The Mayo Clinic, the covered entity (CE), reported that an update to its mobile application software enabled users to access the electronic protected health information (ePHI) of 1,902 individuals. The ePHI involved included names, addresses, dates of birth, diagnoses, lab results, medications prescribed, and other treatment information. The CE notified HHS, affected individuals, the media, and posted substitute notice on its website. To fix this error, the CE revised its mobile application software.
