Peripheral neuropathy is a condition that affects the nerves outside the brain and spinal cord, causing symptoms such as numbness, tingling, burning pain, weakness, and loss of coordination in the hands, arms, feet, and legs. For veterans, peripheral neuropathy is frequently secondary to other service-connected conditions, most commonly Type 2 diabetes and spinal conditions causing radiculopathy. Because the VA rates each affected extremity separately, a veteran with neuropathy in multiple limbs can accumulate significant combined disability ratings.
The VA rates peripheral neuropathy under the diagnostic codes for diseases of the peripheral nerves, found at 38 CFR 4.124a. The specific diagnostic code depends on which nerve is affected. For the upper extremities, the most commonly applied codes are DC 8515 for the median nerve, DC 8516 for the ulnar nerve, and DC 8510 for the upper radicular group. For the lower extremities, DC 8520 for the sciatic nerve and DC 8521 for the external popliteal (common peroneal) nerve are the most frequently used. Each code has its own rating schedule, and the ratings differ based on whether the condition involves incomplete paralysis (at various severity levels) or complete paralysis.
For the sciatic nerve (DC 8520), which is the most commonly rated nerve in lower extremity neuropathy, the ratings are: 10% for mild incomplete paralysis, 20% for moderate incomplete paralysis, 40% for moderately severe incomplete paralysis, 60% for severe incomplete paralysis with marked muscular atrophy, and 80% for complete paralysis where the foot dangles and drops, there is no active movement possible of the muscles below the knee, and flexion of the knee is weakened or lost. The sciatic nerve controls most of the sensation and movement in the leg below the knee, so impairment of this nerve can be profoundly disabling.
For the median nerve (DC 8515), ratings for the dominant (major) hand are: 10% for mild incomplete paralysis, 30% for moderate, 50% for severe, and 70% for complete paralysis. For the non-dominant (minor) hand: 10% for mild, 20% for moderate, 40% for severe, and 60% for complete paralysis. The median nerve controls sensation in much of the palm and fingers and motor function for several hand muscles, making its impairment particularly relevant to occupational functioning.
The severity levels of incomplete paralysis are assessed based on a combination of subjective symptoms and objective findings. Mild incomplete paralysis typically involves sensory symptoms such as numbness, tingling, or mild burning pain without significant motor impairment. Moderate incomplete paralysis involves more pronounced sensory symptoms plus some measurable loss of reflexes, sensation, or motor strength. Moderately severe incomplete paralysis involves significant sensory and motor impairment that noticeably affects function. Severe incomplete paralysis involves substantial loss of nerve function approaching complete paralysis.
The C&P exam for peripheral neuropathy includes both subjective assessment and objective neurological testing. The examiner will perform sensory testing using monofilament, tuning fork, or pinprick to assess sensation in the affected areas. They will test reflexes, particularly deep tendon reflexes at the ankle and knee. They will assess muscle strength in the affected extremities. They will look for signs of muscle atrophy. They will review nerve conduction studies and electromyography (EMG) results if available. These objective findings, combined with your description of symptoms, determine the severity level assigned.
Nerve conduction studies and EMG testing are particularly valuable evidence for peripheral neuropathy claims. These tests objectively measure the electrical activity in nerves and muscles, providing concrete data about the degree of nerve damage. If you have not had these tests performed, requesting them from your physician or neurologist before filing your claim can significantly strengthen your evidence file. The results of these tests give the C&P examiner objective data to support a severity determination.
Diabetic peripheral neuropathy is the most common secondary pathway for these claims. Type 2 diabetes damages peripheral nerves through prolonged exposure to elevated blood sugar levels, a process called diabetic neuropopathy. The damage typically begins in the longest nerves first, which is why symptoms usually appear in the feet and legs before the hands and arms. If you have service-connected Type 2 diabetes and have developed numbness, tingling, burning, or weakness in your extremities, you should file a secondary claim for peripheral neuropathy in each affected extremity.
Radiculopathy secondary to spinal conditions is the other major pathway. When a herniated disc, bone spur, or spinal stenosis compresses a nerve root in the lumbar or cervical spine, it can cause radicular symptoms that travel down the affected arm or leg. Lumbar radiculopathy typically follows the sciatic nerve distribution, causing symptoms in the buttock, thigh, calf, and foot. Cervical radiculopathy can affect the shoulder, arm, and hand. If you have a service-connected spinal condition and experience radiating symptoms into your extremities, peripheral neuropathy or radiculopathy should be claimed as a secondary condition.
The bilateral factor is particularly relevant for peripheral neuropathy claims because the condition frequently affects both sides of the body, especially in diabetic neuropathy. Under 38 CFR 4.26, when disabilities affect both paired extremities, the VA applies a bilateral factor that slightly increases the combined value of those bilateral ratings. For a veteran with neuropathy in both legs and both arms, the bilateral factor is applied twice: once for the bilateral lower extremities and once for the bilateral upper extremities.
When preparing your claim, document how peripheral neuropathy affects your daily activities. If you drop objects because of hand numbness, describe that. If you have difficulty walking because of foot numbness or weakness, explain the specific limitations. If you have fallen because of lost sensation or coordination, document those incidents. If the neuropathy affects your sleep, note that as well. Functional impact evidence is what elevates a neuropathy claim from a lower to a higher severity level.
The Claim Recon Rating Calculator is invaluable for neuropathy claims because it helps you understand how multiple extremity ratings combine with your primary condition and other disabilities. The C&P Exam Simulator prepares you for the neurological examination and the specific sensory and motor tests the examiner will perform. The Health Logger lets you track neuropathy symptoms, including numbness episodes, pain levels, and functional limitations, over time. Ask Intel AI can help you navigate the complex web of peripheral nerve diagnostic codes and determine which codes apply to your specific symptoms. The Secondary Condition Finder maps the established secondary pathways from diabetes and spinal conditions to peripheral neuropathy.
