What is sciatica and how does it affect veterans?
Sciatica is pain that radiates along the path of the sciatic nerve — the longest and largest nerve in the body, running from the lower back through each hip and buttock and down the back of each leg to the foot. It occurs when the sciatic nerve is compressed or irritated, most commonly by a herniated disc, bone spur, or spinal stenosis in the lumbar spine.
Veterans are at high risk for sciatica due to the physical demands of military service. Years of carrying heavy rucksacks and body armor, high-impact training, parachute operations, prolonged vehicle operation, and combat-related injuries all place enormous stress on the lumbar spine. Over time, this leads to the disc herniations and degenerative changes that compress the sciatic nerve.
Sciatica produces sharp, shooting, or burning pain that travels from the lower back down through the buttock and into the leg — sometimes all the way to the foot. Many veterans also experience numbness, tingling, and muscle weakness in the affected leg. The pain can range from a mild ache to an excruciating, debilitating sensation that makes walking, sitting, standing, and sleeping extremely difficult.
For many veterans, sciatica is not just pain — it fundamentally changes what you can do. You may be unable to sit at a desk, drive for extended periods, exercise, or perform physical labor. The condition often worsens over time, particularly without treatment, and can lead to permanent nerve damage.
The VA rates sciatica under DC 8520 for paralysis of the sciatic nerve. This rating is assigned separately from any rating for the underlying back condition, which many veterans don’t realize.
IVDS exception: If your condition is intervertebral disc syndrome (DC 5243), VA can rate it by range of motion (General Rating Formula, plus separate nerve ratings) or by incapacitating episodes (no separate nerve ratings), and uses whichever gives you the higher combined rating.
VA diagnostic code for sciatica
Sciatica is rated under Diagnostic Code (DC) 8520 per 38 CFR § 4.124a, Schedule of Ratings — Diseases of the Peripheral Nerves, covering paralysis of the sciatic nerve.
This is the same code used for lumbar radiculopathy affecting the sciatic nerve. The VA evaluates the degree of nerve paralysis regardless of whether the condition is called “sciatica” or “radiculopathy” in your medical records — what matters is the severity of impairment.
Rating criteria for sciatica
The VA rates sciatica based on the degree of sciatic nerve paralysis:
Pain and numbness alone have a cap. The peripheral nerve rules in 38 CFR § 4.124a say: “When the involvement is wholly sensory, the rating should be for the mild, or at most, the moderate degree.” If your sciatica causes only pain, numbness, or tingling — with no measurable weakness, reflex loss, or atrophy — expect 10% (mild) or at most 20% (moderate) per leg. Findings beyond wholly sensory involvement, including reflex abnormalities or weakness, may support a higher evaluation based on the overall severity; they do not automatically establish a higher tier. DC 8520 does not impose a universal motor-weakness prerequisite for 40%, while 60% expressly requires severe incomplete paralysis with marked muscular atrophy (Miller v. Shulkin, 28 Vet. App. 376 (2017)).

0% rating
Criteria: DC 8520 does not list a 0% tier. Under 38 CFR § 4.31, VA assigns 0% when diagnosed, service-connected sciatica does not meet the requirements for mild incomplete paralysis.
Monthly payment: $0 (but establishes service connection for future increases and secondary claims)
10% rating — $180.42/month
Criteria: Mild incomplete paralysis of the sciatic nerve.
What this looks like: You experience occasional shooting pain down your leg, typically triggered by certain positions or activities. Numbness or tingling comes and goes. Reflexes may be slightly reduced. You can still perform most daily activities but notice discomfort with prolonged sitting, standing, or walking. Pain may increase after physical exertion.
20% rating — $356.66/month
Criteria: Moderate incomplete paralysis of the sciatic nerve.
What this looks like: Sciatic pain is more frequent and more intense. You have consistent numbness or tingling in your leg or foot. Muscle strength is measurably reduced — the examiner can detect weakness during testing. You find yourself limiting activities to avoid triggering pain. Sitting for more than 30 minutes to an hour becomes uncomfortable. You may have altered your gait to compensate for the pain.
40% rating — $795.84/month
Criteria: Moderately severe incomplete paralysis of the sciatic nerve.
What this looks like: Severe radiating pain that occurs frequently or constantly. Significant weakness in the leg affects your ability to walk normally. You may have early signs of foot drop — difficulty lifting the front of your foot. Numbness is persistent and widespread in the affected leg. You need pain medication regularly. Physical employment is no longer feasible, and even sedentary work is compromised by the inability to sit comfortably.
