Iowa Health System dba UnityPoint Health, the covered entity (CE), reported that multiple employees were the subjects of an email phishing scheme that compromised the protected health information (PHI) of 1,421,107 individuals. The PHI involved included names, dates of birth, Social Security and drivers’ license numbers, claims and financial information, diagnoses, lab results, medications, and other treatment information. The CE notified HHS, affected individuals, the media, and posted substitute notice on its website. In its mitigation efforts, the CE implemented additional administrative, technical, and security safeguards to better protect its sensitive data. All staff were retrained.
