CPT® Code 43220

Esophagoscopy, flexible, transoral, with transendoscopic balloon dilation (CPT® Code 43220) is a minimally invasive procedure that involves the use of a flexible endoscope to visualize the esophagus and perform dilation of a stricture. A stricture refers to a narrowing of the esophagus, which can impede the passage of food and liquids. This narrowing may arise from various conditions, including reflux esophagitis, which leads to inflammation and scarring; Schatzki's ring, a benign fibrous tissue formation; congenital esophageal atresia, a birth defect; or malignancies affecting the esophagus. During the procedure, the endoscope is inserted through the mouth and carefully advanced to the site of the stricture. A balloon catheter is then introduced through the endoscope's instrument channel and positioned at the stricture location. The balloon is inflated to a diameter of less than 30 mm, using a pressure gauge to monitor the inflation level. This inflation temporarily expands the esophagus at the site of the stricture, allowing for improved passage of food and liquids. The balloon is typically held in place for a brief period, ranging from 30 seconds to 2 minutes, before being deflated and removed. This procedure is essential for alleviating symptoms associated with esophageal strictures and improving the patient's quality of life.
