Sciatic nerve paralysis / sciatica VA Rating

Sciatic nerve paralysis / sciatica is rated under diagnostic code 8520. In the VA Schedule for Rating Disabilities it appears as Sciatic nerve, within the Neurological Conditions section of 38 CFR Part 4.

The essentials

Other names for this condition

VA and treating providers may use different terms for the same condition. If your records use any of these, they may still support a claim for Sciatic nerve paralysis / sciatica:

• Sciatica
• sciatic nerve pain

What evidence decides the rating

For neurological conditions conditions, these are the findings VA weighs when assigning a percentage. If your examination did not address them, the examination may be inadequate for rating purposes — which is itself an argument on appeal.

• Which specific nerve is involved and whether impairment is complete or incomplete paralysis
• Whether symptoms are wholly sensory — that caps the rating at mild or moderate under the nerve codes
• For migraines: frequency of prostrating attacks and whether they are productive of severe economic inadaptability (DC 8100)
• For seizures: witnessed episode frequency over the preceding six and twelve months
• For TBI: the facets table under DC 8045, scored individually

Why these claims get denied or under-rated

These are the failure patterns we see most often on sciatic nerve paralysis / sciatica and related neurological conditions claims:

• Radiculopathy rated as wholly sensory when the record documents weakness or reflex loss
• Migraine denied as not prostrating because the veteran keeps working — the criterion is severe economic inadaptability, not unemployment
• Headache frequency was recorded from memory at one appointment rather than from a headache diary
• TBI residuals rated as a single evaluation instead of scoring each facet under DC 8045

Secondary service connection

Under 38 CFR §3.310, a condition caused or aggravated by an already service-connected condition is itself service-connected. Secondary claims are where most veterans are leaving compensation on the table — and where most denials turn on the nexus opinion rather than the diagnosis.

Sciatic nerve paralysis / sciatica is commonly claimed secondary to

• Low back strain
• Intervertebral disc syndrome
• Spinal stenosis
• Piriformis syndrome

Sciatic nerve paralysis / sciatica commonly causes or aggravates

• Falls
• Insomnia
• Depression from chronic pain

If you are already service-connected for sciatic nerve paralysis / sciatica and any of these apply to you, they may be claimable as secondary conditions.

If your claim was denied or under-rated

A denial is not the end of the claim. Which route is right depends on why VA decided the way it did:

• Higher-Level Review — when the evidence already in the file supports a grant and VA got the decision wrong, or the examination was inadequate.
• Supplemental Claim — when you have new and relevant evidence, such as a private nexus opinion.
• Board Appeal — when you need a Veterans Law Judge to decide, or want a hearing.
• Clear and Unmistakable Error — when a decision more than a year old contains an undebatable error, which can recover retroactive pay.

Effective dates matter as much as the percentage. See effective dates and back pay for how far back an award can reach.
