CPT® Code 42950

A pharyngoplasty, designated by CPT® Code 42950, is a surgical procedure that involves plastic or reconstructive operations on the pharynx, which is the muscular tube that connects the nasal cavity to the esophagus. This procedure is essential for addressing various defects or malformations of the pharynx, which may arise from congenital issues, trauma, or disease. The surgery typically begins with an incision made in the skin of the neck, often utilizing an apron-type incision located within the natural skin folds or a vertical incision positioned anterior to the sternocleidomastoid muscles. This approach allows for adequate exposure of the pharynx by retracting the sternocleidomastoid muscles laterally and rotating the strap muscles and larynx medially. Once the pharynx is accessible, the surgeon dissects the tissue plane located behind the pharynx and in front of the cervical spine, exposing the posterior aspect of the pharynx for thorough inspection. This inspection is crucial for determining the specific type and extent of the reconstructive procedure required. The surgical site is then flushed with sterile saline to eliminate any debris, and any necrotic tissue is carefully debrided to promote healing. The edges of any pharyngeal injuries are trimmed to facilitate a clean repair. In the context of CPT® Code 42950, the primary focus is on the repair of the pharynx itself. If reconstruction of the oropharynx or hypopharynx is necessary, a dynamic, sensate local flap is utilized to ensure that swallowing function is preserved and the risk of aspiration is minimized. The surgeon selects an appropriate donor site for the myocutaneous or other tissue flap, which is developed as part of a separately reportable procedure. This flap is then sutured over the pharyngeal defect to restore the integrity of the pharyngeal structure. Overall, the pharyngoplasty procedure is a complex and delicate operation aimed at restoring normal function and anatomy to the pharynx.
