CPT® Code 31624

The procedure described by CPT® Code 31624 involves the use of a bronchoscope, which can be either rigid or flexible, to perform a detailed examination of the airways and lungs. The bronchoscope is inserted through the nose or mouth and advanced into the oropharynx, allowing for a thorough visual inspection of this area. The vocal cords are also visualized during this process. Following the initial examination, the bronchoscope is further advanced into the trachea, where it continues to provide a view of the airway structure. The procedure allows for the examination of each mainstem bronchus, where any abnormalities can be identified and documented. In cases where a rigid bronchoscope is utilized, a telescope or flexible bronchoscope may be inserted through it to enhance visualization of the distal segments of the mainstem bronchi. A key component of this procedure is the bronchial alveolar lavage (BAL), which involves obtaining secretions from the lower respiratory tract. This is achieved by wedging the bronchoscope into the subsegmental bronchus that contains the lung lesion. In instances of diffuse lung disease, the bronchoscope is positioned in the right middle lobe bronchus. During the BAL, sterile normal saline is instilled through the bronchoscope and subsequently aspirated back into a specimen trap using suction, allowing for the collection of valuable diagnostic samples.
