CPT® Code 31513

The procedure described by CPT® Code 31513 refers to an indirect laryngoscopy with vocal cord injection. This medical intervention is primarily aimed at addressing issues related to vocal fold atrophy or paralysis, conditions that can lead to a lack of bulk or mobility in the vocal cords. During the procedure, the patient is typically seated comfortably and instructed to extend their tongue. The physician utilizes a small round mirror positioned at the back of the throat, along with a head mirror to illuminate the area, allowing for a clear view of the vocal cords, tongue, and upper throat. In some cases, a rigid endoscope may be employed for enhanced visualization. The examination may involve the patient producing a high-pitched sound to facilitate better observation of the vocal cords. Following the assessment, a curved needle is carefully inserted through the mouth to deliver an injectable substance directly into the vocal fold, aimed at restoring its volume and function. The physician monitors the vocal cord's position during the injection, ensuring that it moves appropriately to make contact with the opposite vocal cord, which is essential for effective speech. The procedure may require additional injections to achieve the desired outcome, with the patient's vocal function being evaluated after each injection to assess the effectiveness of the treatment.
