Neurological
Radiculopathy (Sciatic, Femoral & Cervical Nerve)
Nerve pain radiating from the spine into the arms and legs, rated under §4.124a
Radiculopathy is nerve pain, numbness, or weakness that radiates from a pinched spinal nerve into the limbs. It is rated separately from your back or neck under §4.124a — and femoral (anterior crural) radiculopathy under Code 8526 is one of the most frequently missed secondary ratings.
Each Condition, Broken Out
Every Condition In This Category Has Its Own Page
These are separate diagnostic codes with separate criteria, separate exams and separate money. Each one below opens a full page: how it is rated, the schedule spelled out, the service-connection arguments, and exactly what happens at that specific C&P exam.
DC 8510–8513
Cervical Radiculopathy — Upper Extremity Nerve Root Compression
A nerve root pinched in your neck sends pain, numbness and weakness down the shoulder, arm and into the hand.

DC 8520
Sciatica — Sciatic Nerve Radiculopathy of the Lower Extremity
A nerve root pinched in your low back sends pain, numbness and weakness down the buttock, the back of the thigh, the calf and into the foot.

DC 8526
Femoral Radiculopathy — Anterior Crural Nerve Involvement of the Lower Extremity
A nerve root pinched at L2, L3 or L4 sends pain, numbness and quadriceps weakness down the FRONT of the thigh to the knee — and almost nobody asks about it.

What Radiculopathy (Sciatic, Femoral & Cervical Nerve) Really Is
Radiculopathy is what happens when a nerve leaving your spine gets pinched. The pain does not stay in your back. It shoots down a leg or an arm, and it brings numbness, tingling, burning, and weakness with it. This matters enormously in a VA claim because the nerve is rated separately from the spine, and that separate rating is the money most veterans leave behind.
What it actually means
Radiculopathy is what happens when a nerve leaving your spine gets pinched. The pain does not stay in your back. It shoots down a leg or an arm, and it brings numbness, tingling, burning, and weakness with it. This matters enormously in a VA claim because the nerve is rated separately from the spine, and that separate rating is the money most veterans leave behind.
What the VA measures
Radiculopathy is rated under the peripheral nerve codes in 38 CFR 4.124a by the affected nerve and the degree of paralysis: mild, moderate, moderately severe, or severe incomplete paralysis, up to complete paralysis. The sciatic nerve code 8520 for the lower extremity and the radial, median, and ulnar codes for the upper extremity are the ones you see most.
Why claims get missed
The regulation for the spine says to rate any associated objective neurologic abnormality separately under the appropriate diagnostic code. That sentence is worth thousands of dollars a year and is skipped constantly. Bilateral radiculopathy means two separate ratings plus the bilateral factor. Sensory-only involvement is capped at the mild level, so documented weakness and reflex loss are what push you higher.
What in Your Service Causes Radiculopathy (Sciatic, Femoral & Cervical Nerve)
Service connection is not a feeling, it is a chain of evidence. These are the pathways the VA already recognises. Find yours, then make sure your file says it out loud.
Service-connected spine degeneration
Disc herniation, foraminal narrowing, and spondylosis from years of load-bearing duty compress the nerve root. This is the dominant path and it is secondary to the spine condition you already have.
Acute in-service injury
A documented lifting injury, fall, parachute landing, or vehicle accident that produced radiating symptoms at the time.
Rucksack, gear, and vehicle vibration
Decades of asymmetric load and whole-body vibration accelerate the degeneration that pinches nerves.
Diabetic and toxic contribution
A service-connected metabolic condition lowers the threshold at which nerve compression becomes symptomatic.
A Separate Rating From Your Spine
Radiculopathy is not part of your back or neck rating — it is a distinct neurological disability under §4.124a. When a service-connected spine condition pinches a nerve root, the resulting radiating symptoms are rated secondarily under §3.310. Each affected nerve, in each limb, on each side, carries its own rating, and those ratings combine on top of your spine evaluation. Veterans rated only for the spine are routinely leaving several of these ratings unclaimed.
Femoral (Anterior Crural) Radiculopathy — The One They Miss
Most veterans and even representatives think “radiculopathy” means sciatica — pain down the back of the leg. But nerve compression at the upper lumbar levels produces femoral radiculopathy, rated under Code 8526, with pain, numbness, and weakness down the front of the thigh and into the knee. It is real, it is ratable, and it is missed constantly because the exam never asks about the front of the leg. If your symptoms travel down the front of your thigh, say so.
How Severity Is Graded
Mild, moderate, moderately severe, or severe incomplete paralysis
Complete paralysis (e.g., foot drop for the sciatic nerve)
Rated per nerve, per limb, per side — ratings combine
Objective findings: reflexes, sensation, motor strength, EMG
Establishing Service Connection
To establish service connection for a neurological condition, veterans must meet three criteria. First, there must be a current diagnosis. Second, there must be evidence of an in-service injury, event, or exposure that could have caused or aggravated it — including head trauma, blast exposure, or an underlying service-connected condition. Third, a nexus — a medical link — must connect the in-service event to the current condition.
Current diagnosis of the neurological condition
In-service injury, event, or exposure (or a service-connected primary condition)
Medical nexus linking the condition to service ("at least as likely as not")
Records documenting frequency and severity of neurological symptoms
Imaging or specialist evaluation where available

