How the VA Rates Sciatica
Sciatica does not have its own diagnostic code in the VA's rating schedule. Instead, the VA rates sciatica (irritation or compression of the sciatic nerve, usually from a lumbar spine condition) under Diagnostic Code 8520 (38 CFR §4.124a, “Paralysis of the sciatic nerve”), the same code used for other sciatic nerve conditions. Ratings depend on the severity of nerve impairment, described as incomplete or complete paralysis.
Diagnostic Code 8520: Rating Criteria
- 80%: complete paralysis: the foot dangles and drops, no active movement of muscles below the knee, flexion of the knee weakened or (very rarely) lost.
- 60%: severe incomplete paralysis, with marked muscular atrophy.
- 40%: moderately severe incomplete paralysis.
- 20%: moderate incomplete paralysis.
- 10%: mild incomplete paralysis.
“Incomplete paralysis” covers the range from mild sensory changes to nearly complete nerve loss, and the VA rater's job is to place your specific symptoms (pain, numbness, tingling, weakness) on that scale using the exam findings.
Sciatica Is Usually Rated as Part of Your Back Condition
Because sciatica is a symptom of nerve root involvement rather than a standalone disease, it is very often rated separately from, but alongside, a lumbar spine condition. The VA rates the orthopedic (spine) impairment under the General Rating Formula for the Spine, and any associated radiculopathy (sciatica) as a distinct neurological rating under DC 8520, then combines the two using the combined ratings table. This is why many veterans see “radiculopathy” rather than “sciatica” on their rating decision; they describe the same nerve involvement. See our lower extremity radiculopathy page for the companion rating path.
Secondary conditions to sciatica
Chronic sciatic pain can lead veterans to change how they walk or stand to avoid triggering symptoms, and that gait compensation can produce or aggravate knee and hip pain over time — a pattern worth documenting if you already have a sciatica or radiculopathy rating. Persistent nerve pain is also commonly linked to secondary insomnia, anxiety, or depression, especially when it limits mobility or sleep. If you notice any of these downstream symptoms, mention them in a personal statement and ask your provider to document them at your next visit.
Evidence: Nerve and Spine Findings
- Physical exam findings such as decreased sensation, reflex changes, or a positive straight-leg-raise test.
- Electrodiagnostic testing (EMG/nerve conduction study) when the diagnosis is in question or the severity level is disputed.
- Imaging (MRI/CT) of the lumbar spine showing a herniated or bulging disc pressing on a nerve root, if sciatica is linked to a spine condition.
- A description of how far pain, numbness, or weakness radiates down the leg, and whether it affects walking, standing, or foot control.
Nexus: Connecting Sciatica to Military Service
- Secondary to a service-connected back condition: the most common path: a nexus letter or medical opinion linking your sciatic nerve symptoms to your already-rated lumbar spine condition.
- Direct service connection: service treatment records documenting sciatic-type leg pain, numbness, or a back injury with radiating symptoms during service.
What to Expect at Your C&P Exam
- The examiner will test sensation, reflexes, and muscle strength along the sciatic nerve distribution (buttock, back of thigh, calf, foot).
- Describe whether symptoms are constant or intermittent, and how they affect walking or standing.
- Mention any muscle wasting (atrophy) you or your doctor have noticed, since this affects where you land on the incomplete-to-complete paralysis scale.
2026 Monthly Compensation Amounts
A 10% VA rating for sciatica pays $180.42 per month (2026 rate, veteran alone, no dependents). A 20% rating pays $356.66/month, a 40% rating pays $795.84/month, and a 60% rating pays $1,435.02/month. See the full 2026 VA compensation rate chart.
