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.
