Protect your patients’ identities by using the Medicare Beneficiary Identifier (MBI) now. Starting January 1, 2020, you must use the Medicare Beneficiary Identifier (MBI). We will reject claims you submit with the Health Insurance Claim Number (HICN), with a few exceptions, and reject all eligibility transactions.
Don’t have an MBI?
·Ask your patients for their card. If they did not get a new card, give them the Get Your New Medicare Card flyer in English or Spanish.
·Use your Medicare Administrative Contractor’s look-up tool. Sign up for the Portal to use the tool.
·Check the remittance advice. Medicare returns the MBI on the remittance advice for every claim with a valid and active HICN.
