Transition to New Medicare Cards Begins April 1

Starting April 2018, the Centers for Medicare and Medicaid Services (CMS) will begin mailing new Medicare cards to all people with Medicare based on geographic location. North Carolina is part of the ‘fifth wave’ of mailings, which is set to begin after June. Learn more about the Mailing Strategy.  Starting April 2018, your patients will be able to check the status of card mailings in their area on

The new cards will have a new, unique Medicare Beneficiary Identifier (MBI) number, which will replace the current SSN-based Health Insurance Claim Number (HICN).

Beginning in October 2018, and throughout the transition period, which ends Dec. 31, 2019, when a practice submits a claim using a patient’s valid and active Health Insurance Claim Number (HICN), CMS will return both the HICN and the MBI on every remittance advice. During the transition period, CMS will monitor the use of HICNs and MBIs to make sure everyone will be ready to use only MBIs by January 2020. As of now, beginning Jan. 1, 2020, all Medicare claims (with a few exceptions) will need to be submitted using MBIs regardless of when you performed the service.
