CMS Transition of Patient Identiﬁers from HICN to MBI
CMS to end use of Social Security numbers on Medicare cards
As a component of the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA), the Centers for Medicare & Medicaid Services (CMS) is removing Social Security numbers from Medicare cards. The goals are to reduce the risk of identity theft for beneﬁciaries and the number of fraudulent claims made to Medicare.
The New Medicare Card project (formerly known as the Social Security Number Removal Initiative) requires eligibility and claims processing software, electronic health records, and payer systems to use randomly generated Medicare Beneﬁciary Identiﬁers (MBIs.) Medicare cards have been transitioning to MBIs over a one-year period that began April 1, 2018. By December 31st, 2019 all HICNs will be also be changed to MBIs.

Frequently Asked Questions
Does New Medicare Card project apply to both traditional Medicare and Medicare Advantage?
Yes. Beneﬁciaries in both types of plans will be assigned MBIs, however Medicare Advantage and prescription drug beneficiaries may still have health plan member IDs assigned and visible on their cards.
Is it true that archived and deceased beneﬁciaries will also be assigned MBIs?
Yes, more than 90 million deceased beneﬁciaries will receive new numbers. This will not impact providers and payers.
How will this affect Medicare beneficiaries?
The MBI won’t change Medicare eligibility or beneﬁts. Medicare beneﬁciaries should begin using their new Medicare cards and the MBI as soon as they receive them.
