CMS (Centers for Medicare and Medicaid Services) is removing Social Security Numbers (SSN) also known as the HICN, from all Medicare ID cards by April 2019 and replacing the SSNs/HICN with a Medicare Beneficiary Identification Number (MBI). CMS will begin mailing the New Medicare ID cards in April and continue until sometime this summer.
CMS will use an MBI generator to assign 150 million Medicare Beneficiary Identification Numbers for active and deceased/archived beneficiaries, as well as generate a unique MBI for each new Medicare beneficiary. The new MBI numbers will replace the Social Security Number, thereby better protecting private health care and financial information, as well as Federal health care benefit and service payments.
CMS has announced that the first enrollees to get the new cards will be those in Delaware, Maryland, Pennsylvania, Virginia, West Virginia and the District of Columbia. The last enrollees to get the new cards later in the summer will be those in Kentucky, Louisiana, Michigan, Mississippi, Missouri, Ohio, Puerto Rico, Tennessee and the Virgin Islands.
CMS has granted a transition period that will end December 31, 2019. After the transition period ends, only MBIs will be accepted and transmitted.
What will the MBI look like?