The Rating Schedule, Spelled Out
Radiculopathy is nerve damage rated under 38 CFR §4.124a as “incomplete paralysis” of the affected nerve, graded mild, moderate, moderately severe or severe, up to complete paralysis. Lumbar radiculopathy usually runs through the sciatic nerve (Diagnostic Code 8520) or femoral nerve (Diagnostic Code 8526); each affected extremity is rated separately.
Mild incomplete paralysis.
Moderate incomplete paralysis.
Moderately severe incomplete paralysis.
Severe incomplete paralysis, with marked muscular atrophy.
Complete paralysis; the foot dangles and drops, no active movement is possible of the muscles below the knee, and flexion of the knee is weakened or lost.
Mild incomplete paralysis.
Moderate incomplete paralysis.
Severe incomplete paralysis.
Complete paralysis of the quadriceps extensor muscles.
Key Points to Remember
Rated under 38 CFR §4.124a by the nerve affected — sciatic (DC 8520), femoral (DC 8526), and others
Mild, moderate, moderately severe, and severe incomplete paralysis set the levels
Usually secondary to a service-connected spine condition (§3.310)
Document radiating pain, numbness, tingling, and any muscle weakness
What to Expect at Your Radiculopathy C&P Examination
Radiculopathy is rated on adjectives — mild, moderate, moderately severe and severe incomplete paralysis — and those adjectives are supposed to come from objective findings, not from how well you describe the pain. Under 38 CFR §4.124a each extremity is rated separately, and when the involvement is wholly sensory the rating is capped at mild or at most moderate. That single sentence in the regulation is why strength, reflex and atrophy testing matter more than anything else you say at this exam.
Muscle strength graded 0 to 5 in every affected myotome, both sides, not just the painful one.
Deep tendon reflexes graded 0 to 4+ — biceps, triceps and brachioradialis for cervical roots; patellar and Achilles for lumbar roots.
Dermatome-by-dermatome sensory mapping to light touch and pinprick, with each level scored normal, decreased or absent.
Limb circumference measured in centimeters at a fixed landmark on both sides to document muscle atrophy — marked atrophy is what supports the higher levels.
Provocative testing: straight-leg raise and femoral stretch for the lumbar spine, Spurling test for the cervical spine, with the angle or position of symptom reproduction recorded.
Review of EMG and nerve conduction studies and correlation of the findings to a specific nerve root and MRI level.
An explicit statement of whether the involvement is wholly sensory, whether the picture is paralysis, neuritis or neuralgia, and the severity in the regulation’s own words for EACH extremity.
What Happens Once the C&P Exam Is Complete
The examiner compiles a detailed report — your medical history, physical findings, and diagnostic results — and assesses the severity, symptoms, and impact of your condition. That report is sent to the VA Regional Office handling your claim and becomes part of your official file, reviewed alongside your other evidence.
The VA may send the report back for corrections, clarification, or a second opinion if it finds it incomplete or unclear. This can delay your claim, because the VA requires thorough and accurate information to decide. Your claim only moves to the decision phase once the VA is satisfied with the evidence — which is exactly why the quality of the file we build for you matters so much. Once decided, your effective date controls how far back your back pay reaches, and any denial can be challenged through a Supplemental Claim, Higher-Level Review, or Board appeal.
The Advocate’s Take
If your back is service-connected and you have shooting pain, numbness, or weakness in either leg or arm — especially down the front of the thigh — you likely have unclaimed femoral or sciatic radiculopathy ratings sitting on the table.
Every Level the VA Can Assign You
These percentages come straight out of the rating schedule that governs radiculopathy (sciatic, femoral & cervical nerve) — Diagnostic Code 8520. Read them slowly. If your current rating does not match what your records actually show, that gap is exactly what an appeal exists to correct.
10%
Mild incomplete paralysis.
20%
Moderate incomplete paralysis.
40%
Moderately severe incomplete paralysis.
60%
Severe incomplete paralysis, with marked muscular atrophy.
80%
Complete paralysis;
Secondary Claims — Both Directions
Under 38 CFR §3.310, a condition caused or made worse by an already service-connected condition is itself service connected. That runs in both directions, and it is the single largest pool of unclaimed compensation in the system.
What can cause radiculopathy (sciatic, femoral & cervical nerve)
If one of these is already service connected, this condition can be claimed as secondary to it.
Lumbar or cervical spine condition
The single most common route. The regulation directs a separate neurologic rating.
Diabetes
Diabetic nerve disease and compressive radiculopathy compound each other.
Post-surgical scarring
Fibrosis after spine surgery can entrap the nerve root.
What radiculopathy (sciatic, femoral & cervical nerve) can cause
If this condition is already service connected, each of these is a separate claim you may be owed.
Foot drop and gait abnormality
Motor loss changes how you walk and produces new joint claims.
Knee, hip, and ankle strain
Altered gait overloads the joints on both sides.
Falls and secondary injury
Weakness and numbness cause documented falls.
Depression, anxiety, and sleep loss
Neuropathic pain at night is a recognized driver.
A secondary claim still needs two things: a current diagnosis of the secondary condition, and a medical opinion saying it is at least as likely as not caused or aggravated by the service-connected condition. You do not have to prove it happened in service.
Building a Radiculopathy (Sciatic, Femoral & Cervical Nerve) Claim That Wins
Every claim stands on three legs. Knock one out and the claim falls over, no matter how bad your symptoms are. Before you file, look at your file and find all three.
A current diagnosis
A doctor has to say you have it, now, in writing. Not "reports symptoms of" — a diagnosis. Without this leg, nothing else in the file matters.
A link to your service
An event, an injury, an exposure, or an already service-connected condition. Service records, unit records, buddy statements, and your own account all count as evidence.
A nexus that ties the two together
A medical opinion stating it is at least as likely as not that your service caused or aggravated the condition. That phrase is a legal standard: 50 percent or better. It is the leg most denials break.
Document the problem before you file
• Keep a dated symptom log for at least 30 days. Frequency, severity, and what it stopped you from doing.
• Get statements from people who see it — a spouse, a coworker, a battle buddy. Lay evidence is legal evidence.
• Pull your private treatment records. The VA only has to help; it does not have to go find everything.
• Write down what you have stopped doing. Lost work, lost sleep, lost activities. That is what impairment looks like on paper.
Your Rights in This Process
It costs nothing to file
Filing a VA claim is free. Accredited representatives may only charge for work on an appeal after an initial decision, and those fees are capped by 38 CFR §14.636.
The VA has a Duty to Assist you
Under 38 CFR §3.159 the VA must help you get the evidence it needs, and it must tell you what is missing before it denies you for missing it.
You can ask for a different examiner
You may request a trauma-informed clinician, or a clinician of a specific gender, for a C&P examination. Ask before the exam is scheduled.
You can claim every condition you have
There is no limit and no penalty. Primary conditions, secondary conditions, and conditions made worse by service all get filed.
You can appeal and be re-evaluated
A denial is not the end. You may submit new evidence, request a higher-level review, appeal to the Board, and ask for re-evaluation when your condition worsens.
You must be considered for TDIU
If your service-connected conditions keep you from holding substantially gainful employment, you may be paid at the 100 percent rate without a 100 percent rating.
Questions Veterans Ask About Radiculopathy (Sciatic, Femoral & Cervical Nerve) Claims
The VA rated my back but not the pain shooting down my leg. Is that wrong?
Almost certainly. Note 1 to the general rating formula for the spine directs the VA to evaluate any associated objective neurologic abnormality separately under an appropriate diagnostic code. If your record shows radiating pain, numbness, weakness, or reflex changes, that separate rating is owed.
Do I get two ratings if both legs are affected?
Yes. Each extremity is rated on its own nerve code, and when both are involved the bilateral factor adds an additional increment to your combined rating.
Why is my radiculopathy only rated mild?
Because the exam probably documented sensory symptoms only. When involvement is wholly sensory, the rating is held to the mild or at most moderate level. Documented muscle weakness, atrophy, and reflex loss are what support moderately severe and severe.

