Radiculopathy and VA Disability: How Service Connection Works

Nerve pain is the most under-claimed part of a spine file. A veteran files for the back, gets 10 or 20 percent for limited motion, and the burning that runs from the hip to the ankle is treated as part of the back rating. It is not. Under the rating schedule it is a separate disability with its own percentage.

This guide covers what radiculopathy is, how the VA evaluates it, and what has to be in the record before the VA can grant anything.

What radiculopathy actually is

A nerve root leaves the spinal cord through a small opening between two vertebrae. When a disc bulges, a bone spur grows, or the opening narrows, that root gets compressed or irritated. The root carries signals to and from a specific strip of skin and a specific set of muscles, so the symptoms show up along a predictable path rather than in the spine itself.

That is why lumbar radiculopathy is felt in the buttock, thigh, calf, and foot, and why cervical radiculopathy is felt in the shoulder blade, arm, and hand. Our cervical radiculopathy guide covers the neck pattern in detail.

What the VA requires

Direct service connection under 38 CFR 3.303 has three elements, and nerve claims usually turn on the third.

• A current diagnosis - lumbar or cervical radiculopathy, sciatica, peripheral neuropathy, or a named nerve injury
• An in-service event, injury, or exposure - a documented back or neck injury, a fall or vehicle accident, years of load bearing described in your duty history, or an exposure that can damage nerves
• A medical link between the two, explained with reasoning that addresses the alternative causes the VA will weigh

Most radiculopathy is granted on the secondary path rather than the direct one, because the nerve problem grows out of a spine condition that is already service connected. Our radiculopathy secondary to back and neck conditions guide covers that route, and the general secondary service connection guide explains the standard in 38 CFR 3.310.

How the VA rates nerve conditions

38 CFR 4.124a rates peripheral nerves on the degree of paralysis. Complete paralysis of a nerve carries the highest percentage for that nerve. Everything short of that is incomplete paralysis, graded mild, moderate, moderately severe, or severe depending on the nerve.

An important limit sits in the notes to 38 CFR 4.124a: when the involvement is wholly sensory, the rating should be for the mild, or at most the moderate, degree. Numbness and tingling alone generally do not reach the higher levels. Weakness, diminished reflexes, and muscle atrophy are what move a rating up, which is exactly why those findings need to be in the record.

Our nerve VA rating diagnostic codes guide walks the sciatic, femoral, radicular group, median, ulnar, and radial codes line by line.

Neuritis and neuralgia

The schedule separates three related pictures. Paralysis codes in the 8500 series cover loss of function. Neuritis codes in the 8600 series cover nerve inflammation with objective findings such as loss of reflexes, muscle atrophy, sensory disturbances, and constant pain. Neuralgia codes in the 8700 series cover a dull and intermittent pain along the nerve.

Under 38 CFR 4.123, neuritis characterized by loss of reflexes, muscle atrophy, sensory disturbances, and constant pain may be rated up to the maximum for the nerve, but neuritis not characterized by those findings is rated at a maximum equal to moderate incomplete paralysis. Under 38 CFR 4.124, neuralgia is rated at a maximum equal to moderate incomplete paralysis. Those ceilings decide a great many nerve claims.

Separate ratings, not a bigger spine rating

Note (1) to the General Rating Formula for spine disabilities is the sentence to read twice: evaluate any associated objective neurologic abnormalities, including but not limited to bowel or bladder impairment, separately under an appropriate diagnostic code.

In practice that means a service-connected lumbar strain with degenerative disc disease can carry a spine percentage plus a sciatic nerve percentage for the right leg plus another for the left leg. Each one is a separate evaluation, and they combine under the table in 38 CFR 4.25 rather than being added. Our back pain and VA disability and neck and cervical spine guides cover the spine side of the same claim.

Separate does not mean unlimited. 38 CFR 4.14 prohibits pyramiding, rating the same symptom twice under different codes. The nerve rating compensates the neurologic loss; the spine rating compensates the limitation of motion.

Peripheral neuropathy is a different path

Not all nerve damage comes from the spine. Peripheral neuropathy from diabetes, from certain exposures, or from other systemic causes produces a stocking-and-glove pattern of numbness in both feet or both hands rather than a single dermatomal stripe.

Those claims are commonly secondary to service-connected diabetes, and early-onset peripheral neuropathy appears on the herbicide presumptive list in 38 CFR 3.309(e). Our peripheral neuropathy VA rating guide covers both paths.

Where an independent medical opinion fits

The VA decides claims on what is in the file. When a veteran has an imaging study showing nerve root compression, a clinical exam showing sensory loss, and a service history that explains the injury, but no one has written down why the three connect, that gap is the reason for denial.

No honest provider can promise an outcome. A sound opinion states a clear conclusion, explains the medical reasoning, addresses the alternative explanations the VA will weigh such as age, diabetes, or civilian work, and cites the records it relies on. Before spending money on anything, our guide on why VA claims get denied helps identify which element the VA actually found missing, and what a nexus letter is explains what the document does.

Where to go next

Read the diagnostic codes guide for the percentages, the sciatica guide if the pain runs down the leg, the C&P exam guide before your exam is scheduled, and the evidence guide for what belongs in the file. If nerve pain and weakness keep you from working, our TDIU series explains how that is evaluated. Free accredited help with filing is available to every veteran through a Veterans Service Officer.
