Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 31513 covers

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.
