VA Disability: Peripheral Neuropathy

How VA Rates Peripheral Neuropathy

The VA rates peripheral neuropathy based on the severity of nerve damage and functional loss, using Diagnostic Codes 8510 through 8730 — a range that covers every named peripheral nerve in the body. The ICD-10 code for polyneuropathy in disease classified elsewhere is G63, though specific neuropathy types carry their own codes. Your rating depends on which nerve is affected, whether symptoms are mild, moderate, moderately severe, or severe, and whether one or both extremities are involved.

Peripheral neuropathy causes pain, numbness, tingling, weakness, or burning sensations in the hands, feet, legs, or arms. In veterans, it most often results from diabetes (including Agent Orange-linked Type 2 diabetes), burn pit and chemical exposure, Gulf War illness, or direct nerve trauma from injuries sustained in service.

The VA Rating Scale for Peripheral Nerves

VA uses a four-tier severity scale for most peripheral nerve conditions. The percentages shown below apply to each individual nerve affected. Having two separate nerves affected means two separate ratings.

Note that the maximum rating for any single peripheral nerve condition is capped at 80% for complete paralysis. Some specific nerves (such as the sciatic) use slightly different scales — always verify the exact percentages for your specific DC.

Common Diagnostic Codes for Neuropathy

VA assigns neuropathy ratings under the code for the specific nerve affected, not a generic "neuropathy" code. The most common codes veterans encounter are:

• DC 8520 — Paralysis of the sciatic nerve (the most common neuropathy DC for veterans, affecting the entire leg)
• DC 8521 — Paralysis of the external popliteal nerve (peroneal nerve; causes foot drop)
• DC 8522 — Paralysis of the musculocutaneous nerve of the leg (superficial peroneal)
• DC 8515 — Paralysis of the median nerve (hand/wrist; carpal tunnel territory)
• DC 8516 — Paralysis of the ulnar nerve (hand; ring and pinky finger weakness)
• DC 8510 — Paralysis of the musculospiral nerve (radial nerve; wrist drop)
• DC 8626 and DC 8720–8730 range — Small fiber or sensory nerve conditions in the feet

Neuropathy in the Feet: The Most Common Veteran Complaint

Neuropathy in the feet — burning, tingling, or numbness in the soles and toes — is the most frequently claimed neuropathy among veterans. VA typically rates it under DC 8521 (peroneal nerve, external) or DC 8522 (peroneal nerve, superficial) depending on which nerve distribution the symptoms follow. If the entire foot and lower leg are involved, VA may use DC 8520 (sciatic nerve) if the symptoms trace to sciatic nerve compression.

Diabetic Neuropathy: The Agent Orange and PACT Act Chain

Type 2 diabetes is a VA presumptive condition for veterans with qualifying Vietnam-era Agent Orange exposure. Diabetic peripheral neuropathy is a direct complication of Type 2 diabetes, making it service-connectable as a secondary condition through the following chain:

1. Agent Orange exposure (or qualifying PACT Act exposure) → Type 2 diabetes (presumptive service connection)
2. Type 2 diabetes → diabetic peripheral neuropathy (secondary service connection)
3. Each affected nerve receives its own rating under DC 8510–8730

If you have Type 2 diabetes already service-connected, file immediately for neuropathy as a secondary condition. You do not need a separate nexus letter — the medical literature clearly establishes the causal relationship between diabetes and neuropathy. Visit our Burn Pit Exposure page to understand how PACT Act exposures can also trigger the diabetic neuropathy chain for more recent veterans.

Gulf War Illness and Neuropathy

Gulf War illness — a cluster of unexplained symptoms affecting veterans of Southwest Asia service since 1990 — commonly includes peripheral neuropathy as one of its manifestations. VA recognizes Gulf War illness as a presumptive for qualifying veterans, and neuropathy that appears as part of that constellation of symptoms can be service-connected without proving a specific nexus.

Electrodiagnostic Evidence: EMG and Nerve Conduction Studies

The most objective evidence for a neuropathy rating is an electrodiagnostic study. This includes:

• Electromyography (EMG) — measures the electrical activity of muscles to detect nerve damage
• Nerve conduction velocity (NCV) study — measures how fast electrical signals travel along a nerve

A positive EMG/NCV study showing delayed conduction velocity or denervation potentials strongly supports a moderate to moderately severe rating. Request one from your neurologist or physiatrist and include it in your VA claims file. If VA's C&P examiner does not order one, you can obtain a private study and submit it as additional evidence.

Bilateral Neuropathy and the Bilateral Factor

Many veterans have neuropathy in both feet or both hands — bilateral conditions. When both lower extremities or both upper extremities are service-connected, 38 CFR § 4.26 requires VA to apply the bilateral factor: a 10% addition to the combined value of both limb ratings before calculating your overall combined rating. This bonus is automatic and must be applied when you have bilateral service-connected conditions affecting paired extremities.

Key Takeaways

• VA rates peripheral neuropathy under DC 8510–8730 at 10% (mild) through 80% (complete paralysis) per affected nerve.
• Diabetic neuropathy flows directly from service-connected Type 2 diabetes as a secondary condition — no separate nexus letter needed.
• EMG and nerve conduction velocity studies are the strongest objective evidence for neuropathy claims.
• Bilateral neuropathy in paired extremities triggers the 10% bilateral factor bonus under 38 CFR § 4.26.
