The covered entity (CE), University of Missouri Health Care, reported that an employee was the victim of an email phishing scheme that affected the protected health information (PHI) of 189,736 individuals. The PHI involved included names, addresses, dates of birth, drivers’ license and Social Security numbers, diagnoses, lab results, medications prescribed, and health insurance and other treatment information. The CE notified HHS, affected individuals, the media, and posted substitute notice on its website. A call center was established for questions or concerns. In its mitigation efforts, the CE provided complimentary credit monitoring services and implemented additional administrative and technical safeguards to better protect its PHI. Staff were retrained on email security.
