What 31570 covers

An otolaryngologist performs direct laryngoscopy and injects a therapeutic agent into one or both vocal folds. A typical use is botulinum toxin treatment for spasmodic dysphonia. The code describes the direct approach without an operating microscope or telescope, unlike 31571, and is commonly furnished in an operative setting.

Select 31570 when documentation supports direct laryngeal access and therapeutic injection, rather than flexible-scope injection, lesion treatment, or a diagnostic-only examination. Document the indication, target vocal fold or folds, injected agent, approach, and therapeutic purpose. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, endoscopy-family pricing applies. The descriptor covers vocal cord(s), so a bilateral adjustment is inappropriate. Medicare does not pay for an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

31570 billing questions

How does 31570 differ from 31571?

Both describe direct laryngoscopy with therapeutic vocal-fold injection. Use 31571 when the procedure includes an operating microscope or telescope.

When is 31573 or 31574 a better fit?

Those codes describe flexible laryngoscopy with injection. 31573 covers therapeutic injection, including specified unilateral treatment; 31574 is for injection for vocal-fold augmentation.

Can 31570 be reported for injections into both vocal folds?

The descriptor covers injection into vocal cord(s). Do not apply a bilateral adjustment or modifier 50.

Can diagnostic laryngoscopy be billed separately with 31570?

The laryngoscopy used to perform the injection is part of the service. A separate diagnostic laryngoscopy should not represent that same procedural work.

What documentation supports 31570?

Document the therapeutic indication, direct approach, vocal fold target or targets, injected agent, and purpose of the injection.

How does payment work when related endoscopies are performed together?

CMS endoscopy-family pricing applies when related endoscopies are performed together. The service has a 0-day global period, and assistant-at-surgery, co-surgeon, and team-surgery billing are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
