ICD Code G50.0

ICD code G50.0 is trigeminal neuralgia, a chronic pain condition affecting the trigeminal nerve in the face, causing sudden, severe facial pain.

1. Sudden, severe, brief, stabbing or electric shock-like facial pain

2. Pain localized to one or more divisions of the trigeminal nerve (ophthalmic, maxillary, mandibular)

3. Pain episodes lasting from a fraction of a second to two minutes

4. Pain triggered by innocuous stimuli such as touching the face, chewing, speaking, or brushing teeth

5. Absence of neurological deficits on examination

6. No evidence of an underlying structural lesion causing the symptoms (such as tumor or multiple sclerosis)

7. Recurrent paroxysms of facial pain with pain-free intervals

Relevant CPT codes that may be used to treat ICD code G50.0 include:

- 64400: Injection, anesthetic agent; trigeminal nerve, any division or branch

- 64605: Destruction by neurolytic agent; trigeminal nerve, second and third division branches at foramen ovale

- 64610: Destruction by neurolytic agent; trigeminal nerve, third division branch at foramen ovale

- 63650: Percutaneous implantation of neurostimulator electrode array; spinal cord

- 61885: Insertion or replacement of cranial neurostimulator pulse generator or receiver, direct or inductive coupling; with connection to a single electrode array

- 61580: Craniectomy with microvascular decompression of cranial nerve
