Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with injection of contrast material for segmental bronchography (fiberscope only)

The procedure described by CPT® Code 31656 involves the use of a bronchoscope, which can be either rigid or flexible, to perform a detailed examination of the airways. The bronchoscope is inserted through the nose or mouth and is carefully advanced into the oropharynx, allowing for a thorough visual inspection of the area. Fluoroscopic guidance may be utilized during the procedure to enhance visualization and accuracy. The examination includes the vocal cords and extends into the trachea, where any abnormalities can be identified. The bronchoscope is further advanced into each mainstem bronchus, which are the primary branches of the trachea leading to the lungs. If a rigid bronchoscope is employed, a telescope or flexible bronchoscope can be inserted through it to provide a clearer view of the distal segments of the mainstem bronchi. A catheter is then introduced, and a radiopaque dye is injected to facilitate the visualization of the segmental bronchi. These segmental bronchi are the smaller branches that arise from the lobar bronchi, which are the secondary divisions of the right and left mainstem bronchi, and they supply specific bronchopulmonary segments within the lungs. Typically, the right lung contains ten segmental bronchi, while the left lung has nine, each serving distinct areas of lung tissue.
