New Medicare ID Cards Start Arriving in April
CMS 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 healthcare and financial information, as well as Federal health care benefit and service payments.
