Validation of the American Society for Gastrointestinal Endoscopy’s Complexity Grading System for Endoscopic Procedures (Clinical and Translational Gastroenterology )

A new validation study of the American Society for Gastrointestinal Endoscopy (ASGE) complexity grading system confirms something clinicians intuitively know: not all endoscopic procedures are created equal. For procedures like EGD, colonoscopy, and EUS, the grading system shows strong correlation with both physician effort (wRVUs) and medicolegal risk (mRVUs)—suggesting it is a reliable framework for measuring procedural difficulty.
