CPT® Code 43773

Laparoscopy, surgical, gastric restrictive procedure; removal and replacement of adjustable gastric restrictive device component only

The procedure described by CPT® Code 43773 involves a laparoscopic surgical intervention specifically aimed at the removal and replacement of a component of an adjustable gastric restrictive device, commonly known as a gastric band. This type of surgery is typically indicated when there is a complication such as slippage of the gastric band, which can occur over time. The gastric band is designed to restrict the amount of food that can be consumed by creating a small pouch in the stomach, thereby aiding in weight loss for patients with obesity. During this procedure, a Veress needle is initially used to insufflate the abdomen, allowing for better visualization and access to the surgical site. Trocars are then introduced to facilitate the insertion of laparoscopic instruments. A nasogastric tube is also placed to decompress the stomach, ensuring that the surgical field is clear. The surgical team dissects the gastric band free from surrounding tissues, unlocks it, and repositions it as necessary. The replacement of the gastric band involves careful manipulation and adjustment to ensure proper placement and function. This procedure is distinct from other related codes, such as CPT® 43771, which involves a revision without replacement, and CPT® 43774, which includes the removal of both the gastric band and the subcutaneous port components. The meticulous nature of this laparoscopic approach allows for reduced recovery time and minimal invasiveness compared to open surgical techniques.
