CPT® Code 31770

A bronchoplasty is a surgical procedure aimed at repairing the bronchus, which is the airway that leads from the trachea to the lungs. The specific procedure described by CPT® Code 31770 involves the use of a graft to repair the bronchus. This is typically indicated in cases where there is damage or a defect in the bronchial structure that requires surgical intervention. The procedure begins with an anterior intercostal incision, which is extended around the chest to the scapula, allowing for adequate exposure of the lung and bronchus. A rib spreader may be utilized to facilitate access, and in some instances, a rib may be removed to enhance visibility and access to the bronchus. Once the lung is deflated, the bronchus is carefully exposed for repair. The graft repair often employs a pericardial patch, which is a section of the pericardium, the membrane surrounding the heart. This patch is excised, treated with glutaraldehyde solution for preservation, and then configured to fit the defect in the bronchus. The procedure requires meticulous attention to detail, including the identification and protection of the phrenic nerve, which is crucial for diaphragm function. The graft is then sutured to the bronchial defect, and the pericardial site is closed. This procedure is critical for restoring airway integrity and function, ensuring that the patient can breathe effectively post-surgery.
