Many providers are using the new Medicare Beneficiary Identifier (MBI) for Medicare transactions. For the week ending Jan. 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. Sign up for the Portal to use the tool.
Check the remittance advice. We return the MBI on the remittance advice for every claim with a valid and active Health Insurance Claim Number.