60% rating — $1,435.02/month
Criteria: Severe incomplete paralysis of the sciatic nerve, with marked muscular atrophy.
What this looks like: Your affected leg is visibly thinner than the other due to muscle wasting. The calf and/or thigh muscles have atrophied from disuse and nerve damage. Pain is constant and severe. You likely have significant foot drop requiring bracing. Sensation is severely diminished. Walking requires an assistive device (cane, walker). The “marked muscular atrophy” is what distinguishes this level from the 40% rating — the examiner must document measurable muscle loss.
80% rating — $2,102.15/month
Criteria: Complete paralysis of the sciatic nerve. The foot dangles and drops, no active movement is possible of muscles below the knee, and flexion of the knee is weakened or (very rarely) lost.
What this looks like: Total loss of sciatic nerve function. Your foot hangs limp and you cannot move it in any direction. You have no active muscle control below the knee. Sensation is absent. You require a wheelchair or significant assistive devices for mobility. This is the maximum schedular rating for sciatica.
What evidence do you need?
Service records
- Service treatment records documenting back injuries, leg pain, or sciatica symptoms during service
- DD-214 showing MOS or duties with high physical demands (infantry, airborne, armor, combat engineer)
- Records of specific injuries — parachute landing falls, vehicle accidents, combat injuries, heavy lifting incidents
- Physical profiles or duty limitations related to back or leg pain
Medical evidence
- MRI of the lumbar spine — Existing MRI results may show structural causes such as a herniated disc, bone spur, or stenosis when imaging is clinically indicated. MRI is not a universal prerequisite; history and clinical findings can establish radiculopathy.
- Nerve conduction study (NCS) and electromyography (EMG) — Existing results may help assess nerve damage when clinically indicated. These tests are not a prerequisite for ratings above 10%; EMG is rarely required to diagnose radiculopathy.
- Treatment records documenting ongoing sciatic pain, physical therapy, and medications
- Surgical records if you’ve had spinal surgery (discectomy, laminectomy, spinal fusion)
- Pain management records including epidural steroid injections or nerve blocks
Nexus letter
A medical opinion connecting your sciatica to your military service or to a service-connected back condition. For secondary claims, the letter should clearly explain: “The veteran’s sciatica is at least as likely as not caused by or aggravated by his/her service-connected lumbar spine condition, as the MRI-documented disc herniation at [level] compresses the [nerve root], producing the sciatic nerve symptoms.”
Buddy statements
Statements from people who observe your daily limitations: your spouse describing how you cannot sit through dinner, coworkers noting your need to stand and stretch constantly, friends who have seen you limping or unable to participate in activities. Fellow service members can describe the physical events that contributed to your back and nerve problems.
Personal statement
Write a detailed personal account of how sciatica affects every aspect of your life. Be specific and vivid: “The pain shoots from my lower back down to my left foot like an electric shock. It happens dozens of times per day. I cannot drive more than 15 minutes because sitting in a car seat makes the pain unbearable. I sleep on the floor because my bed aggravates the nerve. I had to quit my job as a [occupation] because I could not [specific task].”
C&P exam tips for sciatica
What the examiner evaluates
- Straight leg raise test — the primary clinical test for sciatica
- Muscle strength testing in the affected leg (hip flexion, knee extension/flexion, ankle dorsiflexion, ankle plantar flexion, great toe extension)
- Deep tendon reflexes (knee and ankle)
- Sensory testing along the sciatic nerve distribution
- Gait assessment — limping, use of assistive devices, foot drop
- Measurement of leg circumference to assess for muscle atrophy
- Review of MRI findings showing nerve compression
- Review of nerve conduction study results
- Classification of paralysis as incomplete (mild, moderate, moderately severe, severe) or complete
How to prepare
- Submit existing imaging if available. Ask your clinician whether additional imaging is needed; follow your scheduled exam instructions without delaying attendance to obtain an MRI.
- Discuss testing with your clinician. Submit existing NCS/EMG results if available, and obtain or repeat testing only when clinically indicated.
- Keep taking your medications as prescribed. Don’t stop medication for the exam. Instead, tell the examiner which symptoms remain despite medication, on typical days and during flare-ups. Use only events that are true for you.
- Walk naturally to the exam room. If you limp, let the examiner see it. If you use a cane, bring it.
- Describe the full impact. Don’t just say “my leg hurts.” Explain that you cannot sit for meetings at work, cannot drive your children to school, cannot sleep through the night, and have fallen because your leg gave out.
