Nerve damage is one of the most common, and most underrated, service-connected disabilities affecting veterans. Two of the conditions that appear most frequently in VA disability claims are peripheral neuropathy and radiculopathy. Both involve damage to the nervous system, both can be debilitating, and both are often more difficult to get rated at a fair level than they should be.
If you’re a veteran experiencing pain, numbness, tingling, or weakness in your limbs, this guide breaks down what these two conditions are, how the VA rates them, and what you can do to maximize your compensation.
What Is Peripheral Neuropathy?
Peripheral neuropathy refers to damage or dysfunction of the peripheral nerves, the vast network of nerves that carry signals between your brain and spinal cord and the rest of your body. When these nerves are damaged, the communication breaks down, causing a range of symptoms that affect sensation, movement, and organ function.
Common Symptoms
- Burning, tingling, or electric-shock sensations, especially in the hands and feet
- Numbness or loss of feeling in the extremities
- Muscle weakness or loss of coordination
- Sharp, jabbing, or throbbing pain
- Sensitivity to touch, even light contact with clothing
- Inability to feel heat, cold, or pain normally
How Veterans Develop Peripheral Neuropathy
Peripheral neuropathy can develop from several service-related causes:
- Agent Orange exposure: the VA recognizes early-onset peripheral neuropathy as a presumptive condition for Vietnam-era veterans exposed to herbicides.
- Type 2 diabetes: a presumptive condition linked to Agent Orange exposure, and diabetic neuropathy is one of its most common complications.
- Toxic chemical or heavy metal exposure during service.
- Physical trauma: repetitive impact or compression injuries sustained in training or combat.
- PACT Act burn pit exposure: expanding eligibility for post-9/11 veterans.
How the VA Rates Peripheral Neuropathy
The VA rates peripheral neuropathy under Diagnostic Code 8520 (sciatic nerve) or related nerve codes depending on which nerves are affected. Ratings are applied per nerve, and per limb meaning a veteran with neuropathy affecting both legs and both arms may receive multiple separate ratings that combine under the VA’s “combined ratings” formula.
Disability ratings for peripheral neuropathy typically range from 10% to 80%, based on the severity of functional impairment:
- 10%: Mild incomplete paralysis (intermittent numbness or tingling)
- 20%: Moderate incomplete paralysis
- 40%–60%: Severe incomplete paralysis (significant motor or sensory loss)
- 80%: Complete paralysis
Many veterans are initially rated too low because VA examiners don’t fully document the functional impact on daily life. Thorough medical evidence and nexus letters are critical to getting the right rating.
What Is Radiculopathy?
Radiculopathy is nerve pain that originates in the spine. It occurs when a nerve root, where the nerve exits the spinal column, becomes compressed, inflamed, or damaged. Unlike peripheral neuropathy, which affects nerves throughout the body, radiculopathy has a specific spinal origin and typically radiates pain along a defined nerve pathway.
The most common forms veterans experience are lumbar radiculopathy (lower back, affecting the legs and feet, commonly called sciatica) and cervical radiculopathy (neck, affecting the arms and hands).
Common Symptoms
- Sharp, shooting pain that travels from the back or neck down into the arms or legs
- Numbness or tingling along the nerve’s pathway (e.g., down the back of the leg to the foot)
- Muscle weakness in the affected limb
- Reflexes that are diminished or absent
- Pain that worsens with movement, sitting, or standing for extended periods
How Veterans Develop Radiculopathy
Military service places enormous strain on the spine. Radiculopathy in veterans is commonly caused by:
- Heavy load-bearing (rucksacks, body armor, equipment) that compresses spinal discs over years of service.
- Traumatic injuries from combat, vehicle accidents, or parachute landings causing herniated or bulging discs.
- Repetitive physical labor, including lifting, operating heavy machinery, and prolonged vibration exposure.
- Degenerative disc disease that progresses after service — which can still be service-connected if the underlying condition began during active duty.
How the VA Rates Radiculopathy
Radiculopathy is rated separately from the underlying back condition that causes it. This is a critical point many veterans miss: you can — and should — receive a VA rating for your back injury and a separate rating for the radiculopathy it causes.
Radiculopathy is rated under the specific peripheral nerve affected. For example, lumbar radiculopathy causing sciatica is rated under Diagnostic Code 8520 for the sciatic nerve. Ratings follow the same scale as neuropathy, 10% to 80%, based on severity of incomplete or complete paralysis of the affected nerve.
Because radiculopathy is rated on a nerve-by-nerve basis, a veteran with both lumbar and cervical radiculopathy affecting multiple limbs can accumulate significant combined disability percentages.
How Peripheral Neuropathy and Radiculopathy Can Work Together in Your Claim
These two conditions often co-exist in veterans and understanding their interaction is important for building a strong claim. A veteran might have lumbar radiculopathy (from a service-connected back condition) that has, over time, contributed to peripheral nerve damage. Or a veteran with diabetes-related peripheral neuropathy may also have cervical radiculopathy from a neck injury.
In both cases, the conditions can be claimed as:
- Direct service connection: if the nerve condition itself began during service.
- Secondary service connection: if the nerve condition developed as a result of another service-connected condition (e.g., diabetic neuropathy secondary to service-connected Type 2 diabetes).
- Presumptive service connection: for veterans exposed to Agent Orange or toxic burn pits under the PACT Act.
Tips for Strengthening Your Claim
- Get a thorough neurological evaluation. EMG/nerve conduction studies provide objective evidence the VA takes seriously.
- Document functional impairment. How does the condition affect your ability to walk, grip, work, or sleep? This directly impacts your rating.
- Obtain a nexus letter. A physician who connects your nerve condition to your military service significantly strengthens your claim.
- Claim each affected nerve separately. Otherwise, the VA may bundle multiple nerve conditions into a single low rating.
- Appeal an underrated decision. If your rating doesn’t reflect the severity of your symptoms, you have the right to appeal.
