New Medicare ID Announced

To address the risk of medical identity theft, Section 501 of Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) mandates the removal of the Social Security Number (SSN)-based Health Insurance Claim Number (HICN) from Medicare ID cards.

The Centers for Medicare and Medicaid Services (CMS) uses HICN with multiple parties including Medicare providers and plans. Security for Medicare members should be strengthened by using an ID number that does not contain the member’s SSN.

Timing CMS will mail new Medicare ID cards from April 1, 2018 through April 1, 2019. The HICN, which contains the SSN, will be replaced with a Medicare Beneficiary Identifier (MBI).
