CPT® Code 31577

The procedure described by CPT® Code 31577 refers to a flexible laryngoscopy that includes the removal of foreign body(ies) from the larynx. This procedure is typically performed when a patient presents with a suspected obstruction or irritation in the airway due to foreign objects. A flexible laryngoscope, which is a thin, flexible tube equipped with a light and camera, is utilized to visualize the larynx and surrounding structures. The procedure begins with the application of a topical anesthetic to ensure patient comfort and minimize gag reflex during the examination. The laryngoscope is then introduced through the nasal passage, allowing for a thorough examination of the pharynx, vocal cords, and hypopharynx. If a foreign body is identified, it is carefully grasped using specialized forceps and removed through the laryngoscope. This procedure is essential for addressing airway obstructions and preventing further complications associated with foreign body presence in the laryngeal area.
