The covered entity (CE) was the victim of a malware/ransom attack affecting the protected health information (PHI) of 266,123 patients. The PHI involved in the breach included names, dates of birth, addresses, social security numbers, driver’s license information, claims information, and treatment information such as diagnoses, medications, lab results, and medical images. The CE provided breach notification to HHS, affected individuals, and the media. Following the breach, the CE strengthened its administrative and technical safeguards. OCR’s investigation resulted in the CE enhancing its practices in safeguarding PHI.
