About this report

The covered entity (CE), Walgreens, sent an improperly formatted survey letter to individuals so that protected health information (PHI) was visible in the addressee window of the envelope. The visible PHI included recent prescription histories, clinical, and demographic data affecting 4,500 individuals in 49 states. Following the breach, the CE conducted an investigation to determine the root cause of the breach, revised quality control steps for mailings that contain PHI, and retrained department staff on its revised procedures. The CE provided breach notification to HHS, affected individuals, and the media and posted a substitute notice on the home page of its website. OCR obtained documented assurances that the CE implemented the corrective actions noted above.
