The Centers for Medicare & Medicaid Services (CMS) is removing Social Security numbers from Medicare cards. This package includes important information about our work to assign new identification numbers and issue new Medicare cards to all people with Medicare beginning in April 2018.
They Are replacing the current Health Insurance Claim ID Numbers with a unique, randomly generated number on the new Medicare cards. Your Medicare patients usually call this their “Medicare number.” In Their official guidance and documents to you, they’ll refer to this new Medicare number as the Medicare Beneficiary Identifier or MBI.
They Are moving to new Medicare cards and numbers are to make sure your Medicare patients have continuous access to care and you have the tools and information you need to make the change. You’ll be able to look up your Medicare patient’s new Medicare number through your Medicare Administrative Contractor’s (MAC’s) secure web portal starting in June 2018.
