CPT® Code 43330

The procedure described by CPT® Code 43330 is known as esophagomyotomy, specifically of the Heller type, and is performed via an abdominal approach. This surgical intervention is primarily indicated for the treatment of esophageal achalasia, a condition characterized by the inability of the esophageal sphincter to relax properly. This dysfunction leads to uncoordinated contractions within the thoracic esophagus, resulting in significant difficulty swallowing (dysphagia) and a functional obstruction of the esophagus. The Heller myotomy aims to alleviate these symptoms by surgically cutting the muscle fibers of the lower esophageal sphincter, thereby allowing for improved passage of food from the esophagus into the stomach. The abdominal approach, also referred to as a transhiatal approach, involves making an incision in the upper abdomen to access the peritoneal cavity. This method allows for the mobilization of the stomach at the gastroesophageal junction and facilitates the exposure of the lower posterior mediastinum and distal esophagus, which are critical for the successful execution of the procedure.
