Instead, the new cards will feature a randomly assigned Medicare beneficiary identifier (MIB). The MBI will be generated from randomly selected numbers. The characters will have no special meaning. Other changes include the removal of the cardholder’s gender and the signature line.
The new Medicare cards are due to the signing of the Medicare Access and CHIP Reauthorization Act of 2015. This represents a major effort by the Centers for Medicare and Medicaid Services (CMS) to fight fraud against seniors.
