New Medicare Beneficiary Identifier (MBI) Get It, Use It - Reissued

MLN Matters Number: SE18006 Reissued
Article Release Date: August 19, 2019

Note: CMS reissued this article on August 19, 2019, to show that all new Medicare cards have been mailed, to encourage providers to use MBIs now to protect patients' identities, to emphasize that providers must use MBIs beginning January 1, 2020, and to explain the rejection codes providers will get if they submit a HICN after January 1, 2020.

Use MBIs now for all Medicare transactions. The Centers for Medicare & Medicaid Services (CMS) finished mailing new Medicare cards. The new cards without Social Security Numbers (SSNs) offer better identity protection. Help protect your patients' personal identities by getting their MBIs and using them for Medicare business, including claims submission and eligibility transactions.
