The covered entity (CE), Mankato Clinic, reported that an employee accidentally sent an email containing the electronic protected health information (ePHI) of 535 individuals to the wrong recipient. The ePHI involved included names, addresses, dates of birth, financial information, and diagnoses/conditions. The CE notified HHS, affected individuals, the media, and provided substitute notice. In its mitigation efforts, the CE sanctioned the responsible employee and retrained staff on the importance of safeguarding ePHI.
