CPT® Code 31786

The procedure described by CPT® Code 31786 involves the excision of a tumor or carcinoma located in the distal third of the trachea. The trachea, commonly known as the windpipe, is a vital airway structure that connects the throat to the lungs. Tumors or carcinomas in this area can obstruct airflow and lead to serious respiratory issues. The excision is performed using either an anterior or posterior intrathoracic approach, depending on the specific location and characteristics of the tumor. In the anterior approach, a median sternotomy is performed, which involves making an incision along the sternum to gain access to the thoracic cavity. This allows for the retraction of major blood vessels to expose the trachea and carina, which is the point where the trachea divides into the left and right main bronchi. Alternatively, the posterior approach utilizes a right posterolateral thoracotomy, which involves an incision on the side of the chest to access the trachea from behind. This approach requires careful dissection of surrounding structures, including the esophagus and mediastinal pleura, to ensure that the vagus and laryngeal nerves are protected during the procedure. The excision of the tumor is performed with a margin of healthy tissue to ensure complete removal, followed by suturing of the trachea and closure of the surgical incisions. This procedure is critical for patients with tracheal tumors, as it aims to remove malignant growths and restore normal airway function.
