What 64611 covers

This service uses injected medication to reduce saliva production by treating the parotid and submandibular glands on both sides. It is commonly performed for persistent drooling, including in patients with neurologic conditions such as cerebral palsy, Parkinson disease, or stroke. Neurologists, otolaryngologists, and other clinicians who manage sialorrhea may provide the injections in office or facility settings.

Report the code for the bilateral gland treatment, not for injections into facial or other muscles. Document the indication, glands treated, laterality, medication and dose, and the procedure performed. The code is priced as bilateral; modifier 50 does not increase payment. Related postoperative visits are included in its 10-day global period. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment requires documented medical necessity; 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.

64611 billing questions

When should 64611 be chosen over 64612?

Use 64611 for bilateral parotid and submandibular gland chemodenervation to reduce saliva. Code 64612 describes chemodenervation of facial muscles, not salivary glands.

Is modifier 50 needed for the bilateral treatment?

The code is already priced as bilateral, and modifier 50 does not increase payment. Document that the bilateral gland treatment was performed.

How many units should be reported for treatment of both sides?

Report the bilateral service as one code rather than a separate unit for each gland or side. The code's bilateral pricing does not support an increased payment from modifier 50.

Is the medication included in the procedure code?

The code reports the gland chemodenervation procedure. Any separately reportable drug supply depends on how the medication was furnished and applicable drug-billing requirements.

What documentation supports 64611?

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.
