The short answer
CPT 64615 is the procedure code for chemodenervation of muscles innervated by the facial, trigeminal, cervical spinal and accessory nerves, bilateral: the injection procedure for chronic migraine, such as Botox. Because the code already describes both sides, it is reported once per session without modifier 50. The drug is billed separately, commonly under J0585 for onabotulinumtoxinA. The code alone does not establish coverage; confirm the diagnosis, documentation and the patient’s payer policy.
Match the procedure to the documented service
CMS botulinum toxin articles distinguish procedure reporting from the drug supply. Do not choose a procedure solely because the appointment is called a Botox visit. The clinician’s documented indication, work performed and anatomy must support the code. Use a current licensed CPT reference for its complete instructions.
Build the medical-necessity record before billing
Chronic migraine coverage policies can require documented headache frequency, duration, prior therapies and response. The BOTOX label and a payer’s coverage criteria serve different purposes. Do not turn a label indication or one contractor’s criteria into a promise that every insurer will pay.
Your practical checklist
- Identify payer, plan, benefit and applicable policy version.
- Collect the clinician’s documented headache history and prior treatment outcomes.
- Verify authorization requirements and approved service details.
- Reconcile procedure, drug quantity and treatment record before claim submission.
A worked example
An authorization mentions chronic migraine, but the claim team has only a scheduling note saying “Botox follow-up.” The missing clinical record is the problem to resolve. Request the signed assessment and procedure documentation instead of adding a diagnosis simply to satisfy a claim edit.

Mistakes to avoid
- Using a cosmetic wrinkle appointment as support for a therapeutic claim.
- Copying a numeric frequency threshold from an outdated article.
- Promising reimbursement because an authorization number exists.
