New Medicare Card: Are You Using the MBI?

Many providers are using the new Medicare Beneficiary Identifier (MBI) for Medicare transactions. For the week ending January 25, providers submitted 62% of fee-for-service claims with the MBI. We encourage you to use MBIs now for all Medicare transactions. Don't have an MBI?

  • Ask your patient for their card. If they have not received a new card, ask them to look for a plain white envelope from the Department of Health and Human Services; sign into MyMedicare.gov to get their new number or print an official card; or call 1-800-Medicare (1-800-633-4227).
  • Use your Medicare Administrative Contractor's look up tool (Noridian Medicare Portal (NMP)) Look-up Tool. Sign up (Register) for the portal
  • Check the Remittance Advice. We return the MBI on the remittance advice for every claim with a valid and active Health Insurance Claim Number.
