The Centers for Medicare and Medicaid Services (CMS) recently unveiled the newly designed Medicare card,  which will contain the unique, randomly assigned Medicare Beneficiary  Identification (MBI) number replacing the current Social Security-based  number. 
CMS will begin mailing the new cards to people with  Medicare benefits in April 2018, with the deadline for replacing all  existing Medicare cards by April 2019 as required under the Medicare  Access and CHIP Reauthorization Act of 2015 (MACRA). CMS will allow a  21-month transition period beginning no sooner than April 2018, where  health care providers will be able to use either the patient’s current  Medicare number or the patient’s new Medicare number.
CMS has developed a new web page to help physicians navigate the transition to the new MBI number,  including a recently developed resource on how to talk to your Medicare  patients about the new Medicare card. Physicians should also talk to  their practice managers and health IT vendors now to ensure their  systems will be ready to accept the MBI.
