New Medicare Card: MBI on Remittance Advice October 1

For Remittance Advices generated after October 1 through the end of the transition period, CMS will return both the new Medicare Beneficiary Identifier (MBI) and Health Insurance Claim Number (HICN) when you submit a claim with a valid and active HICN. We will report the MBI in the same place you get the "changed HICN" today. Providers can also get the MBI by asking patients for their new Medicare card or using your Medicare Administrative Contractor's MBI look up tool through their portal; sign up for the Noridian Medicare Portal (NMP) if you do not have access.

To ensure Medicare patients continue to get care, you can use either the HICN or MBI for all Medicare transactions through December 31, 2019.
