CMS Medicare Beneficiary Identifier Card

The Medicare Access and CHIP Reauthorization Act of 2015 requires CMS to remove Social Security Numbers from Medicare cards and, as a result, CMS is replacing the existing health insurance claim number with a Medicare Beneficiary Identifier (MBI). We will conduct a series of reviews to assess controls in place to distribute and implement usage of the MBI. We will (1) determine the number and nature of Medicare cards returned as undeliverable and the extent to which CMS tracks and follows up on Medicare cards returned as undeliverable, (2) assess CMS's safeguards in place to protect the MBI, and (3) conduct a review of payments to providers to determine whether Medicare cards deemed high risk and cards mailed and returned as undeliverable are being used for inappropriate items and services.
