Claims submitted without MBIs will be rejected, with some exceptions. The MBI replaces the social security number-based Health Insurance Claim Numbers (HICNs) from Medicare cards and is now used for Medicare transactions like billing, eligibility status and claim status.
Haven’t started submitting MBIs on your Medicare claims yet? Here’s what you need to do:
- Get MBIs from your patients and through the MAC portals (sign up) now and after the transition period. You can also find the MBI on the remittance advice. Medicare returns the MBI on the remittance advice for every claim with a valid and active HICN.
- Don’t wait for the Jan. 1 deadline to start using MBIs for Medicare transactions. Talk to your office staff and start today.
