OCR description
The covered entity (CE), National Ambulatory Hernia Institute, was subject to a ransomware attack that affected the electronic protected health information (ePHI) of approximately 15,974 individuals. The ePHI involved included names, dates of birth, addresses, Social Security numbers, claims and financial information, diagnoses, lab results, and other treatment information. The CE notified HHS, affected individuals, the media, and posted substitute notice on its website. A toll-free number was provided to field questions. Following the ransomware attack, the CE implemented additional administrative, technical, and security safeguards to better protect its ePHI. OCR provided technical assistance to the CE and obtained assurances that the CE implemented the corrective actions noted.
