"Via indwelling feeding tube, the stomach was insufflated with air. Under fluoroscopic guidance and 18 guage trocar, the stomach was percutaneously accessed. 7 French sheath was placed, and access to the esophagus was obtained in a retrograde direction with a wire and catheter. The wire was advanced out the patient’s mouth, and a 20 French Ponsky type gastrostomy tube was placed over the wire. The tube was guided through the patient’s mouth while performing gentle traction on the wire, resulting in advancement of the tube into the stomach. The gastrostomy tube disc expanded against stomach wall, and the gastrostomy tube exited the percutaneous tract." As the catheter was inserted via the mouth, would this still be supported by CPT code 49440?
