The VA rates trigeminal neuralgia under 38 CFR 4.124a using the criteria for the fifth cranial nerve. Diagnostic Code 8205 pays 10% for moderate incomplete paralysis, 30% for severe incomplete paralysis, and 50% for complete paralysis. Neuritis of the trigeminal nerve uses DC 8305 and neuralgia uses DC 8405, but both are evaluated against the same 8205 scale. The detail that decides most claims is a single sentence in 38 CFR 4.124: ordinary neuralgia caps out at 10%, but tic douloureux, the older clinical name for trigeminal neuralgia, "may be rated up to complete paralysis of the affected nerve." That sentence is what makes a 30% or 50% rating legally available for this condition when it would not be for other facial nerve pain.
Ratings for cranial nerves are assigned per side. If both sides of your face are involved, the VA rates each side and combines them, but without applying the bilateral factor that boosts paired-extremity ratings.
Trigeminal Neuralgia VA Rating Chart 2026
| Rating | Criteria under DC 8205 | 2026 monthly payment (veteran alone) |
|---|
| 50% | Complete paralysis of the fifth cranial nerve | $1,132.90 |
| 30% | Incomplete paralysis, severe | $552.47 |
| 10% | Incomplete paralysis, moderate | $180.42 |
| 0% | Diagnosis with no compensable sensory or motor findings | $0 |
Payments reflect the 2.8% COLA effective December 1, 2025. Veterans rated 30% or higher can add dependents to the award; the 10% rate is flat regardless of family size.
The rating table itself gives one instruction for choosing among the three levels: evaluation is "dependent upon relative degree of sensory manifestation or motor loss." The VA is not measuring how many attacks you have per week. It is measuring how much of the nerve's function is gone. That gap between how the condition feels and how it is scored is why so many veterans with debilitating facial pain land at 10%.
The Three Diagnostic Codes and Which One You Should Get
| Code | Condition | Ceiling | Source rule |
|---|
| 8205 | Paralysis of the fifth cranial nerve | 50% (complete) | 38 CFR 4.124a |
| 8305 | Neuritis of the fifth cranial nerve | 30% (severe incomplete), or 10% without organic change | 38 CFR 4.123 |
| 8405 | Neuralgia of the fifth cranial nerve | 10% (moderate), unless tic douloureux applies | 38 CFR 4.124 |
Most trigeminal neuralgia claims are coded 8405. Read plainly, 38 CFR 4.124 says neuralgia is rated on the paralysis scale "with a maximum equal to moderate incomplete paralysis," which for the trigeminal nerve is 10%. The very next sentence carves out the exception: tic douloureux, also called trifacial neuralgia, may be rated up to complete paralysis. Classic trigeminal neuralgia is tic douloureux. If a rating decision denies you anything above 10% by citing the general neuralgia cap, that decision has applied the rule and skipped the exception, and it is one of the more winnable errors to raise on a Higher-Level Review.
DC 8305 covers neuritis, which 38 CFR 4.123 describes as loss of reflexes, muscle atrophy, sensory disturbance, and constant pain that is at times excruciating. Neuritis can be rated up to severe incomplete paralysis, which is 30% here. Without those organic changes, the rating is held to the moderate level. Veterans with post-traumatic or post-surgical trigeminal injury who have documented numbness plus constant burning pain often fit 8305 better than 8405, and the code assignment can matter more than the exam findings.
How the VA Separates Moderate from Severe
There is no numerical formula. Rating specialists compare the whole picture against the words "moderate" and "severe," and Board decisions on this code tend to weigh a consistent set of facts.
