CPT® Code 31382

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 is indicated primarily for patients with laryngeal cancer, particularly when the cancer is localized to one side of the larynx. The term "hemilaryngectomy" refers to the fact that only a part of the larynx is excised, as opposed to a total laryngectomy, which involves the complete removal of the larynx. The procedure can be performed in different planes, specifically horizontal or vertical, depending on the location and extent of the cancer. In the case of an antero-latero-vertical hemilaryngectomy, which is represented by CPT® Code 31382, the surgical approach is more extensive. This procedure not only involves the removal of tissue from one side of the larynx but also includes the excision of the anterior commissure, the entire vocal cord on the contralateral side, and the underlying cartilage. 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 complexity of this surgery necessitates careful planning and execution to preserve as much function as possible while effectively removing cancerous tissues.
