Reading AAA rejections well is a core intake skill: the loop location tells you whose data failed (subscriber, patient, provider, UMO), the reason code tells you what failed, and the follow-up action code tells you whether to correct, resubmit, or call. Rejection analytics built on AAA data drive most intake-quality improvement programs.
