CPT® Code 43135

A diverticulectomy of the hypopharynx or esophagus is a surgical procedure aimed at removing a diverticulum, which is an abnormal sac or pouch that can form in the wall of these tubular organs. Diverticula can be either congenital, present at birth, or acquired due to various factors. One common type of acquired diverticulum in the hypopharynx is known as a Zenker diverticulum, which occurs when the mucosal lining herniates through a weak area in the posterior wall of the hypopharynx. While diverticula in the esophagus are less common, they typically develop in the middle or lower sections of the esophagus. The procedure can be performed using different surgical approaches, with the thoracic approach being utilized in this specific code (CPT® 43135). This approach involves accessing the esophagus through a right posterior thoracotomy, which allows for direct visualization and manipulation of the diverticulum. The surgical technique requires careful dissection and mobilization of the esophagus or hypopharynx to ensure complete excision of the diverticulum, which is characterized by a mucosal outpouching in the muscular wall. The procedure may also include a myotomy, which is the surgical incision of the muscle, performed on the side opposite to the diverticulum to alleviate any associated symptoms or complications.
