What 49465 covers
A physician, commonly a radiologist, evaluates an indwelling gastrostomy, duodenostomy, jejunostomy, gastrojejunostomy, or colostomy tube by injecting contrast through it and observing the flow under fluoroscopy. The study can help assess tube position, patency, or suspected leakage. It is performed in a radiology department or another setting equipped for fluoroscopic imaging when the clinical question calls for a contrast examination of the existing tube.
Report 49465 for the fluoroscopic examination, including the contrast injection or injections, image documentation, and report. The record should identify the tube examined, the reason for the study, the contrast findings, and the interpretation. This is a diagnostic examination, not a tube replacement or repositioning service. It has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
