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 HICNs with a few exceptions
• We will reject all eligibility transactions submitted with Health Insurance Claim Numbers (HICNs)

See the MLN Matters Article to learn how to get and use MBIs.
