What G0500 covers
G0500 represents the endoscopist’s moderate sedation service during a gastrointestinal endoscopy, such as colonoscopy or upper endoscopy. The physician or other qualified health care professional performing the endoscopy also provides the sedation, with an independent trained observer assisting in monitoring the patient’s consciousness and physiologic status. The service covers the initial 15 minutes of intra-service time for patients age five or older.
Report G0500 with the endoscopic procedure when the endoscopist provides qualifying moderate sedation; it is not the code for anesthesia furnished by a separate anesthesia professional. The record should support the sedation provided, the observer’s monitoring role, the patient’s age, and the intra-service time. For additional qualifying sedation time, 99153 may be reported for each additional 15-minute interval when supported. CMS assigns G0500 separate physician fee schedule values for office and facility settings, with different practice-expense values by setting.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
