That shooting, electric pain that runs from your back down a leg, or from your neck into an arm, is radiculopathy. A nerve root in the spine is pinched, and the pain, numbness, and weakness travel down the limb. Sciatica is the name for it in the leg. For most veterans it rides along with a service-connected back or neck condition, and it can be rated on top.
A nexus letter makes the connection. Our physicians tie the nerve pain to your spine condition, and to your service, in the language the VA expects. One flat fee of $1,500, and the first consultation is free.
How VA Rates Radiculopathy
Radiculopathy is rated under 38 C.F.R. § 4.124a, by the nerve it travels down. Pain down the leg (sciatica) is rated on the sciatic nerve, DC 8520, and that scale is shown below. Pain into the arm or neck (cervical radiculopathy) is rated on the cervical nerve groups, DC 8510 to 8513, which use a different scale. That difference is explained right under the table.
| Rating | What it generally takes | Monthly pay (approx) |
|---|---|---|
| 80% | Complete paralysis. The foot dangles and drops, with no real movement below the knee. | ~$2,102/mo |
| 60% | Severe, with marked muscle wasting in the leg. | ~$1,435/mo |
| 40% | Moderately severe nerve involvement. | ~$796/mo |
| 20% | Moderate. Clear radiating pain, numbness, and some weakness down the leg. | ~$357/mo |
| 10% | Mild. Radiating pain or numbness down the leg, without much weakness. | ~$180/mo |
Radiculopathy is rated on top of the back or neck condition it comes from, not instead of it. Each affected limb is rated on its own, so pain down both legs can carry two ratings, which then combine with the spine rating. The table above is the leg (sciatic, DC 8520) scale. Arm and neck radiculopathy is rated on the cervical nerve groups, DC 8510 to 8513, which work differently: instead of one severity ladder, they use two columns, one for the dominant (writing) arm and one for the non-dominant arm. Their ceilings are lower than the leg's, roughly 60 to 70 percent for a single nerve group, up to 90 percent for DC 8513, which covers all the arm nerve groups together. At the mild level both arms rate the same. So the 80 percent ceiling in the table above is the leg scale, not the arm scale. If the symptoms are all sensory (pain and numbness, no real weakness), the rating is usually mild, or at most moderate.
Pay figures are approximate 2026 rates (effective December 1, 2025) for a single veteran with no dependents. Check VA.gov for current amounts.
Making a VA Disability Claim for Radiculopathy and Sciatica
A VA disability claim for radiculopathy usually rests on three things:
A current diagnosis
A diagnosis of radiculopathy or sciatica, often backed by an MRI showing nerve-root compression and a nerve test.
A service connection
Almost always a link to a service-connected back or neck condition that is pinching the nerve.
A medical nexus
A qualified opinion that the radiculopathy is 'at least as likely as not' caused by the service-connected spine condition.
Radiculopathy is a common secondary claim veterans miss. If your back or neck is service-connected, the nerve pain running down your limb often should be too. A nexus letter supplies the opinion linking them. The 'at least as likely as not' standard (a 50% or better chance) comes from the benefit-of-the-doubt rule in 38 U.S.C. § 5107(b), carried out in 38 C.F.R. § 3.102.
How to Connect Radiculopathy and Sciatica to Service
Radiculopathy is almost always tied to the spine. The secondary path, through a service-connected back or neck, is the usual route.
Secondary connection
A service-connected spine condition is pinching the nerve (38 C.F.R. § 3.310).
- A service-connected back. A lumbar spine condition can pinch the sciatic nerve and send pain down the leg.
- A service-connected neck. A cervical spine condition can pinch a nerve and send pain into the arm.
Direct connection
The nerve was injured or pinched in service.
- A spine injury. An in-service back or neck injury that hit the nerve root directly and caused radiating pain.
Aggravation
You had radiating nerve pain before service, and service made it permanently worse.
- Worsened by service. The radiating pain got worse during active duty, beyond normal change over time.
Secondary Conditions
Radiculopathy sits between the spine and the limb. It comes from a back or neck condition, and the lost function can lead to problems of its own.
Radiculopathy may be secondary to
- A back condition. A service-connected lumbar spine condition is the most common cause of sciatica down the leg.
- A neck condition. A service-connected cervical spine condition can send nerve pain into the arm.
Conditions that may follow radiculopathy
- Falls and injuries. Leg weakness and numbness make falls more likely.
- An altered gait. Favoring a painful leg can strain the other joints over time.
- Depression or anxiety. Chronic radiating pain wears on mood and can be claimed as secondary.
What to Gather - Evidence Checklist
Gather these before you file or ask for a letter. For radiculopathy, the imaging and the link to your spine condition carry the claim.
Frequently Asked Questions
How does the VA rate sciatica?
By the nerve it runs down, under 38 C.F.R. 4.124a. Sciatica in the leg is usually rated on the sciatic nerve (DC 8520), from 10% for mild up to 80% for complete paralysis. It is rated on top of the back condition that causes it.
Is radiculopathy a separate rating from my back?
Yes. The back or neck condition is rated under the spine rules, and the radiculopathy is rated separately on the nerve. They then combine, which is why catching it matters.
What is the difference between radiculopathy and peripheral neuropathy?
Radiculopathy starts at the spine: a pinched nerve root sends pain down one limb, usually from a back or neck condition. Peripheral neuropathy is broader nerve damage, often from diabetes or toxic exposure, and it usually affects both sides, like both feet. They are rated on the same nerve scale but have different causes.
Can both legs be rated?
Yes. Radiculopathy is rated limb by limb. Pain down both legs can carry two separate ratings, which combine with your spine rating.
Do I need a nexus letter?
Often, yes, to tie the radiculopathy to your service-connected back or neck. A nexus letter supplies that link, and it is usually what decides a secondary claim.
What does it cost, and how do we start?
Patriot Path charges $1,500 flat for a nexus letter, and the first consultation is free. Book a consultation and a clinician will tell you straight whether a letter can help your claim.
If your back is service-connected, the nerve pain may be too.
Let our physicians prepare a radiculopathy nexus letter that meets the VA's evidence standards and supports the benefits you earned.
