On December 31, 2011, the names, dates of birth, medical record numbers, and clinic notes for 750 of the covered entity’s (CE) patients were available on its network server and website. The CE disabled the website and removed the 750 patients’ demographic and clinical information from its network server. The CE provided breach notification to HHS, affected individuals, and the media. As a result of OCR’s investigation, the CE provided fraud and credit monitoring to affected individuals and retrained its staff on technical safeguards.
