New Medicare Beneficiary Identifier (MBI) Get It, Use It - Revised
MLN Matters Number: SE18006 Revised
Article Release Date: March 19, 2020
Note: CMS revised the article on March 19, 2020, to clarify that you need the beneficiary’s first name, last name, date of birth, and SSN to use MBI look-up tool. All other information remains the same.
Use MBIs for all Medicare transactions. The Centers for Medicare & Medicaid Services (CMS) replaced the Social Security Number (SSN)-based Health Insurance Claim Numbers (HICNs) with the MBI and mailed new Medicare cards to all Medicare beneficiaries. The cards with MBIs offer better identity protection.
