What 64567 covers
This service uses fine percutaneous electrodes at external-ear sites to deliver electrical stimulation to cranial nerve branches. A typical use is treatment of functional abdominal pain associated with irritable bowel syndrome, including in adolescents. The treating clinician places the electrodes and activates the stimulation device; the service is distinct from surgically implanting a permanent cranial nerve stimulator. It may be furnished in an outpatient clinic by a clinician managing the patient’s pain or gastrointestinal condition.
Report the code for the cranial nerve field stimulation service, not separately for each electrode. Documentation should identify the clinical indication, the treatment performed, electrode placement, and device activation. Select a different code when the service instead involves posterior tibial nerve stimulation or surgical implantation of a cranial nerve electrode and pulse generator.

64567 billing questions
Does this code represent each electrode placed?
No. It represents the cranial nerve field stimulation service, rather than a separate service for each auricular electrode.
What should the record document?
Document the indication, the stimulation treatment performed, electrode placement, and device activation.
How is this different from 64566?
64567 describes cranial nerve field stimulation, commonly using auricular sites. 64566 is for percutaneous stimulation of the posterior tibial nerve.
Is this the code for permanent vagus nerve stimulator implantation?
No. 64567 describes percutaneous electrical nerve field stimulation. Open implantation of a cranial nerve electrode array and pulse generator is represented by 64568.
Is this code reported for functional abdominal pain treatment?
It may describe cranial nerve field stimulation used for functional abdominal pain associated with irritable bowel syndrome. The record should support the patient’s indication and the treatment performed.
