This presentation summarizes the Texas EDI Corp's Off-The-Shelf Adjudication system called CATT. CATT can intake 837 claims, perform adjudication, and generate EDI responses. It allows setup of trading partner profiles, enrollment of new populations via 834 or 837, and adjudication of claims while being HIPAA compliant. CATT can read, validate, and convert 837 claim data and either adjudicate claims itself or receive adjudication files. It offers quick setup and centralized screens to help expedite claim processing.
