OCR description

The covered entity (CE) mistakenly included protected health information in two postcard mailings affecting 2,063 individuals. The first mailing included the CE’s patients and second mailing included the patients of other CEs for which the CE acted as the business associate (BA). The PHI involved in the breaches included names, home addresses, and an eleven-digit number (social security number plus two digits). The CE provided breach notification to HHS, affected individuals, and the media. Following the breach, the CE revised mailing procedures, retrained applicable staff, and sanctioned the involved employee. OCR obtained documented assurances that the CE/BA implemented the corrective actions listed above.
