Airway sizing and insertion of bronchial valve(s) is a specialized procedure aimed at treating chronic obstructive pulmonary disease (COPD) with emphysema. The bronchial valves are designed to restrict airflow to the affected areas of the lung while still permitting the exit of air and mucus. This mechanism encourages atelectasis, or the collapse of the diseased lung regions, which can lead to significant improvements in pulmonary function, exercise capacity, quality of life, and overall life expectancy for patients suffering from this condition. The procedure involves the sizing of the airway and the insertion of the valves, which is typically performed during a bronchoscopy—a procedure that allows for direct visualization of the airways. During the procedure, a sizing device is introduced over a guidewire into the segmental or subsegmental bronchus to obtain precise measurements. Following this, a properly sized, collapsed one-way valve is advanced over the guidewire, and its position is confirmed using a bronchoscope. Adjustments are made as necessary to ensure optimal placement before the valve is deployed. Each lobe of the lung that receives one or more valves is reported separately using CPT® Code 0250T, which is applicable for each lobe treated during the procedure.
