What 31573 covers

An otolaryngologist or laryngologist passes a flexible scope to visualize the larynx and deliver one or more therapeutic injections. A common use is botulinum toxin injection for spasmodic dysphonia; medication may also be injected for another therapeutic purpose. The flexible approach distinguishes this service from injection performed during direct laryngoscopy. It is commonly performed in an office or procedural setting, with the record identifying the target and therapeutic agent.

Report the service when the flexible laryngoscopy and therapeutic injection are performed, not for diagnostic visualization alone or injection intended to augment vocal-fold volume. Document the approach, injection site, purpose, and medication. This minor 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. For a bilateral procedure, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

31573 billing questions

How does 31573 differ from 31574?

31573 is for therapeutic injection, such as botulinum toxin. Use 31574 when the injection is intended to augment vocal-fold volume.

How does 31573 differ from 31570 or 31571?

31573 uses a flexible laryngoscope. Codes 31570 and 31571 describe therapeutic vocal-cord injection performed through direct laryngoscopy.

Can diagnostic laryngoscopy be reported separately?

The flexible visualization needed to perform the therapeutic injection is part of 31573. A separate diagnostic scope service should not be reported for that same work.

How is a bilateral injection reported?

For a bilateral procedure, report modifier 50; CMS pays 150% under the rule for this code.

What documentation supports 31573?

Document the flexible approach, laryngeal injection site, therapeutic purpose, and medication used. For assistant-at-surgery payment, the record must establish medical necessity.

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.
