CPT® Code 43762

Replacement of gastrostomy tube, percutaneous, includes removal, when performed, without imaging or endoscopic guidance; not requiring revision of gastrostomy tract

The procedure described by CPT® Code 43762 involves the replacement of a gastrostomy tube (GT) through a percutaneous approach. A gastrostomy tube is a flexible catheter that is inserted through the abdominal wall into the stomach, primarily used for 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 become dislodged unexpectedly. The replacement process begins with the removal of the existing tube, which is achieved by deflating the balloon and applying gentle traction while stabilizing the abdomen. Once the tube is removed, the gastrocutaneous tract is inspected visually to ensure it is clear and free of complications. A new tube is then lubricated and inserted through the ostium into the stomach, with confirmation of proper placement achieved through methods such as gastric content aspiration or air gurgle. In cases where the new tube does not pass easily, minor revisions to the gastrostomy tract may be performed without the need for imaging or endoscopic guidance. This may involve dilating the tract using simple instruments to facilitate the reinsertion of the new tube. The procedure is designed to ensure that patients continue to receive necessary nutritional support, hydration, and medication administration effectively.
