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.
Many providers are using the MBI for Medicare transactions. For the week ending August 2, providers submitted 77% of fee-for-service claims with the MBI. Protect your patients’ identities by using MBIs now for all Medicare transactions. Don’t have an MBI?
Ask your patient 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. We return the MBI on the remittance advice for every claim with a valid and active HICN.
