CPT® Code 43216

Esophagoscopy is a medical procedure that involves the use of a flexible endoscope to visually examine the esophagus, which is the tube that connects the throat to the stomach. This procedure is performed transorally, meaning the endoscope is inserted through the mouth. During the esophagoscopy, the physician can assess various structures, including the velopharyngeal closure, the base of the tongue, and the hypopharynx. Vocal cord motion is also observed, and the pharyngeal musculature is evaluated for any abnormalities. The endoscope is carefully advanced through the esophagus until it reaches the gastroesophageal junction, allowing for a thorough examination of the entire length of the esophagus. In the context of CPT® Code 43216, the procedure specifically includes the removal of tumors, polyps, or other lesions using hot biopsy forceps. This technique involves the use of insulated monopolar forceps that not only excise the tissue but also cauterize it simultaneously, which helps to minimize bleeding. The hot biopsy method is particularly effective for small polyps and the treatment of vascular ectasias. This procedure is critical for diagnosing and treating various esophageal conditions, ensuring that any abnormal growths are addressed promptly and effectively.
