What 64647 covers

This service involves injecting a chemodenervating agent, commonly botulinum toxin, into six or more distinct trunk muscles to reduce unwanted muscle activity. Neurologists, physiatrists, and other qualified clinicians may perform it in an office or outpatient facility for conditions such as trunk spasticity or dystonia. Paraspinal and abdominal muscles are examples of trunk targets; the treated muscles should be identified in the record.

Select this code based on the number of distinct trunk muscles treated, not the number of needle passes or injection points. Documentation should support the indication and identify the muscles injected; report the toxin product separately when applicable. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and 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.

64647 billing questions

When should this code be selected instead of 64646?

Use 64647 when six or more trunk muscles are treated. Code 64646 is for one to five trunk muscles.

Do injection points determine the muscle count?

No. Select the code by the number of distinct muscles treated, not the number of needle passes or injection points. Document the muscles injected.

Can modifier 50 be used for injections on both sides of the trunk?

No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.

Is the botulinum toxin product included in this service?

The code represents the chemodenervation procedure. Report the toxin product separately under its applicable drug code when separately reportable.

How does the 0-day global period affect same-day care?

Same-day preoperative and postoperative care is included in the procedure's payment.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

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.
