CPT® Code 31760

An intrathoracic tracheoplasty, designated by CPT® Code 31760, is a surgical procedure aimed at repairing defects located in the distal third of the trachea. This operation is critical for restoring the integrity and function of the trachea, which is essential for normal respiratory function. The specific approach taken during the procedure—either anterior or posterior—depends on the location and nature of the defect being addressed. In the anterior approach, a median sternotomy is performed, allowing access to the trachea by incising the anterior pericardium and retracting surrounding blood vessels to create a clear surgical field. Conversely, the posterior approach involves a right posterolateral thoracotomy, which entails dissecting the posterior mediastinal pleura and mobilizing the esophagus to gain access to the trachea. Throughout the procedure, careful attention is paid to protect critical structures such as the vagus and laryngeal nerves. Once the trachea is adequately exposed, the surgeon identifies the defect, which may involve incising the trachea if the defect is within the tracheal lumen. The repair may involve excising tracheal tissue and closing the defect with a patch or graft, potentially reinforced with a muscle flap or other tissue. The procedure concludes with the closure of the surgical incisions, ensuring that the patient can begin the recovery process.
