About this report

On May 22, 2018, the covered entity (CE), Contra Costa Health Plan, discovered that a business associate (BA) had provided services under a false identity.

The CE provided breach notification to HHS, affected individuals, and the media. OCR obtained assurances that the CE implemented the corrective actions listed above.