Findings that support 10%:
- Intermittent stabbing pain in one or two trigeminal branches
- Pain reasonably controlled on carbamazepine, oxcarbazepine, or gabapentin
- Sensation intact or only mildly diminished on exam
- Normal jaw strength, normal corneal reflex
Findings that push toward 30%:
- Pain in all three divisions, or attacks triggered by chewing, shaving, brushing teeth, or wind on the face
- Objective sensory loss across the affected side documented on neurological exam
- Breakthrough pain despite maximum tolerated medication
- Avoidance of eating on the affected side, weight loss, dental neglect from touch avoidance
- Post-surgical numbness following microvascular decompression, rhizotomy, or gamma knife radiosurgery
Findings that support 50%:
- Anesthesia or profound sensory loss across the full trigeminal distribution
- Absent corneal reflex with keratitis risk
- Weakness or atrophy of the masseter and temporalis muscles, jaw deviating to the affected side
- Anesthesia dolorosa, meaning numbness and severe pain at the same time, a known complication after ablative procedures
Treatment history is evidence, not a disqualifier. A veteran whose pain is controlled by 1,200 mg of carbamazepine daily is not "not disabled." The VA rates the condition, and the medication side effects, drowsiness, cognitive slowing, low sodium, and required blood monitoring, belong in the record. If gamma knife or microvascular decompression left permanent facial numbness, that residual numbness is exactly the sensory manifestation DC 8205 asks about, and it does not go away when the pain does.
Getting Service Connected
Trigeminal neuralgia rarely shows up in a service treatment record with that name. Claims usually succeed by connecting it to a documented in-service event.
Direct service connection. Facial trauma, mandible or maxilla fracture, blast exposure, motor vehicle accidents, and combat injuries to the face can damage the trigeminal nerve. Look for anything in your records describing facial numbness, jaw pain, or "electric" facial pain, even if no diagnosis followed.
Dental trauma and in-service dental procedures. Third molar extractions, root canals, implants, and mandibular nerve blocks are recognized causes of trigeminal nerve injury. If military dental records document a difficult extraction followed by lasting numbness or pain, that is a direct-connection path. Dental treatment records are stored separately from medical service treatment records, so request them specifically.
Secondary to traumatic brain injury. TBI with skull base or facial involvement can produce trigeminal nerve dysfunction. If TBI is already service connected, trigeminal neuralgia can be claimed as secondary under 38 CFR 3.310, which requires a medical opinion tying the two together.
Secondary to multiple sclerosis. MS is a well-documented cause of trigeminal neuralgia through demyelination of the nerve root. Veterans with service-connected MS should claim trigeminal neuralgia as a separate secondary condition rather than assuming it is folded into the MS rating.
Section 1151 claims. If a VA dental or surgical procedure caused the nerve injury, compensation may be available under 38 U.S.C. 1151 even without service connection, provided there was VA fault or an unforeseeable event.
Secondary Claims Worth Filing
Chronic facial pain does not stay in the face. These secondary claims are commonly granted alongside a service-connected trigeminal neuralgia rating.
| Secondary condition | Typical code | What links it |
|---|
| Depressive disorder | DC 9434 | Chronic pain, social withdrawal, loss of eating and speaking function |
| Anxiety disorder | DC 9400 | Anticipatory fear of attacks, avoidance behavior |
| Insomnia | Rated with the mental disorder | Nocturnal attacks and pain-disrupted sleep |
| Headaches or migraines | DC 8100 | Trigeminal system overlap with headache pathways |
| Dental and jaw complications | Multiple | Touch avoidance leading to neglect, TMJ dysfunction |
| Weight loss or malnutrition | Varies | Inability to chew on the affected side |
Mental health secondaries are the highest-value add. A rating of 30% for the nerve plus 50% for a depressive disorder combines to 65%, which rounds to 70%. If your TBI is service connected and a depressive disorder appeared within three years of a moderate or severe TBI, or within twelve months of a mild TBI, 38 CFR 3.310(d) allows the VA to presume the connection without a separate nexus opinion.
Filing the Claim, Step by Step
- File an intent to file. Submit VA Form 21-0966 or start the claim online at VA.gov. This locks in your effective date for up to a year while you gather evidence.
- Collect the diagnosis. You need a documented diagnosis from a neurologist, neurosurgeon, or oral surgeon. Imaging that shows neurovascular compression of the trigeminal root, usually a high-resolution MRI sequence such as FIESTA or CISS, strengthens the file considerably.
- Document severity over time. Keep a pain log covering attack frequency, duration, triggers, and which divisions of the nerve are involved. Note foods you cannot eat and hygiene tasks you avoid. Record every medication and dose change.
