicare scams! 

Medicare will never call you uninvited and ask you to give them personal or private information to get your new Medicare Number and card.
Scam artists may try to get personal information (like your current Medicare Number) by contacting you about your new card. 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 us at 1-800-MEDICARE (1-800-633-4227).
Your new card will have a new Medicare Number that’s unique to you, instead of your Social Security Number.
