Peripheral Neuropathy VA Rating: Arm and Leg Nerve Criteria (38 CFR 4.124a)

General rating rules: Incomplete paralysis, neuritis, neuralgia, and the wholly sensory ceiling

Four binding rules in 38 CFR 4.120, 38 CFR 4.123, 38 CFR 4.124, and the introductory notes in 38 CFR 4.124a govern peripheral nerve evaluations:

1. Incomplete paralysis (38 CFR 4.124a): Total immobilization is not required under 8500-series paralysis codes. The introductory note in 38 CFR 4.124a defines incomplete paralysis as “a degree of lost or impaired function substantially less than the type picture for complete paralysis given with each nerve, whether due to varied level of the nerve lesion or to partial regeneration.” Incomplete paralysis is graded as mild, moderate, moderately severe (DC 8520), or severe based on relative motor, trophic, and sensory impairment under 38 CFR 4.120.
2. Wholly sensory involvement ceiling (38 CFR 4.124a): The introductory note in 38 CFR 4.124a states: “When the involvement is wholly sensory, the rating should be for the mild, or at most, the moderate degree.” If your neuropathy causes numbness, tingling, or pain, but examination shows normal 5/5 strength, intact reflexes, no atrophy, and no trophic changes, your rating cannot exceed mild or moderate.
3. Neuritis ceilings (DC 8610–8630 under 38 CFR 4.123): Peripheral neuritis “characterized by loss of reflexes, muscle atrophy, sensory disturbances, and constant pain, at times excruciating” is rated up to severe incomplete paralysis. Without those organic changes, neuritis is capped at moderate—or, for the sciatic nerve (DC 8620), moderately severe (40%) incomplete paralysis.
4. Neuralgia ceilings (DC 8710–8730 under 38 CFR 4.124): Peripheral neuralgia, characterized usually by dull and intermittent pain of typical nerve distribution, is capped at moderate incomplete paralysis.

Lower extremity peripheral neuropathy rating table (38 CFR 4.124a, DC 8520–8530)

Under 38 CFR 4.124a, lower extremity nerve ratings apply identical percentages to the right and left legs. For stocking-distribution polyneuropathy in the feet and lower legs, the VA most commonly evaluates each leg under Diagnostic Code 8520 (Sciatic nerve) or Diagnostic Code 8521 (External popliteal / common peroneal nerve), and evaluates anterior thigh involvement under Diagnostic Code 8526 (Anterior crural / femoral nerve).

Under the veteran-alone schedule effective 2025-12-01, 10% pays $180.42 monthly, 20% pays $356.66, 30% pays $552.47, 40% pays $795.84, 60% pays $1,435.02, and 80% pays $2,102.15. For spinal nerve compression, see our sciatica VA rating and radiculopathy VA rating guides.

Upper extremity peripheral neuropathy rating table (38 CFR 4.124a, DC 8510–8519)

Upper extremity nerve ratings under Diagnostic Codes 8510–8519 in 38 CFR 4.124a depend on whether the limb is Major (dominant) or Minor (non-dominant). Under 38 CFR 4.69, only one hand is considered dominant, and for an ambidextrous veteran, the injured or most severely injured hand is rated as dominant.

The Note following DC 8519 in 38 CFR 4.124a states: “Combined nerve injuries should be rated by reference to the major involvement, or if sufficient in extent, consider radicular group ratings.” When systemic neuropathy affects multiple nerves in one arm, adjudicators generally assign one rating per upper extremity under the predominantly affected nerve (DC 8514, 8515, or 8516) or a radicular group code (DC 8510–8513).

