New Medicare Member ID Numbers Begin Rolling Out in April

The Centers for Medicare & Medicaid Services (CMS) will issue new Medicare ID numbers and ID cards to all Medicare beneficiaries between April 1, 2018, and April 1, 2019. CMS is removing the Social Security number-based Medicare ID, also known as a Health Insurance Claim Number (HICN), and replacing it with a new Medicare Beneficiary Identifier (MBI) number that does not contain a Social Security number (SSN) or other personal information. All Medicare ID cards will be replaced by April 2019. Until they receive the new Medicare ID card, Medicare beneficiaries are to continue using their current ID card.
