Are Your Providers Using the MBI?

Starting January 1, 2020, Medicare will only accept claims and eligibility transaction submitted with the Medicare Beneficiary Identifier (MBI). Medicare will reject claims submitted with the Health Insurance Claim Number (HICN), with a few exceptions, and  all eligibility transactions. Work with your providers to be sure they are using MBIs for all Medicare business, including claims submission and eligibility transactions, to help protect the identity of people with Medicare. Share the MLN Matters Article  (PDF) about getting and using the MBI.
