CPT® Code 43202

The CPT® Code 43202 refers to a flexible esophagoscopy procedure performed transorally, which includes the collection of tissue samples through biopsy, either single or multiple. This procedure utilizes a flexible endoscope, a thin, tube-like instrument equipped with a light and camera, allowing for a detailed examination of the esophagus. The endoscope is inserted through the mouth and carefully advanced into the esophagus, enabling the physician to visualize the velopharyngeal closure, base of the tongue, and hypopharynx. During the examination, vocal cord motion is assessed, and the pharyngeal musculature is evaluated for any abnormalities. 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, where any irregularities can be noted. After the examination, the endoscope is withdrawn, allowing for a thorough inspection of the esophagus's entire circumference. Tissue samples can be collected using biopsy forceps that are inserted through the endoscope's biopsy channel. The forceps are opened to capture the tissue, then closed to secure the sample before removal. This procedure is essential for diagnosing various esophageal conditions, as it allows for direct visualization and sampling of suspicious lesions or abnormalities within the esophagus.
