CPT® Code 43200

Esophagoscopy, flexible, transoral; diagnostic, including collection of specimen(s) by brushing or washing, when performed (separate procedure)

The CPT® Code 43200 refers to a flexible transoral esophagoscopy performed for diagnostic purposes. This procedure involves the use of a flexible endoscope, which is a thin, tube-like instrument equipped with a light and camera, allowing for visualization of the esophagus. The endoscope is introduced through the mouth and carefully advanced into the esophagus, enabling the physician to examine various anatomical structures, including the velopharyngeal closure, base of the tongue, and hypopharynx. During the procedure, the physician observes vocal cord motion and evaluates the pharyngeal musculature. As the endoscope reaches the cricopharyngeus, the patient may be instructed to burp or swallow to facilitate the passage of the scope. The endoscope is then advanced along the entire length of the esophagus until it reaches the gastroesophageal junction. Any abnormalities detected during the examination are noted for further evaluation. Additionally, the procedure may include the collection of specimens through brushing or washing techniques. This involves the introduction of saline fluid into the esophagus, which is then collected along with any cellular material for diagnostic analysis. It is important to note that this code is designated as a separate procedure, meaning it is reported independently when performed without any additional therapeutic interventions. The flexibility of the endoscope allows for a comprehensive assessment of the esophagus, making it a valuable tool in diagnosing various esophageal conditions.
