About 49446: Percutaneous gastrostomy-to-gastrojejunostomy conversion
Reports fluoroscopic conversion of an established gastrostomy into gastrojejunal access when post-pyloric tube delivery is needed through the existing tract.
This service converts an established percutaneous gastrostomy access into gastrojejunal access by passing a tube through the existing gastric tract and positioning its distal end in the small bowel under fluoroscopic guidance. It is typically performed by an interventional radiologist when post-pyloric delivery is needed, including when gastric feeding is not tolerated. Contrast injection and fluoroscopic confirmation of tube position are part of the documented procedure.
Report 49446 for conversion, rather than simply exchanging a G-J tube or replacing a G-tube with another gastric tube. Documentation should identify the existing gastrostomy, the conversion performed, relevant imaging or contrast findings, and the final tube position. The 0-day global period includes same-day preoperative and postoperative care. When another procedure in the same session is subject to the multiple procedure rule, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
