Centers for Medicare & Medicaid Services

The covered entity (CE), Centers for Medicare and Medicaid Services, reported that a software application used by its business associate (BA) exposed the protected health information (PHI) of 3,112,815 individuals. The PHI involved included names, dates of birth, addresses, Social Security numbers, claims and health insurance information, and other treatment information. The CE notified HHS, the media, and provided substitute notice; the CE and BA notified affected individuals. In response to the breach, the CE and BA implemented additional administrative and technical safeguards to better protect PHI.
