CMS is Encouraging Providers to Submit Claims with MBI

CMS is encouraging providers to use the new Medicare Beneficiary Identifier (MBI) for all Medicare transactions. According to CMS, for the week ending March 1, providers submitted 67% of fee-for-service claims with the MBI. Below are 3 ways to obtain the MBI:

  • Ask your patient for their card. If your Medicare patients say they did not get a card, instruct them to call 1-800-MEDICARE to obtain a new card.
  • Use your Medicare Administrative Contractor’s look up tool. Sign up for the Portal to use the tool.
  • Check the remittance advice. CMS returns the MBI on the remittance advice for every claim with a valid and active Health Insurance Claim Number.
