The PHI involved included names, addresses, phone numbers, email addresses, dates of birth, Social Security numbers, diagnoses, drivers’ license/state identification numbers, and health insurance information. The BA notified affected individuals and the CE notified HHS, the media, and posted a substitute notice on its website. In its mitigation efforts, the CE and BA implemented additional administrative and technical safeguards. Ultimately, the CE terminated its business relationship with the BA.
