Article Overview
This article explains how colonoscopy services are documented, reported, and paid when a procedure begins as diagnostic and becomes therapeutic during the same session. It is aimed at coders, billing staff, compliance teams, and clinical documentation reviewers who work with gastrointestinal endoscopy claims, Medicare rules, and related edit logic. The discussion focuses on how to interpret the procedure scenario, what records must be retained, and how payment is affected by bundled services, modifier use, and endoscopy payment rules.
Why This Topic Matters
Colonoscopy claims often involve overlapping diagnostic and therapeutic services, making accurate documentation and claim assembly important for correct reimbursement and compliance. Understanding the general billing framework helps prevent unbundling errors and reduces denials in Medicare endoscopy cases.
