What 64617 covers

This service delivers a chemodenervating agent through the skin into a targeted laryngeal muscle. Otolaryngologists and laryngologists commonly use it for adductor laryngeal dystonia, also called spasmodic dysphonia; a typical target is the thyroarytenoid muscle. Treatment may be performed in an office or facility. EMG guidance used to localize the muscle is included in the procedure when performed.

Report the code for unilateral treatment and document the indication, targeted muscle, injection, and laterality. For bilateral treatment, modifier 50 applies; CMS pays the bilateral procedure at 150%. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

64617 billing questions

When should 64617 be used instead of 64616?

Use 64617 for percutaneous chemodenervation of laryngeal muscle or muscles. Code 64616 addresses chemodenervation of neck muscles, not the laryngeal target.

Can both sides be treated with 64617?

Yes. Report bilateral treatment with modifier 50; CMS pays it at 150%.

Can EMG guidance be billed separately?

EMG guidance is included when performed as part of 64617. Document the guidance and the muscle targeted.

Is the injected drug included in 64617?

The procedure code describes the chemodenervation service, not the drug supply. Report the applicable drug code separately when the drug is supplied and separately reportable.

Are postoperative visits separately reported during the global period?

Related postoperative visits during the 10-day global period are included in 64617.

How does the multiple-procedure rule affect payment?

For multiple procedures in the same session, CMS pays the highest-valued procedure in full and the others at 50%.

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.
