Laryngology procedure
About 31574: Flexible laryngoscopy with vocal fold augmentation
A laryngologist uses flexible endoscopic guidance to inject augmentation material into one vocal fold, commonly to improve glottic closure and voice.
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.

31574 billing questions
When is this code appropriate instead of 31573?
Use this code for injection intended to augment a vocal fold, typically to improve closure. Code 31573 describes flexible laryngoscopy with a therapeutic injection, such as chemodenervation, rather than augmentation.
How should bilateral vocal fold augmentation be reported?
Report the bilateral procedure with modifier 50. CMS pays the bilateral procedure at 150%.
Can a diagnostic laryngoscopy be billed separately during the injection?
The flexible scope is used to guide the augmentation procedure. Do not separately report a diagnostic scope for the same examination work.
What documentation supports the service?
Document the indication for augmentation, the vocal fold treated, the flexible endoscopic guidance, and the injection approach and service performed.
How does the global period affect same-day care?
This procedure has a 0-day global period. Same-day preoperative and postoperative care is included.
