CPT® Code 31645

Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with therapeutic aspiration of tracheobronchial tree, initial

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 trachea and bronchi, to assess for any abnormalities. Fluoroscopic guidance may be utilized during the procedure to enhance visualization, although it is not always necessary. The primary purpose of this procedure is to examine the oropharynx, vocal cords, trachea, and mainstem bronchi for any signs of disease or obstruction. If any abnormalities are detected, the bronchoscope can be advanced to the specific site requiring intervention. A suction catheter is then employed to aspirate fluid from the tracheobronchial tree, which is essential for therapeutic purposes. The code 31645 is designated for the initial therapeutic aspiration performed during this procedure, while 31646 is used for any subsequent aspirations that may occur during the same hospital stay.
