CPT® Code 43763

Replacement of gastrostomy tube, percutaneous, includes removal, when performed, without imaging or endoscopic guidance; requiring revision of gastrostomy tract

The procedure described by CPT® Code 43763 involves the replacement of a gastrostomy tube (GT) through a percutaneous approach. A gastrostomy tube is a flexible tube that is inserted through the abdominal wall into the stomach, primarily used for providing nutritional support, hydration, and medication to patients who cannot consume food or fluids orally. This procedure can be performed either as a routine replacement or as an emergency intervention in cases where the tube has been unintentionally dislodged. The process begins with the removal of the existing tube, which is achieved by deflating the balloon and applying gentle traction to extract the tube from the gastrocutaneous tract. Following the removal, the tract is inspected visually to ensure it is clear for the insertion of a new tube. The new gastrostomy tube is lubricated and carefully inserted through the ostium into the stomach, with placement confirmed through methods such as gastric content aspiration or air gurgle. If resistance is encountered during the insertion, minor revisions to the gastrostomy tract may be necessary, which can be performed without imaging or endoscopic guidance. This may involve dilating the tract to facilitate the reinsertion of the new tube. The procedure is crucial for maintaining the patient's nutritional needs and overall health when oral intake is not feasible.