- Mention both legs if affected. Each leg is rated separately, so ensure both are evaluated.
Common mistakes
- Not describing current symptoms and functional limitations or submitting existing relevant records
- Telling the examiner you’re “managing” or “dealing with it” — this minimizes severity
- Not mentioning weakness, numbness, and balance problems (focusing only on pain)
- Failing to report how symptoms change with activity — describe what makes it worse and how long flare-ups last
- Not connecting sciatica to your service-connected back condition when filing secondary
- Not telling the examiner how much your medication helps and which symptoms remain despite it
Common secondary conditions linked to sciatica
Sciatica commonly causes or aggravates other conditions that may qualify for separate VA ratings:
- Depression — Chronic sciatic nerve pain is strongly linked to depression. The constant pain, sleep disruption, loss of mobility, and impact on employment erode mental health over time.
- Sleep apnea — Reduced physical activity due to sciatica leads to weight gain, which is a primary risk factor for obstructive sleep apnea. Pain-related sleep disturbances further compound the problem.
- Erectile dysfunction — The lumbar nerve roots that form the sciatic nerve are adjacent to the nerves controlling sexual function. Compression in the lumbar spine can affect both. Additionally, pain medications commonly prescribed for sciatica (opioids, gabapentin) frequently cause erectile dysfunction.
- Anxiety — The unpredictability of sciatic pain episodes, fear of the condition worsening, and worry about loss of employment contribute to anxiety disorders.
- Bladder and bowel dysfunction — Severe sciatica involving the lower sacral nerve roots can cause neurogenic bladder or bowel problems, including urgency, frequency, or incontinence.
How to calculate your monthly payment
Your total VA disability payment depends on your combined rating across all service-connected conditions. Sciatica is most commonly rated alongside a back condition, and veterans frequently have additional secondary conditions that increase the combined rating further.
For example, a veteran rated 20% for a back condition with 20% sciatica in each leg (bilateral) and 30% for depression could achieve a significantly higher combined rating than the back condition alone.
Use our VA disability calculator to:
- Calculate your combined rating with back pain, bilateral sciatica, and secondary conditions
- See how VA math combines ratings and applies the bilateral factor for paired extremities
- Estimate your monthly payment including dependents

Correction — October 21, 2026: Removed the claim that ratings of 40% and higher require motor involvement, keeping the sensory-only cap and the 60% atrophy requirement. Clarified that sciatica can come from nerve roots or the sciatic nerve itself. Replaced advice to get an MRI and nerve study before the exam with submitting existing results. Clarified that for IVDS (DC 5243), separate nerve ratings are added only under the General Rating Formula, not to an incapacitating-episodes rating.

Frequently Asked Questions
What is the difference between sciatica and radiculopathy?
Sciatica refers specifically to pain along the sciatic nerve pathway — from the lower back through the hip and buttock and down the back of the leg. Radiculopathy is a broader term for any nerve root compression. Sciatica commonly results from lumbosacral root irritation, but can also arise from the sciatic nerve outside the spine. The sciatic nerve is formed from roots L4–S3. The VA rates both under the same diagnostic code (DC 8520).
Can I claim sciatica as secondary to my back condition?
Yes. Sciatica is one of the most commonly granted secondary conditions. If you have a service-connected back condition (lumbosacral strain, degenerative disc disease, herniated disc), sciatica caused by that condition qualifies for secondary service connection. You can receive a separate rating for the sciatic nerve in addition to your spinal rating. Exception: if VA rates intervertebral disc syndrome (DC 5243) by incapacitating episodes, separate nerve ratings are not added to that rating.
What is the maximum VA rating for sciatica?
The maximum schedular rating for sciatica under DC 8520 is 80% for complete paralysis of the sciatic nerve. This requires total loss of function — the foot dangles and drops, no active movement below the knee, and knee flexion is weakened or lost.
Does the VA rate sciatica in both legs separately?
Yes. Each affected leg receives its own rating. If you have bilateral sciatica, you get two separate ratings that combine using VA math. The bilateral factor (an additional 10% of the combined bilateral value) also applies, giving you a higher combined rating.
How do I prove my sciatica is service-connected?
You need to show either a direct connection to military service or a secondary connection to an existing service-connected condition. Most veterans claim sciatica as secondary to a back condition. An MRI showing nerve root compression, a nerve conduction study documenting nerve damage, and a nexus letter connecting the sciatica to service or a service-connected condition form the strongest evidence package.
