Medical Practice Concepts, Inc., a business associate (BA) that provides the covered entity (CE), Prima Medical Foundation, with business and health care system services, experienced a ransomware infection. A third party forensic firm hired to investigate this incident found no evidence that protected health information was accessed, viewed, or transferred. However, the BA informed the CE that during the data restoration process one of their backup systems failed, causing the loss of certain information documented by the CE's physicians during the period from July 11, 2016 through July 26, 2016. OCR has consolidated the review of this case into a review of the BA.
