New Medicare cards

Medicare Beneficiary Identifiers (MBIs)

The Medicare Access and CHIP Reauthorization Act of 2015 required us to remove Social Security Numbers (SSNs) from all Medicare cards.

There's a transition period that will go through December 31, 2019, where you can use either the HICN or the MBI to exchange data with us. Starting January 1, 2020, you must submit claims using MBIs (with a few exceptions), no matter what date you performed the service.

How can you help people with Medicare with their MBIs?

Check our Outreach & education page to get information for you and resources you can use when you talk to people with Medicare about their MBIs.
