What 43191 covers

An otolaryngologist or other qualified physician passes a rigid endoscope through the mouth to inspect the esophagus for problems such as dysphagia, suspected mucosal abnormality, or narrowing. The service is commonly performed in a procedural or operating-room setting. Brushing or washing to collect specimens is included when performed; this code describes diagnostic examination rather than endoscopic biopsy or treatment such as foreign-body removal.

Select this code when the documented approach is rigid and transoral and the service is diagnostic. The operative or procedure note should identify the route and instrument, the area examined, and any brushing or washing performed. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Medicare does not pay an assistant-at-surgery claim for this service; co-surgeon and team-surgery billing are not permitted.

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.
