Centers for Medicare & Medicaid Services

The covered entity (CE), Centers for Medicare & Medicaid Services, reported that an employee of its business associate (BA) inadvertently mailed the protected health information (PHI) of 10,011 individuals to the wrong recipients. The PHI involved included names, addresses, claims information, diagnoses, and other treatment information. The CE notified HHS, affected individuals, the media, and provided substitute notice. In response to the breach, the BA implemented additional administrative and technical safeguards to better protect PHI.
