What 64615 covers

This service covers medication injections into muscles on both sides of the head and neck, commonly using onabotulinumtoxinA for chronic migraine. A neurologist or headache specialist may inject muscles such as the frontalis, temporalis, occipital, cervical paraspinal, and trapezius muscles in an office or outpatient facility. The service represents the overall bilateral treatment, rather than a separate charge for each injection site.

Select the code for bilateral chemodenervation of the covered head and neck muscles, and document the indication, treated sites, laterality, and dose. Report the bilateral code once for the session; modifier 50 does not increase its payment. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction. Related postoperative visits during the 10-day global period are included. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted. The toxin may be reported separately under its applicable drug code when supplied by the practice.

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.

64615 billing questions

Should modifier 50 be appended?

No. The code is already priced as bilateral, and modifier 50 does not increase payment.

Is the service reported per injection site or muscle?

Report the bilateral service once for the session, not once for each injection or treated muscle. Document the sites and dose.

Can the botulinum toxin drug be billed separately?

The practice may report the applicable drug code separately when it supplies the toxin. Keep documentation of the product and dose administered.

How does the 10-day global period affect follow-up visits?

Related postoperative visits during the 10 days after the procedure are included in the service.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full; other procedures in that session are subject to the standard 50% multiple-procedure reduction.

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.
