Rating Criteria by Level
Under 38 CFR § 4.124a, the VA rates peripheral nerve conditions including radiculopathy on a scale from mild (10%) to severe incomplete paralysis (60%). Each affected extremity is rated separately. The rating reflects current functional impairment of the nerve, not the severity of the underlying spine condition.
Criteria: Minor symptoms such as intermittent paresthesias (numbness, tingling) and mild pain without consistent functional limitation.
The 10% level captures veterans who have occasional radicular symptoms (numbness, tingling, or intermittent shooting pain down the leg or arm) but whose daily function is largely intact. This is the most common outcome for radiculopathy secondary to a service-connected spine condition when symptoms are not constant or disabling.
Most common level for mild intermittent radicular symptoms
Criteria: More frequent pain and paresthesias, some loss of sensation, beginning of muscle weakness or loss of reflex in the affected extremity.
At the 20% level, symptoms occur regularly rather than intermittently. A veteran may notice reduced sensation in part of the foot or hand, slightly diminished reflexes on exam, or mild muscle weakness that begins to interfere with activities. Documented abnormal findings on physical exam (reflex loss, sensory deficit) are important for supporting this level.
Criteria: Persistent pain and paresthesias, moderate loss of sensation, significant muscle weakness (partial paralysis), and loss of reflex throughout the affected extremity.
The 40% level requires objective evidence of significant nerve dysfunction: measurable muscle weakness (typically 3/5 or 4/5 on manual muscle testing), consistent sensory loss across a dermatomal distribution, and absent or markedly reduced deep tendon reflexes. Pain is persistent rather than episodic. EMG and nerve conduction studies often show denervation or slowed conduction at this severity.
Criteria: Near-complete loss of function in the affected extremity, significant muscle atrophy, severe loss of sensation, and major loss of strength.
The 60% level reflects near-complete but not total loss of nerve function. Muscle atrophy is visible on exam, strength is severely reduced (often 2/5 or less in key muscle groups), and sensation is grossly impaired across the distribution of the nerve. For the sciatic nerve specifically, this may include foot drop, inability to bear weight normally, and profound sensory loss in the foot. At this level, the dominant extremity may rate slightly higher than the non-dominant.
Note: At the higher rating levels (40% and 60%), the dominant extremity may rate slightly higher than the non-dominant extremity. If both extremities are affected, each receives its own separate rating under VA math.
How to Service-Connect Radiculopathy
Radiculopathy is one of the most commonly approved secondary conditions in the VA system. Service connection requires a current diagnosis, a service-connected spine condition (or in-service nerve injury), and a medical nexus linking the two. The three most common pathways:
Secondary to Lumbar Spine (Lower Extremity)
Lumbar disc herniation, degenerative disc disease, or spinal stenosis compresses nerve roots causing sciatica and leg radiculopathy. Once the lumbar spine is service-connected, a nexus opinion linking radiculopathy to the same spinal disease is straightforward. Lower extremity radiculopathy secondary to back conditions is among the most commonly approved secondary claims at the VA.
Secondary to Cervical Spine (Upper Extremity)
Cervical disc herniation at C4-C7 compresses nerve roots causing arm and hand radiculopathy. Once the cervical spine is service-connected, upper extremity radiculopathy is a natural secondary claim with a physician's nexus opinion. A cervical spine rating combined with bilateral upper extremity radiculopathy ratings can add substantial combined value.
Direct Service Connection
In cases of acute nerve injury from trauma (blast injury, heavy equipment accident), radiculopathy can be directly service-connected. Documentation of the in-service injury and a current diagnosis are required. Direct service connection applies when the nerve itself was injured during service rather than being compressed by a degenerative spine condition.
