CPT® Code 31781

The procedure described by CPT® Code 31781 involves the excision of tracheal stenosis and subsequent anastomosis, specifically utilizing a cervicothoracic approach. Tracheal stenosis refers to the narrowing of the trachea, which can lead to significant respiratory difficulties. In this procedure, the stenotic segment of the trachea is surgically removed, and the remaining proximal and distal segments are then reconnected, or anastomosed, to restore normal airflow. This code is specifically used when the stenosis extends into the distal third of the trachea, necessitating a more invasive surgical approach compared to procedures that address stenosis located in the proximal or middle thirds of the trachea. The cervicothoracic approach allows for adequate exposure of the trachea, which is essential for the successful excision of the narrowed segment and the subsequent reconstruction of the airway. The procedure may also involve additional techniques, such as sliding tracheoplasty, to optimize the airway's diameter and functionality. Overall, CPT® Code 31781 captures a complex surgical intervention aimed at alleviating airway obstruction caused by tracheal stenosis.
