The VA rates sciatica under diagnostic code 8520 for the sciatic nerve, with ratings running from 10% for mild incomplete paralysis up to 80% for complete paralysis. Most veterans with a service-connected sciatica claim land between 10% and 40%, depending on how much motor weakness, sensory loss, and pain document in the medical record. In 2026, a single 20% rating pays $356.66 a month, while a 40% rating pays $795.84 a month, with actual amounts depending on your combined rating and dependents.
Sciatica itself is a symptom, not a standalone diagnosis. It happens when the sciatic nerve, the longest nerve in the body, gets compressed or irritated, usually from a lower back condition like degenerative disc disease, spinal stenosis, or a herniated disc. Because of that, most VA sciatica claims are filed as secondary conditions tied to an existing service-connected back disability, though direct service connection is possible if the nerve damage traces to an in-service injury.
How the VA Rates Sciatica
The VA evaluates sciatic nerve damage under 38 CFR 4.124a, primarily using diagnostic code 8520 for paralysis of the sciatic nerve. Two related codes, 8620 (neuritis) and 8720 (neuralgia), cover inflammation and nerve pain without full paralysis and cap out lower than 8520.
| Diagnostic Code | Condition Type | Rating Range | Maximum |
|---|
| DC 8520 | Paralysis of the sciatic nerve | 10% to 80% | 80% |
| DC 8620 | Neuritis of the sciatic nerve | 10% to 60% | 60% |
| DC 8720 | Neuralgia of the sciatic nerve | 10% to 20% | 20% |
Because DC 8520 has the widest range and is used most often, it's the one that determines most sciatica ratings.
VA Rating Percentages for Sciatica (DC 8520)
| Rating | Severity Level | Typical Symptoms |
|---|
| 10% | Mild incomplete paralysis | Occasional tingling, mild pain, minimal functional limitation |
| 20% | Moderate incomplete paralysis | More frequent pain and numbness, noticeable but not disabling weakness |
| 40% | Moderately severe incomplete paralysis | Significant motor weakness, reduced reflexes, consistent functional limitation |
| 60% | Severe incomplete paralysis with marked muscular atrophy | Substantial muscle wasting, major weakness, near-constant pain |
| 80% | Complete paralysis | Foot drop, no active movement of muscles below the knee, weakened or lost knee flexion |
A rating that is "wholly sensory" (meaning the veteran only reports numbness or tingling with no measurable motor loss) is limited to the mild or, at most, the moderate level under VA regulations, even if the pain is severe.
What a Sciatica Rating Pays in 2026
VA disability compensation increased 2.8% for 2026 due to the annual cost-of-living adjustment, effective December 1, 2025. Here are the current monthly rates for a single veteran with no dependents:
| Combined Rating | Monthly Payment (Veteran Alone) |
|---|
| 10% | $180.42 |
| 20% | $356.66 |
| 30% | $552.47 |
| 40% | $795.84 |
| 50% | $1,132.90 |
| 60% | $1,435.02 |
Veterans rated 30% or higher receive additional compensation for a spouse, children, or dependent parents. Ratings at 10% and 20% do not increase for dependents. If sciatica is one of several service-connected conditions, the VA combines all your ratings using VA math (not simple addition) to reach your overall combined rating and payment tier.
Bilateral Sciatica: Both Legs Affected
If sciatica affects both legs, the VA can assign a separate rating for each leg and then apply the bilateral factor, an extra 10% added to the combined value of both leg ratings before they're folded into your overall combined rating. This accounts for the added disability of having both lower extremities affected rather than just one. Document symptoms in each leg separately during your C&P exam so the examiner can rate them individually.
How to Get Service Connection for Sciatica
Most sciatica claims are filed as secondary conditions. To win a secondary claim, you generally need three things.
- A current diagnosis of sciatica or sciatic nerve damage, documented by a physician, ideally supported by an EMG (electromyography) or nerve conduction study.
- An existing service-connected condition, most often a lumbar spine condition like degenerative disc disease, spinal stenosis, or a herniated disc, that is medically linked to causing or aggravating the sciatic nerve irritation.
- A medical nexus opinion connecting the two, stating that the sciatica is "at least as likely as not" caused or worsened by the service-connected back condition.
If your sciatica traces directly to an in-service back injury rather than a condition you're already rated for, you can instead file for direct service connection, which requires service treatment records showing the injury and a link between that injury and your current sciatic nerve symptoms.
What Happens at the C&P Exam
The Compensation and Pension exam for sciatica checks reflexes, muscle strength, sensation, and gait. The examiner is looking for objective findings, not just reported pain, to determine which severity tier applies. Bring records of any EMG results, physical therapy notes, or imaging showing nerve root compression. Describe specifically how the nerve pain affects walking, standing, sitting, and work tasks, since functional impact is part of what determines whether you land at mild, moderate, moderately severe, or severe.
