Sciatica VA Disability Rating: Criteria, Evidence & Pay

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.

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 at six possible levels based on the degree of sciatic nerve paralysis:

0% rating

Criteria: Sciatica has been diagnosed and service-connected, but current symptoms are minimal and do not meet the criteria 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 — $2,102.32/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 — This is critical. An MRI shows the structural cause of your sciatica (herniated disc, bone spur, stenosis compressing the nerve root). Without imaging, the VA may question whether true nerve compression exists.
• Nerve conduction study (NCS) and electromyography (EMG) — These tests objectively measure how well the sciatic nerve conducts signals and can quantify the severity of nerve damage. Highly recommended for claims above 10%.
• 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

1. Get an MRI if you don’t have one. The MRI provides the structural evidence showing why your sciatic nerve is being compressed. Without it, the VA may rate your condition lower.
2. Consider a nerve conduction study. An NCS/EMG provides objective, measurable evidence of nerve damage that supports higher ratings.
3. Don’t take pain medication before the exam. You want the examiner to see your actual symptom level.
4. Walk naturally to the exam room. If you limp, let the examiner see it. If you use a cane, bring it.
5. 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.
6. Mention both legs if affected. Each leg is rated separately, so ensure both are evaluated.

Common mistakes

• Not getting an MRI — this is the foundation of a strong sciatica claim
• 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
• Taking heavy pain medication before the exam, which masks symptoms during testing

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
