Rec. 1: The DoD OIG recommended that the Director of the Defense Health Agency work with the Program Executive Officer of the Program Executive Office, Defense Healthcare Management Systems to document and implement the process for identifying and collecting patient health data of DoD patients in the Military Health System in current and future registries within their purview in a written document, such as a standard operating procedure. The procedure should identify, at a minimum, the internal controls throughout the process, the relevant data sources, data fields, and diagnostic codes used in the computer scripts, and should be reviewed and approved when updates occur.