- Get lay statements. A spouse or coworker describing you dropping mid-sentence from a facial attack tells the rater something a clinic note does not.
- Obtain a nexus opinion if the claim is secondary or based on remote trauma. The opinion should state that the condition is at least as likely as not related to the in-service event or the service-connected disability, and explain the medical reasoning.
- Submit VA Form 21-526EZ with all evidence attached. File the mental health secondary at the same time if it applies.
- Attend the C&P exam. The examiner will use the cranial nerves DBQ. Describe your worst days, not your average day, and say plainly which parts of your face are numb and whether touch triggers pain.
- Appeal within one year if the rating is low. Options are a Higher-Level Review (VA Form 20-0996) for a rating error such as the misapplied neuralgia cap, a Supplemental Claim (VA Form 20-0995) if you have new evidence, or a Board appeal (VA Form 10182).
Rule Changes on the Horizon
On November 12, 2024, the VA published a proposed rule updating the rating schedule for neurological conditions and convulsive disorders. The comment period closed on January 13, 2025. Among other changes, the proposal would relocate the schedule of ratings from 38 CFR 4.124a into 38 CFR 4.124 and would direct that cranial nerves with a compensable evaluation at the moderate level be rated at that moderate level when there is incomplete or complete sensory neuropathy. As of this writing the final rule has not taken effect, so the criteria described above are the ones being applied to claims. If the rule is finalized, existing ratings are typically protected from reduction based solely on new criteria, and veterans can request evaluation under whichever version is more favorable.
Frequently Asked Questions
What is the highest VA rating for trigeminal neuralgia?
50%, assigned under DC 8205 for complete paralysis of the fifth cranial nerve on one side. Because trigeminal neuralgia is tic douloureux, 38 CFR 4.124 permits a rating up to the complete paralysis level rather than capping it at the ordinary neuralgia maximum of moderate incomplete paralysis.
Can trigeminal neuralgia be rated on both sides of the face?
Yes. Cranial nerve ratings are for unilateral involvement. Bilateral trigeminal neuralgia is rated separately for each side and the two are combined, but the bilateral factor used for paired arms and legs does not apply to cranial nerves.
Does taking carbamazepine hurt my rating?
It should not. The rating depends on sensory manifestation and motor loss, not on whether you take medication. Document breakthrough pain, dose escalations, and side effects such as drowsiness, dizziness, low sodium, and required lab monitoring. If medication controls your pain fully and you have no sensory deficit, a 10% rating is the likely outcome.
Will surgery lower my VA rating?
Microvascular decompression or gamma knife radiosurgery may reduce pain, but both frequently leave permanent facial numbness. That numbness is a sensory manifestation the rating criteria specifically consider. Anesthesia dolorosa, numbness combined with persistent pain, is a recognized complication that can support the higher levels. Report all post-surgical residuals rather than only whether the pain returned.
How do I claim depression secondary to trigeminal neuralgia?
Get a mental health diagnosis, then a nexus opinion stating the depression is at least as likely as not caused or aggravated by the chronic facial pain. File it on the same VA Form 21-526EZ. If you have a service-connected TBI and the depression began within the timeframes in 38 CFR 3.310(d), the connection may be presumed without a separate opinion.
Can I get a TDIU rating for trigeminal neuralgia?
Yes, if the condition prevents substantially gainful employment. A 30% or 50% schedular rating alone does not meet the TDIU percentage threshold, so most veterans reach it by combining the nerve rating with secondary mental health and other service-connected conditions, or by requesting extraschedular consideration under 38 CFR 4.16(b) when attacks triggered by speaking or chewing make work impossible.
What if the VA rated me at 10% and cited the neuralgia maximum?
That is the most common rating error on this condition. The general rule in 38 CFR 4.124 caps neuralgia at moderate incomplete paralysis, but the same section states that tic douloureux may be rated up to complete paralysis. File a Higher-Level Review and identify the misapplication of law directly, citing your diagnosis of trigeminal neuralgia or tic douloureux.
