Transition Period for New Medicare Cards Ends in 5 Months!

August 6, 2019

Starting Jan. 1, 2020, Medicare claims must be submitted using the Medicare Beneficiary Identifier (MBI) regardless of what date the service was performed. If you submit a claim using the old Health Insurance Claim Number (HICN), which is based on the individual’s social security number, CMS will reject the claim, with few exceptions.

The MBI is a unique, randomly-selected 11-digit number using alpha and numeric characters that is replacing the HICN.

You may continue to accept both the old (HICN) and new (MBI) Medicare cards from patients during the transition period, which ends Dec. 31, 2019.

Starting Jan. 1, 2020, CMS will only accept claims using the MBI.
