CPT® Code 31561

The procedure described by CPT® Code 31561 is known as direct laryngoscopy with arytenoidectomy, which involves the surgical removal or vaporization of the arytenoid cartilage in the larynx. The arytenoids are crucial structures that play a significant role in voice production and airway management. Arytenoidectomy is typically performed to alleviate breathing difficulties, particularly in patients suffering from bilateral vocal cord paralysis, a condition where both vocal cords are unable to move properly, leading to airway obstruction. During this procedure, a direct laryngoscope is utilized, which is a specialized instrument that allows the physician to visualize the laryngeal structures directly through fiberoptic technology. There are two main types of direct laryngoscopes: rigid and flexible. The rigid angled scope is predominantly used in surgical settings and is inserted through the mouth while the patient is under general anesthesia. This allows for a thorough examination of the oral cavity, oropharynx, hypopharynx, larynx, and trachea. To perform the arytenoidectomy, the larynx is carefully exposed, often with the aid of a suspension device to ensure optimal visibility of the glottis. The procedure involves vaporizing the mucosa over the arytenoids and corniculate cartilage using a laser, which facilitates access to the arytenoid cartilage itself. The surgeon then vaporizes part or all of the arytenoid cartilage to improve the patient's airway. The use of an operating microscope or telescope during this procedure enhances visualization, allowing for more precise and meticulous vaporization of the tissues involved. It is important to note that CPT® Code 31560 should be used when the procedure is performed without the assistance of an operating microscope or telescope, while CPT® Code 31561 is specifically designated for cases where these advanced visualization tools are employed.
