HICN Claims Reject
We are 50 days out from the end of the Medicare Beneficiary Identifier (MBI) transition period. Use the MBI on Medicare claims and other transactions now. Starting January 1, regardless of the date of service:
- We will reject claims submitted with Health Insurance Claim Numbers (HICNs) with a few exceptions
- We will reject all eligibility transactions submitted with HICNs
See the MLN Matters Article to learn how to get and use MBIs.
