EDI Audit Work Program

This audit work program focuses on the processes to set up, design, and test client and carrier interfaces, and understand the documentation that is maintained for each electronic data interchange (EDI) interface.

The work program evaluates the processes around data transmission and verifying the completeness and accuracy of the data that is transmitted. In addition, steps are included to confirm the controls in place successfully monitor the status of each interface, resolve processing errors as they occur, and review transmissions for fraudulent activity. It recommends conducting interviews and/or obtaining supporting documentation to identify the purpose of each in-scope interface and its impact.
