CPT® Code 31368

The procedure described by CPT® Code 31368 involves a subtotal supraglottic laryngectomy (SGL) combined with a radical neck dissection (RND). This surgical intervention is primarily indicated for the treatment of cancer that originates from specific areas of the larynx, including the epiglottis, aryepiglottic folds, and false vocal cords. The goal of the subtotal supraglottic laryngectomy is to excise the cancerous tissue while preserving essential laryngeal functions, which include airway protection, respiration, and the ability to produce sound (phonation). Prior to the laryngectomy, a tracheostomy is performed to ensure that the airway remains secure and separate from the surgical site. The procedure involves a series of meticulous steps, including the creation of a horizontal incision in the neck, the careful dissection of surrounding tissues, and the removal of the affected laryngeal structures. The radical neck dissection component entails the removal of lymph nodes and surrounding tissues to ensure comprehensive cancer treatment. This combination of procedures is critical for managing advanced laryngeal cancers and optimizing patient outcomes.
