CPT® Code 43130

A diverticulectomy of the hypopharynx or esophagus, as described by CPT® Code 43130, is a surgical procedure aimed at removing a diverticulum, which is a sac-like pouch that can form in tubular organs such as the esophagus or hypopharynx. These diverticula can be either congenital, meaning 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 manifest in the middle or lower sections of the esophagus. The procedure can be performed via a cervical approach, which involves making an incision in the neck, usually on the left side, to access the affected area. During this approach, critical structures such as the internal jugular vein and carotid artery are carefully identified and retracted to provide visibility of the esophagus and/or hypopharynx. Alternatively, a thoracic approach may be utilized, which involves a right posterior thoracotomy to access the esophagus from within the thoracic cavity. Regardless of the approach, the goal of the diverticulectomy is to excise the diverticulum, which is characterized by a mucosal outpouching in the muscular wall, and to ensure the integrity of the surrounding structures while addressing any necessary myotomy to alleviate symptoms associated with the diverticulum.
