A burning, shooting pain that radiates from your lower back through your buttock and down one or both legs — that’s the hallmark of sciatica, and it’s a condition that plagues a significant number of veterans. Whether it developed from carrying heavy rucksacks, a training injury, or prolonged time in cramped military vehicles, sciatica can be debilitating long after service ends.
If your sciatica is connected to your military service, you may be entitled to VA disability compensation. This guide explains exactly how the VA evaluates sciatica, what rating you might receive, and what steps to take to file a successful claim.

What Is Sciatica?
Sciatica is not a diagnosis in itself — it’s a symptom of an underlying problem affecting the sciatic nerve, the largest nerve in the human body. The sciatic nerve originates in the lower back, runs through the hips and buttocks, and branches down each leg. When something compresses or irritates this nerve — a herniated disc, bone spur, or narrowed spinal canal — the result is the sharp, radiating pain that most people recognize as sciatica.
The VA classifies sciatica under the broader category of peripheral nerve conditions, using the medical term lumbar radiculopathy in many rating decisions. The condition can range from mild tingling and occasional discomfort to near-complete paralysis of the affected leg, which is why the VA’s rating system covers such a wide range of percentages.
Common Causes of Sciatica in Veterans
Military service puts extraordinary stress on the spine. Several common service-related factors can trigger or accelerate sciatic nerve damage:
- Heavy load-bearing: Carrying rucksacks, weapons systems, and gear over extended distances compresses the lumbar spine and can lead to disc herniation.
- Repetitive physical activity: Jumping, prolonged marching, and physical training create cumulative stress on the intervertebral discs.
- Prolonged sitting in vehicles: Extended time in cramped military vehicles — particularly Humvees, aircraft, and armored personnel carriers — can compress the sciatic nerve.
- Combat injuries: Blast injuries, falls, and direct trauma to the lower back or pelvis can damage the sciatic nerve directly.
- Spinal stenosis and disc disease: These conditions, which often develop due to military service, are among the most common underlying causes of sciatica in veterans.
Even seemingly minor incidents during service can have long-term effects. Veterans who were exposed to Agent Orange may also have elevated risk for nerve damage that can contribute to sciatic symptoms.
How the VA Rates Sciatica
The VA evaluates sciatica based on the severity of neurological impairment — specifically, the degree to which the sciatic nerve has been damaged. The rating system runs from mild neuralgia (10%) all the way to complete paralysis of the sciatic nerve (80%).
The VA uses 38 CFR § 4.124a, Schedule of Ratings – Peripheral Nerves, to evaluate conditions affecting the sciatic nerve. Three separate diagnostic codes apply, depending on the nature of the nerve damage.
Diagnostic Codes for Sciatica
| Diagnostic Code | Condition | Rating Range | What It Covers |
|---|---|---|---|
| 8520 | Paralysis of the Sciatic Nerve | 10% – 80% | Ranges from mild incomplete paralysis to complete paralysis with loss of function. The 80% rating is reserved for complete paralysis with foot drop and significant muscle atrophy. |
| 8620 | Neuritis of the Sciatic Nerve | 10% – 60% | Covers inflammation of the sciatic nerve, rated based on symptom severity from mild neuritis to severe, with symptoms like constant pain, weakness, and sensory loss. |
| 8720 | Neuralgia of the Sciatic Nerve | 10% – 20% | The least severe classification. Covers pain along the nerve’s path without significant motor impairment. Rated mild (10%) or moderate (20%). |
The VA will apply whichever diagnostic code best fits your documented symptoms and medical records. Ratings are also assigned separately for the left and right leg if both are affected.

