As a reminder, the Centers for Medicare & Medicaid Services (CMS) is issuing new Medicare ID numbers and ID cards to all Medicare beneficiaries. 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 cards will be replaced by April 2019. Until they receive the new Medicare ID card, Medicare beneficiaries should continue using their current ID card.

The new Medicare cards will be mailed to beneficiaries in waves between April 1, 2018, and April 1, 2019. The tentative schedule from CMS is:
