Medicare Beneficiary Identifier (MBI)

The Iowa Department of Human Services (DHS) and Iowa Medicaid Enterprise (IME) issued a joint informational letter dated October 9, 2019 (I received it via email just this afternoon) that speaks to using the Medicare Beneficiary Identifier (MBI) on all claims.  Even though it’s issued by Iowa, it provides information that is relevant to all providers across the United States.  When you click on this hyperlink, you’ll find the PDF in the lower left corner.

The Centers for Medicare & Medicaid Services (CMS) is encouraging all Medicare providers to start transitioning from using a beneficiary’s Health Insurance Claim Number (HICN) to their MBI when submitting Medicare claims.

CMS has finished mailing new Medicare cards with a MBI to all beneficiaries and is encouraging beneficiaries to start using their new MBI to receive services. Using a MBI helps to protect the identities of people with Medicare and helps keep them safer from identity theft.

Beginning January 1, 2020, CMS will reject Medicare claims submitted with the HICN, with limited exceptions. CMS will reject all eligibility transactions submitted with the HICN.
