New Medicare Identification Card

Important Notice:  This information is for notification purposes only.  There is nothing you need to do. 


This notice is to inform you that beginning April 2018, you will receive a new Medicare Identification Card from the Centers for Medicare and Medicaid Services (CMS).

The Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 requires CMS to remove Social Security Numbers (SSNs) from all Medicare cards by April 2019. A new Medicare Beneficiary Identifier (MBI) will replace the SSN-based Health Insurance Claim Number (HICN) on the new Medicare cards for Medicare transactions like billing, eligibility status, and claim status.

Under the new system, each person enrolled in Medicare will be assigned a new MBI and mailed a new Medicare card.  The randomly generated MBI is confidential like the SSN and should be protected as Personally Identifiable Information.  CMS will issue new Medicare cards in phases by geographic location beginning April 2018.

Below is an example of what your new Medicare Card will look like.

During the transition period of April 1, 2018 through December 31, 2019 you can use either the HICN or the MBI to submit information to the Fund.  After the transition period ends on January 1, 2020, you’ll need to use the MBI on your submissions.

For questions regarding your new Medicare Identification Card or MBI, please contact CMS using the contact information on your existing Medicare Card.