Establishing Service Connection
Before the VA assigns a rating, you must prove that your sciatica is connected to your military service. There are several pathways to establish service connection:
Direct service connection requires three elements: a current diagnosis of sciatica or lumbar radiculopathy, an in-service event or injury that could have caused the condition, and a medical nexus — a professional opinion linking the two. Your service medical records, post-service treatment records, and a nexus letter from a qualified healthcare provider are all critical pieces of evidence.
Secondary service connection allows you to claim sciatica as a result of another service-connected condition. For example, if you have a service-connected herniated disc or degenerative disc disease, and those conditions are compressing your sciatic nerve, you can claim sciatica as a secondary condition. Lower back conditions are among the most common causes of secondary sciatica claims.
Aggravation applies if you had a pre-existing sciatic condition before service that was made permanently worse — beyond normal progression — by military duties.
Secondary Conditions to Sciatica
Sciatica itself can also give rise to secondary conditions that may be separately ratable. These include:
- Muscle atrophy: When the sciatic nerve is chronically compressed, the muscles it serves can begin to waste away. This is considered in the rating for paralysis under DC 8520.
- Depression and anxiety: Chronic, unrelenting nerve pain takes a serious toll on mental health. Veterans who develop depression or anxiety as a result of service-connected sciatica may be able to claim these conditions secondarily.
- Hip and knee problems: An abnormal gait caused by sciatic pain can place uneven stress on other joints, potentially leading to secondary joint conditions.
- Sleep disorders: Nerve pain that disrupts sleep may contribute to secondary service connection for sleep apnea or other sleep conditions in some cases.
Filing secondary claims alongside your sciatica claim can significantly increase your combined VA disability rating.
Bilateral Sciatica and the Bilateral Factor
When sciatica affects both legs — a condition called bilateral sciatica — the VA evaluates each leg separately under the appropriate diagnostic code, then applies the bilateral factor to the combined rating. The bilateral factor adds 10% to the combined value of the two ratings before rounding to the nearest 10%.
This is an important distinction. Veterans with bilateral sciatica should make sure both legs are fully documented in their claim, with separate evidence addressing the severity of each side’s impairment. Failing to claim both legs separately can result in an under-rating.
The VA also prohibits “pyramiding” — rating the same symptoms under more than one diagnostic code. If your sciatica arises from a herniated disc that is already rated, the VA cannot rate the same nerve pain twice. However, if the sciatic symptoms are distinct and separately documented, they can be rated on their own.

Filing Your VA Claim
Filing a well-organized claim gives you the best chance of receiving an accurate rating. Here are the key steps:
- Submit an Intent to File: This preserves your effective date (the date from which back pay is calculated) while you gather your evidence. You can submit an Intent to File online at VA.gov or by calling 1-800-827-1000.
- Gather medical evidence: Collect all records related to your sciatica, including imaging (MRI, X-ray), nerve conduction studies, and treatment notes. Include any records from your service that document back or leg pain.
- Obtain a nexus letter: A qualified physician or nurse practitioner should write a letter stating that it is “at least as likely as not” that your sciatica is connected to your military service.
- Complete VA Form 21-526EZ: This is the standard application for disability compensation. Be thorough and specific about your symptoms.
- Prepare for your C&P exam: The Compensation and Pension exam is a critical evaluation. Be honest and detailed about your worst days, not just your average ones. Describe how pain affects your ability to stand, walk, sit, and work.
Veterans Service Organizations (VSOs) such as the DAV, VFW, and American Legion provide free claims assistance and can help you build a stronger file.
What Compensation Can You Expect?
Your monthly compensation depends on your combined disability rating and your dependents. In 2026, a veteran with a 10% disability rating receives approximately $175 per month with no dependents. At 50%, that figure rises to roughly $1,075 per month, and at 80%, it exceeds $1,900 per month for a veteran with no dependents.
If your sciatica, combined with other service-connected conditions, brings your total rating to 50% or higher, you may also qualify for additional benefits including free VA healthcare, commissary and exchange access, and property tax exemptions in many states.

Frequently Asked Questions
Most veterans with sciatica receive ratings between 10% and 40%, depending on the severity of nerve impairment. A 10% rating for mild neuralgia is the most common entry-level rating. Veterans with documented incomplete paralysis, significant weakness, or sensory loss may receive 20%–40%, while complete or near-complete paralysis can result in ratings up to 80%.
Yes. Sciatica (lumbar radiculopathy) is one of the most common secondary conditions linked to service-connected lower back conditions such as herniated discs, degenerative disc disease, and spinal stenosis. If your service-connected back condition is compressing the sciatic nerve, you can file for secondary service connection for sciatica.
If your service-connected sciatica, alone or in combination with other disabilities, prevents you from holding substantially gainful employment, you may qualify for TDIU — which pays at the 100% rate regardless of your combined schedular rating. Documentation from your treating physician about your functional work limitations is essential for a TDIU claim.
Yes. If sciatica affects both legs, the VA will rate each leg separately and then apply the bilateral factor, which adds a small additional percentage to the combined rating. Make sure your claim documents symptoms in both legs with supporting medical evidence.
The most useful records include MRI or CT imaging of the lumbar spine, nerve conduction studies, service medical records documenting back or leg pain, treatment notes from a neurologist or orthopedic provider, and a nexus letter from a qualified healthcare professional linking your condition to your service.
