CPT® Code 43635

Add-On Code

The procedure described by CPT® Code 43635 involves a surgical intervention known as vagotomy, which is performed in conjunction with a partial distal gastrectomy. The vagus nerve, identified as the tenth cranial nerve, plays a crucial role in the autonomic regulation of the gastrointestinal tract. It originates from the brainstem and extends through the neck, thorax, and abdomen, branching out to innervate various parts of the stomach and upper digestive system. The primary purpose of performing a vagotomy is to reduce the production of gastric acid, which can help in the prevention of peptic ulcers. Historically, vagotomy was a common surgical approach for managing ulcers; however, its frequency has diminished significantly due to the effectiveness of pharmacological treatments available today. During the procedure, the vagus nerve is carefully identified and separated from adjacent structures, followed by the division of the main vagal nerve trunks to achieve the desired therapeutic effect.
