Paralysis of the Sciatic Nerve VA disability rating & claim guide

Yes. The VA rates Paralysis of the Sciatic Nerve under VASRD diagnostic code 8520 (Neurological Conditions). Damage to the sciatic nerve that causes leg weakness, pain, or paralysis.

Possible VA ratings for Paralysis of the Sciatic Nerve are 80%, 60%, 40%, 20%, 10%, 0%. The 0% level comes from 38 CFR 4.31, which assigns it wherever no compensable level is met. Examples: 80%: Complete; the foot dangles and drops, no active movement possible of muscles below the knee, flexion of knee weakened or (very rarely) lost; 60%: Incomplete paralysis: severe, with marked muscular atrophy; 40%: Incomplete paralysis: moderately severe.

Vetrify estimates the typical rating awarded for Paralysis of the Sciatic Nerve at around 40%, based on VA claims data and the rating schedule. Per the VBA Annual Benefits Report (FY2025), veterans receiving VA compensation as of September 30, 2025 had 2,026,583 service-connected disabilities rated as Paralysis of the Sciatic Nerve. The report counts disabilities, not veterans. Estimated approval outlook: High if symptoms are persistent and confirmed by EMG or physical exam.

Strong evidence for a Paralysis of the Sciatic Nerve claim includes: EMG or nerve conduction study showing sciatic involvement; Neurologist report describing motor/sensory deficits; Functional assessment showing gait or mobility loss.

VA's Peripheral Nerves Disability Benefits Questionnaire (DBQ) is on its public list of DBQs. VA's Diabetic Peripheral Neuropathy Disability Benefits Questionnaire (DBQ), for diabetic sensory-motor peripheral neuropathy, which VA's Peripheral Nerves form excludes, is on its public list of DBQs. VA's page says: "You can use these forms to submit medical evidence from your health care providers."

Common pitfalls when filing for Paralysis of the Sciatic Nerve: Failing to distinguish between complete and incomplete paralysis; No EMG or diagnostic evidence; Not detailing functional limitations in walking or standing.

Conditions that can be service-connected as secondary to Paralysis of the Sciatic Nerve, when a medical opinion links them, include: Depression. A secondary condition gets its own rating, which VA combines with the veteran's other ratings under 38 CFR 4.25.

There is no diagnostic code called sciatica, and the word does not appear in 38 CFR Part 4. Sciatica describes what a nerve is doing; the schedule rates the nerve. Radiating pain, numbness or weakness in the distribution of the sciatic nerve is evaluated on the DC 8520 scale, which runs from mild incomplete paralysis through moderate, moderately severe and severe with marked muscular atrophy, up to complete, where the foot dangles and drops and no active movement is possible below the knee. Which step applies comes from the motor, reflex and sensory findings recorded at the examination.

Yes, and the schedule directs it. Note (1) of the General Rating Formula for Diseases and Injuries of the Spine says to evaluate any associated objective neurologic abnormality separately, under an appropriate diagnostic code. A nerve evaluation is therefore not part of the spine percentage: it is its own evaluation, combined with the spine one under 38 CFR 4.25. The word "objective" is the part that decides it, so the examination has to record findings, not only a report of pain. Both legs can be evaluated, each on its own.
