CPT® Code 31646

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with therapeutic aspiration of tracheobronchial tree, subsequent, same hospital stay

A bronchoscopy is a medical procedure that involves the insertion of a bronchoscope, which can be either rigid or flexible, through the nose or mouth into the respiratory tract. This procedure allows for direct visualization of the airways, including the oropharynx, trachea, and bronchi. Fluoroscopic guidance may be utilized during the procedure to enhance the visualization of the structures being examined. The primary purpose of this procedure is to assess the condition of the tracheobronchial tree, identify any abnormalities, and perform therapeutic interventions as necessary. During the bronchoscopy, the vocal cords are also examined, and the bronchoscope is advanced into each mainstem bronchus to inspect for any irregularities. 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 bronchi. In cases where therapeutic aspiration is required, a suction catheter is introduced to the targeted area within the tracheobronchial tree to remove fluid or other substances. This specific code, CPT® 31646, is designated for subsequent therapeutic aspirations performed during the same hospital stay, following an initial aspiration coded as CPT® 31645.
