CMS Enrollment System Needs To Enhance Resiliency

The Centers for Medicare & Medicaid Services (CMS) Enrollment Database (EDB) is the primary source of Medicare enrollment information for the entire population of beneficiaries who have ever received Medicare benefits. Based on CMS officials’ estimates, we calculated the daily financial impact of a nonfunctional EDB to be approximately $47 million. Our objective was to determine whether CMS implemented security controls within the EDB to protect the confidentiality, integrity, and availability of Medicare enrollee data, in accordance with Federal requirements.
