VA Disability Rating for Trigeminal Nerve Paralysis (DC 8205)
Diagnostic Code 8205 · 38 CFR §4.124a
What Is It?
The trigeminal nerve (5th cranial nerve) is the largest cranial nerve and provides sensation to the face and controls the muscles used for chewing. Paralysis or damage to this nerve causes numbness in the face, difficulty chewing, jaw weakness, and potentially severe facial pain known as trigeminal neuralgia. Veterans may damage this nerve from facial or skull fractures in combat, blast injuries, dental procedures during service, brain tumors, or as a complication of brain surgery. The resulting facial numbness can be dangerous because you may not feel injuries, burns, or dental problems on the affected side.
Rating Criteria
| Rating | Criteria |
|---|---|
| 50% | Complete paralysis of the trigeminal nerve with total loss of facial sensation on the affected side, complete inability to chew on that side, and severe pain if neuralgia is present. |
| 30% | Severe incomplete paralysis with significant sensory loss across multiple facial divisions, marked chewing difficulty, and moderate to severe pain. |
| 10% | Moderate incomplete paralysis with partial facial numbness, mild chewing difficulty, or intermittent pain episodes. |
Evidence Needed
- Neurological examination documenting sensory loss in specific trigeminal divisions
- EMG of the muscles of mastication showing denervation
- Brain or facial MRI showing the site of nerve damage
- Service records documenting the facial injury, surgery, or condition causing the nerve damage
- Treatment records for trigeminal neuralgia if pain is present
- Dental records if chewing difficulty has caused dental problems
C&P Exam Tips
- Have the examiner test all three divisions of the trigeminal nerve separately (forehead, cheek, jaw)
- Demonstrate jaw weakness and difficulty chewing if present
- Describe the pattern and severity of any facial pain
- Report any injuries to your face you did not feel because of the numbness
- Explain how facial numbness or pain affects eating, dental care, and daily activities
- If you have trigeminal neuralgia pain, describe the triggers and intensity
How to File
File under DC 8205 for paralysis of the 5th cranial nerve. Include neurological examination findings mapping the sensory loss, EMG results if chewing muscles are affected, and imaging showing the nerve damage. If the damage resulted from a service-connected facial injury or surgery, document that connection.
Common Mistakes
Not having all three divisions tested separately Not claiming trigeminal neuralgia pain Not noting the bilateral versus unilateral distinction
Frequently Asked Questions
What is trigeminal neuralgia?
Trigeminal neuralgia is a condition causing sudden, severe, electric shock-like facial pain triggered by everyday activities like eating, talking, or touching the face. It is one of the most painful conditions known and can develop from damage to the trigeminal nerve. If you have this condition from a service-connected injury, it is rated as part of your trigeminal nerve disability.
Can trigeminal nerve damage affect both sides?
Yes, although unilateral damage is more common. Bilateral trigeminal nerve paralysis is particularly disabling because it affects sensation across the entire face and makes chewing extremely difficult. Bilateral involvement warrants higher ratings.
