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

What 31574 covers

An otolaryngologist or laryngologist passes a flexible laryngoscope to visualize the vocal folds and injects material to add bulk to one fold. This is commonly performed for glottic insufficiency, such as when vocal fold paralysis, paresis, or atrophy leaves an incomplete closure affecting voice or airway protection. The procedure may be performed in an office or facility, using an approach such as transoral or percutaneous injection.

Report this code for augmentation of one vocal fold under flexible endoscopic guidance, not for a diagnostic examination alone or an injection with a different therapeutic purpose. The record should identify the treated side, indication, injection approach, and augmentation performed. For bilateral treatment, CMS pays with modifier 50 at 150%. When related endoscopies are performed together, endoscopy family pricing applies. The 0-day global period includes same-day preoperative and postoperative care. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
