A: Yes, but not right away. Social Security numbers will be removed from Medicare cards starting in April 2018. This change is designed to protect private health care and financial information tied to Social Security numbers.
People who qualify for Medicare in April 2018 (and beyond) will have new Medicare Beneficiary Identifiers (MBIs) on their red-white and blue Medicare cards. The new numbers will be 11 characters long instead of the nine numbers and one letter that are used today. Those that started Medicare prior to April 2018 will be issued a new MBI- based Medicare card as well.
There will be a transition period for the changeover. During this time, April 2018 through December 2019, providers will accept both the SSN and MBI based Medicare cards.
