CPT code 31515 represents direct laryngoscopy with aspiration of material from the larynx, sometimes including tracheoscopy to inspect the trachea. Nationally, this procedure is a focused airway diagnostic and therapeutic maneuver used in acute and perioperative care to clear secretions, blood, or aspirated material and to evaluate laryngeal and tracheal pathology. It matters because timely visualization and removal of obstructing material can affect airway patency, perioperative safety, and emergency airway management outcomes.
