CPT® Code 31637

Add-On Code

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; each additional major bronchus stented (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 31637 involves the use of a bronchoscope, which can be either rigid or flexible, to perform a detailed examination and intervention within the airways. The bronchoscope is inserted through the patient's nose or mouth and navigated into the oropharynx, allowing for a thorough visual assessment of the vocal cords and the trachea. This examination is crucial for identifying any abnormalities within the airways. The bronchoscope is then advanced into each mainstem bronchus, where further evaluation occurs. In cases where there is an obstruction or stenosis, the procedure may involve the use of a balloon catheter to dilate the affected area before the placement of a bronchial stent. This stent is designed to maintain airway patency by being positioned within the obstructed or narrowed lumen. The use of fluoroscopic guidance during this procedure enhances the accuracy of stent placement. It is important to note that CPT® Code 31637 is specifically used to report each additional major bronchus that is stented, in addition to the primary procedure code for bronchoscopy.
