Home › Conditions › Radiculopathy
Nerve-root pain, numbness or weakness radiating into an arm or leg — rated per extremity, on top of the spine rating. This guide quotes the actual rating criteria from 38 CFR Part 4 for diagnostic code 8520 sciatic / 8510-13 upper, explains what the C&P examiner measures, covers the presumptive and secondary routes to service connection, and lists the reasons these claims come back denied — and how each gets fixed.
How the VA rates radiculopathy in 2026 — the exact criteria
These are the criteria a VA rater applies, quoted from the rating schedule (§ 4.124a). Your rating is the highest level whose wording your evidence meets — and evidence that never uses these words tends to be rated at the bottom.
DC 8520 — Sciatic nerve (paralysis of)
| Rating | Criteria (38 CFR Part 4 wording) |
|---|---|
| 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 — severe, with marked muscular atrophy |
| 40% | Incomplete — moderately severe |
| 20% | Incomplete — moderate |
| 10% | Incomplete — mild |
Each extremity is rated separately and then combined — two legs is two ratings.
The upper-extremity nerves (DC 8510 upper radicular group, 8511 middle, 8512 lower, 8513 all radicular groups) follow the same complete/severe/moderate/mild ladder, with major-hand and minor-hand values (for example DC 8510: complete 70/60, severe 50/40, moderate 40/30, mild 20/20).
Honest ceiling: 40% for moderately severe nerve involvement.
What the C&P examiner measures
The DBQ grades each nerve as mild, moderate, moderately severe or severe from sensation, reflexes, strength and atrophy — and records constant pain, intermittent pain, paresthesias and numbness per extremity. Tell the examiner exactly where the numbness runs (which leg, to the foot, which toes) and what it stops you doing.
The questions that get at the rating criteria — answer them for yourself before the exam:
- Does anything shoot down your leg — like electric, or pins and needles?
- Does either leg ever give out or go numb?
- Is it one leg or both? They rate separately.
Service connection: presumptive, direct, or secondary
No presumption of its own. Radiculopathy is rated as a separate neurologic abnormality of a service-connected spine condition (General Rating Formula for the Spine, Note 1) — once the back or neck is connected, the radiculopathy rides on it.
Every service-connection claim has three legs: a current diagnosis (the C&P exam can supply it), an in-service event, injury, exposure or an already-connected condition, and a link between the two — which the VA's own examiner addresses at the exam for direct and secondary claims, and which the law supplies for presumptive ones. You do not need a private opinion to file; you need one only if the VA denies for lack of nexus, and a supplemental claim within one year keeps your effective date.
Secondary conditions veterans miss
This condition is more often the secondary in a chain than the anchor — see the secondary-claims guides for the recognized pathways.
What the medical literature says
North American Spine Society, Clinical Guideline: Diagnosis and Treatment of Lumbar Disc Herniation with Radiculopathy (2012)
Radiculopathy is a recognized direct neurological consequence of lumbar disc/spine pathology. Why it matters: Radiculopathy secondary to the service-connected spine.
Why radiculopathy claims get denied — and the fix
- Rated "mild" when strength, reflex and sensory findings supported moderate — the DBQ findings were not read against the criteria.
- Only one extremity rated when both had symptoms.
A denial is a grade on the evidence packet, not a verdict on you. Filed as a supplemental claim within one year, the fix keeps your original effective date.
Filing it right the first time
- Intent to File first. It locks your effective date for a year — back pay runs from that day, not from the day the package is ready.
- File everything at once. Every condition with a real symptom and a plausible route — direct, presumptive, secondary, increase — goes in one claim. The VA's duty to assist schedules the exam and pulls your records; a condition held back "for more evidence" only starts its clock later.
- Your statement in the criteria's words. A Statement in Support of Claim (VA Form 21-4138) that describes your worst days and your typical days using the language in the table above is the evidence the rater reads first.
- Your records. VA records through Blue Button, decision letters and code sheet from VA.gov, and private records from each doctor's office or patient portal — or a signed 21-4142 so the VA pulls them.
- Prepare for the exam. Know what the examiner measures (above) and answer honestly, including the bad days.

What is the VA rating for radiculopathy?
Radiculopathy is rated under diagnostic code 8520 sciatic / 8510-13 upper (§ 4.124a) at 10%, 20%, 40%, 60%, 80%. The percentage depends on which criteria in the rating schedule your evidence meets — the full table is on this page.
What is the highest VA rating for radiculopathy?
The highest schedular rating available is 80%. Typical grants land around 10%, but every case is decided on its own evidence.
Is radiculopathy a presumptive condition?
No presumption of its own. Radiculopathy is rated as a separate neurologic abnormality of a service-connected spine condition (General Rating Formula for the Spine, Note 1) — once the back or neck is connected, the radiculopathy rides on it.
Do I need a nexus letter for radiculopathy?
Not to file. The VA's duty to assist schedules a C&P exam where its own examiner addresses the connection, and presumptive conditions need no opinion at all. A private opinion becomes worth buying only if the VA denies for lack of nexus — a supplemental claim within one year keeps your original effective date.
