New Medicare Card: HICN Claims Reject January 1, 2020

Starting January 1, you must use Medicare Beneficiary Identifiers (MBIs) when billing Medicare 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 CMS Medicare Learning Network (MLN) Matters (MM) Special Edition (SE)18006 to learn how to get and use MBIs.
