About 31513: Indirect laryngoscopy with vocal-fold injection
Reports therapeutic injection into a vocal fold under indirect laryngoscopic visualization, commonly to improve glottic closure in vocal-fold paralysis or atrophy.
An otolaryngologist uses indirect laryngoscopic visualization while injecting material into a vocal fold to improve closure and voice function. Common clinical reasons include vocal-fold paralysis or atrophy causing glottic insufficiency. The service may be performed in an office or facility; the record should identify the indication, injection site and approach, and the material used when known.
Select this code when the therapeutic injection is performed with an indirect approach, rather than direct laryngoscopy. Document the treatment and visualization performed; diagnostic visualization alone does not support the injection service. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is inappropriate for this code. An assistant at surgery is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

Document the clinical reason for treatment, the vocal-fold site, the injection performed, and the indirect laryngoscopic visualization and approach.
Can a related endoscopy be separately reported at the same session?
When related endoscopies are performed together, CMS endoscopy family pricing applies. Report the services performed, with documentation supporting each service.
Is same-day preoperative or postoperative care separately included?
The 0-day global period includes same-day preoperative and postoperative care in the procedure.
What applies if an assistant or another surgeon participates?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
