Elimination of SSN-based MBIs

December 05, 2019

As a reminder, the Centers for Medicare & Medicaid Services (CMS) has removed all Social Security Number (SSN)-based Health Insurance Claim Numbers (HICNs) from Medicare cards and are now using Medicare Beneficiary Identifiers (MBIs) for every Medicare member. Beginning January 1, 2020 you must use the Medicare Beneficiary Identifier (MBI) on all healthcare transactions. If you haven't begun to update your clients' accounts, now is the time.
