New Medicare Cards Rolling out now – the MBI and Your Practice

Example of the new Medicare cards.

Example of the new Medicare cards.

The Centers for Medicare & Medicaid Services (CMS) are removing Social Security Numbers from Medicare cards to prevent fraud, fight identity theft, and keep taxpayer dollars safe.

CMS has started mailing newly-designed Medicare cards with the new Medicare Beneficiary Identifier (MBI), or Medicare Number. People enrolling in Medicare for the first time will be among the first to get the new cards. Current Medicare beneficiaries will receive their new cards in phases by geographic location from April 2018 through April 2019. CMS will keep accepting the Health Insurance Claim Number (HICN) through the transition period, which ends December 31, 2019.

Please request new cards from your patients and make sure you have the most updated insurance cards and MBI (Medicare Beneficiary Identifier).

The MBI will be:

  • Clearly different than the HICN and RRB number
  • 11-characters in length
  • Made up only of numbers and uppercase letters

For additional information, please refer to the link:

Please note that if a Plan submits a Health Insurance Claim Number (HICN) instead of an MBI after the transition period ends on January 1, 2020, claims will be rejected with the exception of certain areas such as appeals, adjustments, and some reporting.
