What 64616 covers

This service involves injecting a medication such as botulinum toxin into neck muscles to reduce involuntary muscle activity. Neurologists, physiatrists, and other clinicians who treat movement disorders commonly perform it in an office or facility setting. Cervical dystonia, with involuntary neck contractions or abnormal head posture, is a typical indication. The code is for neck muscles and excludes laryngeal muscle treatment.

Select the code based on the treated anatomy and clinical service, not simply the injection location or number of injection sites. Document the indication, muscles treated, medication, and treatment details. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; 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.

64616 billing questions

When should this code be chosen instead of 64615?

Use 64616 for treatment directed at neck muscles, commonly for cervical dystonia. Code 64615 is for chemodenervation directed at muscles for chronic migraine treatment.

Can this code be used for injections into laryngeal muscles?

No. Laryngeal muscle treatment is reported with 64617, which identifies laryngeal chemodenervation with EMG guidance.

How is bilateral treatment reported?

Report modifier 50 for bilateral treatment. CMS pays the bilateral procedure at 150%.

Are follow-up visits included?

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

What documentation supports reporting this code?

Document the clinical indication, the neck muscles treated, the medication administered, and the treatment performed. The record should distinguish neck treatment from laryngeal, facial, or extremity muscle treatment.

How does CMS handle this code when other procedures are performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid 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.