What Happens at Your C&P Exam
The VA will schedule a compensation and pension exam for radiculopathy. The examiner will assess objective signs of nerve dysfunction as well as your reported symptoms. For radiculopathy, the examiner will typically perform or review:
- Straight leg raise test (for lumbar/sciatic radiculopathy)
- Nerve tension signs and dermatomal sensory testing
- Motor strength testing in affected extremity (scale 0-5)
- Deep tendon reflex testing (patellar, Achilles for lower; biceps, triceps for upper)
- Electromyography (EMG) and nerve conduction velocity (NCV) findings if available
- Assessment of pain pattern: dermatomal distribution consistent with claimed nerve root
Bring imaging (MRI showing disc herniation or foraminal stenosis at the relevant level), any EMG or nerve conduction study results, and your private nexus opinion if you have one. Be specific about which extremity is affected and describe the full distribution of symptoms.
Related Conditions to Claim Alongside Radiculopathy
Once radiculopathy is service-connected, you can file secondary claims for conditions it caused or worsened, or claim the underlying spine condition that causes the radiculopathy. Each adds its own rating to your combined total.
Back PainLumbar radiculopathy is almost always secondary to service-connected lumbar spine disease. Claim both together for maximum combined rating.
Neck Pain (Cervical Spine)Cervical radiculopathy secondary to service-connected cervical strain adds a separate peripheral nerve rating to your combined total.
Depression / AnxietyChronic neuropathic pain causes depression and anxiety. Secondary mental health claims are well-supported with a physician nexus opinion.
Sleep DisordersRadicular pain disrupts sleep, particularly when lying down. Secondary sleep disorder claims are supported by a nexus opinion linking pain to sleep disruption.
Foot Drop / Gait DisturbanceSevere peroneal nerve involvement from lumbar radiculopathy can cause foot drop. Rated separately under DC 8521 and may require adaptive equipment.

Radiculopathy VA Rating FAQ
What is the difference between radiculopathy and the underlying spine condition?
The spine condition (lumbar strain, cervical disc disease) is rated on range of motion under 38 CFR § 4.71a. Radiculopathy is the nerve damage that results from the spine condition and is rated separately under 38 CFR § 4.124a based on how severely the nerve is affected. Both ratings combine under VA math, so claiming both is essential.
Can I get a separate rating for radiculopathy in both legs?
Yes. If lumbar spine disease causes radiculopathy in both lower extremities, each leg receives its own separate rating. Bilateral lower extremity radiculopathy from a service-connected lumbar condition commonly results in two 10% ratings (one per leg), adding significant value to the combined total under VA math.
Does radiculopathy have to be proven by an EMG?
No. Clinical evidence alone (positive straight leg raise, absent reflex, sensory loss in a dermatomal pattern, documented pain) is sufficient to support a radiculopathy diagnosis. EMG and nerve conduction studies strengthen the claim but are not required.
How is sciatic nerve radiculopathy rated differently?
The sciatic nerve (DC 8520) is rated at mild (10%), moderate (20%), moderately severe (40%), or severe (60%) incomplete paralysis levels. The sciatic nerve is the largest nerve in the body and controls much of the leg. Severe sciatic involvement with significant weakness, atrophy, and sensory loss can reach 60% on that extremity alone.
Can radiculopathy be service connected if the spine condition is not?
Generally no. Radiculopathy requires an underlying cause (disc herniation, stenosis) that must itself be service-connected for secondary service connection to apply. However, in cases of direct nerve trauma during service (injury to the arm, blast injury compressing the sciatic nerve), direct service connection without a spine condition is possible.
What is a nexus letter and do I need one for radiculopathy?
A nexus letter is a physician's written opinion linking your radiculopathy to your service-connected spine condition. The letter should state that it is "at least as likely as not" that the radiculopathy is caused by or secondary to the service-connected lumbar or cervical spine disease. A nexus letter significantly increases approval rates for secondary claims.
Will treating radiculopathy (surgery or injections) reduce my VA rating?
It could, if symptoms genuinely and sustainably improve after treatment. The VA rates current functional impairment. If a discectomy eliminates radicular symptoms, the rating could be reduced at the next exam. However, many veterans have residual symptoms even after surgery, and those residuals are still ratable. Do not forego needed treatment to preserve a rating.
