CPT® Code 31375

A partial laryngectomy, commonly known as a hemilaryngectomy, is a surgical procedure that involves the removal of a portion of the larynx, which is the voice box located in the throat. This procedure can be performed in different planes, specifically horizontal or vertical, depending on the location and extent of the cancer being treated. The latero-vertical hemilaryngectomy, represented by CPT® Code 31375, is specifically designed for cases where there is cancer affecting the anterior commissure, the vocal processes of the arytenoid cartilage, or glottic cancer. Prior to the surgery, a tracheostomy may be performed to facilitate anesthesia administration and ensure the patient's airway is secure during the procedure. The surgical approach involves making incisions in the neck to access the larynx, allowing for the removal of affected tissue while preserving as much healthy tissue as possible. This procedure is critical for patients with specific types of laryngeal cancer, as it aims to remove malignant tissue while maintaining vocal function to the greatest extent feasible.
