Consider This Clinical Chemodenervation Example

Question: Encounter notes indicate a patient reports complaining of chronic migraine headaches. The patient states that they have had 18 headache days per month lasting longer than four hours each for four months. Average pain rated 6/10. Botox injections have been helpful in the past, with a 60 percent reduction in headache intensity. The patient currently reports photophobia and sensitivity to sounds. The provider administers botulinum toxin was administered: 155 units given, 45 wasted. How should I report this encounter?

Answer: For this encounter, you’d report:

  • 64615 (Chemodenervation of muscle(s); muscle(s) innervated by facial, trigeminal, cervical spinal and accessory nerves, bilateral (eg, for chronic migraine)) for the chemodenervation.
  • G43.709 (Chronic migraine without aura, not intractable, without status migrainosus) appended to 64616 to represent the patient’s migraine.
  • J0585 (Injection, onabotulinumtoxinA, 1 unit) x 155 units to represent the amount of Botox the provider used during the chemodenervation.
  • J0585 x 45 units to represent the amount of Botox unused during the chemodenervation.

Modifier JW (Drug amount discarded/not administered to any patient) appended to J0585 x45 to show that this is the amount of Botox wastage during the chemodenervation.
