The Centers for Medicare & Medicaid Services (CMS) is in the process of issuing new Medicare Beneficiary Identifiers and Medicare cards to help protect the identities of Medicare beneficiaries. The Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 requires CMS to remove beneficiaries’ Social Security Numbers (SSNs) from Medicare cards by April 2019 to mitigate risk of medical identity theft. CMS will begin mailing new Medicare cards to beneficiaries in April 2018. The cards will be mailed in seven waves by groups of states over the next year. New York is in the fourth wave. New cards will be mailed out after June 2018. All beneficiaries should receive a new card by April 2019.
