What?
Social Security numbers will be replaced with a new MBI (Medicare Beneficiary Number).

Why?
Protects private health care and financial information.

When?
Beginning in June 2018 or later, new Medicare cards will be mailed out to Illinois residents.

With the release of the Social Security Number Removal Initiative (SSNRI), Medicare members will be receiving new Medicare cards starting in June 2018 or later for Illinois residents. The new MBI should be protected just like a Social Security Number. You will be able to use either HICNs or MBIs to submit claims during the transition period. It will be a good time to test and make necessary adjustments. The transition period will be April 1, 2018 – December 31, 2019.
