Texas Health Arlington Memorial

Texas Health Arlington Memorial, the covered entity (CE), reported that a program coding error within its billing system allowed electronic protected health information (ePHI) to be mismatched with the incorrect account guarantor. This led to PHI being sent to the wrong recipients. This breach affected 6,187 individuals. The ePHI involved included names, health insurance information, and treatment information. The CE notified HHS, affected individuals, the media, and provided substitute notice on its website. In its mitigation efforts, the CE corrected the program coding error and implemented additional administrative and technical safeguards to prevent future incidents of this nature.