Service connection: Agent Orange, diabetes mellitus, and secondary claims

1. Presumptive early-onset peripheral neuropathy from Agent Orange (38 U.S.C. 1116, 38 CFR 3.309(e), and 3.307(a)(6)): Under 38 CFR 3.309(e), early-onset peripheral neuropathy is a presumptive herbicide condition. Qualifying herbicide exposure covers service in the Republic of Vietnam, the Korean DMZ, or C-123 aircraft operations under 38 CFR 3.307(a)(6), as well as the expanded Korean DMZ period (September 1, 1967, to August 31, 1971) and PACT Act locations (Thailand bases, Laos, Cambodia, Guam, American Samoa, and Johnston Atoll) established under 38 U.S.C. 1116 and listed on the VA Agent Orange eligibility page. Under 38 CFR 3.307(a)(6)(ii), standalone presumptive service connection requires manifestation to 10% or more within one year after the last date of in-service herbicide exposure.
2. Diabetic peripheral neuropathy secondary to Type 2 diabetes (38 CFR 3.310 and 4.119, DC 7913): Under 38 CFR 3.309(e) and 3.307(a)(6)(ii), Type 2 diabetes mellitus has no 1-year deadline and can be presumptively connected at any time after herbicide exposure. Under 38 CFR 4.119, DC 7913 Note (1) directs the VA to “evaluate compensable complications of diabetes separately unless they are part of the criteria used to support a 100-percent evaluation.” Veterans with service-connected diabetes receive separate secondary ratings under 38 CFR 3.310 for each extremity affected by diabetic neuropathy.
3. Direct, chronic, and secondary pathways (38 CFR 3.303, 3.309(a), and 3.310): Neuropathy may also be connected directly from in-service nerve trauma, cold injury, or solvent exposure; presumptively within 1 year of discharge as an organic nervous system disease under 38 CFR 3.309(a); or secondarily to chemotherapy, renal failure, hypothyroidism, or B12 deficiency. Conversely, service-connected neuropathy may support secondary claims under 38 CFR 3.310 for orthopedic injuries from falls or altered gait, trophic ulcers, or secondary depression and anxiety (38 CFR 4.130).

How the C&P exam and VA DBQs measure peripheral neuropathy

At a C&P exam, the clinician completes either the Diabetic Sensory-Motor Peripheral Neuropathy DBQ or the Peripheral Nerves Conditions (Not Including Diabetic Sensory-Motor Peripheral Neuropathy) DBQ from VA.gov’s Public DBQ portal:

• Symptoms and strength (Sections 3–4A / III–IV-A): Grades constant pain, intermittent pain, paresthesias/dysesthesias, and numbness across all four limbs, and tests muscle strength from 0/5 to 5/5 (elbow, wrist, grip, and pinch in the arms; knee and ankle flexion/extension in the legs). A score of 4/5 or lower is evidence of motor involvement beyond the wholly sensory ceiling (wholly sensory involvement is rated mild or, at most, moderate).
• Reflexes, sensation, atrophy, and trophic changes (Sections 4B–4H / IV-B–VII): Grades biceps, triceps, brachioradialis, knee, and ankle reflexes (0 absent to 4+), light-touch/monofilament sensation, index-finger and great-toe position sense, tuning-fork vibration and cold sensation, muscle atrophy (circumference in centimeters), and trophic changes (loss of hair, smooth shiny skin).
• Nerve grading and EMG rules (Sections 5–9 / X–XV): The Diabetic Neuropathy DBQ grades upper limbs under the radial (DC 8514), median (DC 8515), or ulnar (DC 8516) nerves and lower limbs under the sciatic (DC 8520) and/or femoral (DC 8526) nerves. Both DBQs record assistive devices, evaluate whether loss of function equals amputation with prosthesis (for Special Monthly Compensation under 38 CFR 3.350(a)), and note that electromyography (EMG) studies are rarely required when clinical findings in a stocking-and-glove distribution confirm the diagnosis.

Combining ratings and the bilateral factor (38 CFR 4.25 and 4.26)

Under 38 CFR 4.26, when peripheral neuropathy affects paired limbs, the VA combines the extremity ratings under 38 CFR 4.25 and adds 10% of that combined value:

• Both legs affected: Two 20% sciatic ratings (DC 8520) combine to 36%, plus 3.6 bilateral factor = 39.6%, rounding up to 40% ($795.84 monthly alone).
• All four extremities affected (38 CFR 4.26(b)): Under 38 CFR 4.26(b), when compensable neuropathy affects both upper and both lower extremities, the VA combines all four extremity ratings in order of severity and adds 10% of that combined value before combining with non-extremity ratings (subject to the favorable-calculation exception in 38 CFR 4.26(d)). For example, 20% right leg, 20% left leg, 10% right hand, and 10% left hand combine to 48%, plus 4.8 bilateral factor = 52.8% (53%), combining with a 20% diabetes rating to reach 62.4% (60% combined, paying $1,435.02 monthly alone).

When to get accredited help with your claim

If your peripheral neuropathy claim was denied or underrated under the wholly sensory rule, accredited Veterans Service Organizations (VSOs)—such as the DAV, VFW, and American Legion—provide free representation, while VA-accredited claims agents and attorneys handle appeals. No representative can guarantee an outcome; verify credentials in the VA Office of the General Counsel Accreditation Search.
