CPT® Code 43249

Esophagogastroduodenoscopy, flexible, transoral; with transendoscopic balloon dilation of esophagus (less than 30 mm diameter)

The procedure described by CPT® Code 43249 involves a flexible esophagogastroduodenoscopy (EGD) performed transorally, which allows for a comprehensive examination of the upper gastrointestinal (UGI) tract, specifically the esophagus, stomach, duodenum, and/or jejunum. This procedure includes a specialized technique known as transendoscopic balloon dilation of the esophagus, utilizing a balloon with a diameter of less than 30 mm. The primary purpose of this dilation is to treat esophageal strictures, which are abnormal narrowing of the esophagus that can occur due to various conditions. These conditions may include reflux esophagitis, which leads to inflammation and scarring; Schatzki's ring, a benign fibrous tissue formation; congenital esophageal atresia; or malignancies affecting the esophagus. During the procedure, the patient is prepared by numbing the mouth and throat with an anesthetic spray, followed by the placement of a hollow mouthpiece to facilitate the insertion of the endoscope. The flexible fiberoptic endoscope is then carefully advanced through the mouth and into the esophagus, guided by the patient's swallowing reflex. Once the endoscope reaches the area of stricture, the dilation process begins. This may involve the use of a guidewire and a series of dilators or, as specified in this code, a balloon catheter that is inflated to widen the narrowed area. The inflation is monitored using a pressure gauge to ensure optimal dilation, and the balloon is held in place for a brief period before being deflated and removed. After dilation, the endoscope allows for direct visualization of the treated area to confirm the success of the procedure and to check for any potential injuries to the esophagus. The examination may extend into the stomach, duodenum, and/or jejunum to assess these areas as well.