TDIU — Paid at 100% Without a 100% Rating
Total Disability based on Individual Unemployability (38 CFR §4.16) pays you at the 100% rate when your service-connected conditions prevent substantially gainful employment — even if your combined rating is lower. You may qualify if:
- One condition is rated 60% or higher, or
- Two+ conditions combine to 70% with at least one rated 40%, and
- Those conditions keep you from holding steady, gainful work.
- Cannot meet the numbers? Extraschedular TDIU under §4.16(b) may still apply.
Special Monthly Compensation (SMC)
SMC (38 CFR §3.350) pays above the normal schedule for especially serious losses — loss or loss of use of a body part, being housebound, or needing the aid and attendance of another person. Common levels:
- SMC-K — Loss / loss of use — Add-on for loss or loss of use of a specific body part (hand, foot, eye, reproductive organ, or certain other losses). Paid on top of your regular compensation. Can stack (up to the statutory cap).
- SMC-S — Housebound — Statutory housebound: a single 100% disability plus additional disabilities of 60%+, or substantially confined to your home. Veteran-alone rate shown.
- SMC-L — Aid & Attendance — You need the regular aid and attendance of another person, or have anatomical loss/loss of use of both feet, one hand and one foot, blindness, or are permanently bedridden. Veteran-alone rate shown.
- SMC-M — Higher Aid & Attendance — A higher level of aid and attendance (e.g., loss of use of both hands, or loss of use of both legs at a higher level). Veteran-alone rate shown.
These are the benefits veterans most often leave on the table because no one told them they qualified. If any of this sounds like your situation, call an accredited agent at 702-992-4883 — we screen for SMC and TDIU on every case.