Common Reasons Sciatica Claims Get Denied or Underrated
- No nexus opinion linking sciatica to a service-connected back condition
- Missing objective evidence like EMG/nerve conduction studies, so the rating gets capped at the "wholly sensory" mild or moderate tier
- Inconsistent symptom reporting between VA treatment records and the C&P exam
- Sciatica claimed as its own diagnosis without evidence of the underlying cause, which can lead the VA to deny the claim outright
If you believe your sciatica rating doesn't reflect your actual symptoms, you can file a supplemental claim with new evidence, request a higher-level review, or appeal to the Board of Veterans' Appeals.
Sciatica, TDIU, and Combined Ratings
Sciatica rarely shows up as a veteran's only service-connected condition. It's most commonly paired with a lumbar spine rating, and the two are evaluated separately, then combined using VA math rather than simple addition. For example, a veteran with a 40% back rating and a 20% sciatica rating in one leg does not receive a 60% combined rating. Instead, the VA applies the second percentage against what's left of the veteran's overall efficiency after the first rating, which typically produces a combined value somewhat lower than a straight sum.
If sciatica and related back or nerve conditions leave a veteran unable to maintain substantially gainful employment, Total Disability based on Individual Unemployability (TDIU) may be worth pursuing even if the combined schedular rating falls short of 100%. TDIU pays at the 100% rate and generally requires either one condition rated at 60% or more, or a combined rating of 70% with at least one condition rated at 40% or more. Veterans whose sciatica symptoms severely limit standing, walking, or sitting for extended periods, common requirements in most jobs, should discuss TDIU eligibility with a VSO or accredited claims agent.
Increasing a Sciatica Rating Over Time
Sciatica ratings aren't necessarily permanent. If symptoms worsen, whether from advancing degenerative disc disease, a new injury, or progressive nerve damage, veterans can file a claim for increase. Fresh EMG results, a new nexus statement, or updated C&P exam findings showing greater motor loss or muscle atrophy can move a rating from mild to moderate, or from moderate to moderately severe. On the other hand, VA can also propose to reduce a rating if follow-up exams show improvement, so keeping consistent medical documentation matters even after the initial award.
Filing Your Claim
- Get a current diagnosis from a VA or private physician, with supporting EMG or nerve conduction testing if possible.
- Gather nexus evidence connecting the sciatica to a service-connected condition or an in-service event.
- File through VA.gov or with help from a Veterans Service Organization (VSO), using VA Form 21-526EZ.
- Attend the C&P exam and clearly describe how symptoms affect daily function in both legs if applicable.
- Review your rating decision and file a supplemental claim or appeal if the evidence doesn't match the assigned percentage.
Frequently Asked Questions
What is the highest VA rating for sciatica?
The maximum rating under diagnostic code 8520 is 80%, reserved for complete paralysis of the sciatic nerve, meaning foot drop with no active movement of muscles below the knee.
Can sciatica be rated as its own disability, or does it need a secondary claim?
It can be either. Most veterans file sciatica as secondary to a service-connected back condition like degenerative disc disease, but direct service connection is possible if the nerve damage can be traced to an in-service injury.
How much does a 20% VA rating for sciatica pay in 2026?
A 20% combined rating pays $356.66 per month for a veteran with no dependents, based on 2026 VA compensation rates effective December 1, 2025.
Does sciatica pain alone qualify for a higher rating without weakness or numbness?
No. If the sciatica is purely sensory, meaning only pain or tingling without measurable motor loss, VA regulations cap the rating at mild, or at most moderate, regardless of how severe the pain feels.
Can I get separate VA ratings for sciatica in both legs?
Yes. The VA can rate each leg separately and then apply a bilateral factor, adding 10% to the combined value of both ratings, before folding the total into your overall combined disability rating.
What evidence helps the most for a sciatica VA claim?
EMG or nerve conduction study results, physician documentation of reduced reflexes or motor weakness, and a clear medical nexus opinion linking the sciatica to a service-connected condition all strengthen a claim significantly.
Can I qualify for TDIU because of sciatica?
Possibly. If sciatica combined with related conditions like a back disability leaves you unable to hold substantially gainful employment, you may qualify for Total Disability based on Individual Unemployability, which pays at the 100% rate even if your combined schedular rating is lower.
Will my sciatica rating stay the same forever?
Not necessarily. You can file a claim for increase if symptoms worsen, and the VA can also schedule a reexamination that could lead to a reduction if your condition improves. Keeping updated medical records protects your rating either way.
