What 49450 covers
This service covers percutaneous replacement of an existing gastrostomy or cecostomy tube, with fluoroscopic guidance and contrast assessment to confirm tube position and function. It is commonly performed by an interventional radiologist in an imaging suite when a tube is dislodged, malfunctioning, or due for exchange. It is a replacement through an established tract, not creation of a new gastrostomy or cecostomy tract.
Report the code when documentation supports replacement of the existing tube and the imaging work associated with the exchange. The 0-day global includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
