CPT® Code 31560

The procedure described by CPT® Code 31560 is known as direct laryngoscopy with arytenoidectomy. This surgical intervention involves the excision or laser vaporization of the arytenoid cartilage, which is a critical component of the larynx, responsible for voice production and airway management. Arytenoidectomy is primarily indicated for patients suffering from bilateral vocal cord paralysis, a condition that can severely compromise the airway and hinder normal breathing. The use of a direct laryngoscope, which can be either a rigid angled scope or a flexible scope, allows the physician to visualize the laryngeal structures directly. The rigid scope is typically preferred for surgical procedures and is inserted through the mouth while the patient is under general anesthesia. During the procedure, the physician examines the oral cavity, oropharynx, hypopharynx, larynx, and trachea to ensure comprehensive assessment and treatment. To facilitate the surgery, a suspension device is utilized to maintain adequate exposure of the glottis, allowing for precise intervention. The mucosal layer covering the arytenoids and corniculate cartilage is vaporized using a laser, which helps to expose the arytenoids for the subsequent excision. The procedure may also involve the use of an operating microscope or telescope to enhance visualization and ensure meticulous vaporization of the tissues. It is important to note that CPT® Code 31560 is specifically used when the procedure is performed without the assistance of an operating microscope or telescope, while CPT® Code 31561 is designated for cases where such instruments are employed.
