Do I need a nexus letter for a Radiculopathy claim?

Not always. The strongest claims rely on service treatment records, presumptive rules, or a clear C&P opinion. A nexus letter is most useful when the condition was diagnosed after service, when STRs are silent, or when the VA issued a negative C&P opinion. See our nexus letter anatomy at /nexus-letters for the seven sections a strong opinion includes.

What is the C&P exam for Radiculopathy actually scoring?

The Disability Benefits Questionnaire (DBQ) for Radiculopathy is the structured form the examiner completes. This page explains the sections of the form and the cited rating criteria in plain English. Describe only facts that are true, including how symptoms vary and affect daily activities or work.

Can I file Radiculopathy as a secondary condition?

Yes, if you can show the condition was caused or aggravated by an already service-connected disability. Common secondary patterns are documented at /nexus-letters. The opinion needs to address the specific theory (direct, secondary, or aggravation) and the medical mechanism.

What if my Radiculopathy claim is denied?

Three appeal lanes open: Higher-Level Review (no new evidence, senior reviewer takes another look), Supplemental Claim (file new evidence, 1-year clock), or Board Appeal (binding decision by a Veterans Law Judge). Pick based on what you have. See /resources/appeals for the full decision tree.

Radiculopathy DBQ Field Guide

The Radiculopathy DBQ rating hinges on one core question: how severe is the nerve involvement? The examiner must assign a severity level — mild, moderate, moderately severe, or severe incomplete paralysis — for the specific nerve group (most often sciatic under DC 8520). Sensory loss alone usually lands lower; motor weakness, atrophy, or reflex changes push the rating higher.

What the examiner is filling out

The Peripheral Nerves DBQ (or Spine DBQ radiculopathy section) asks the examiner to record:

Nerve group and side — sciatic (DC 8520), common peroneal (DC 8521), femoral, etc.
Severity — mild, moderate, moderately severe, severe incomplete paralysis (or complete).
Sensory findings — dermatomal numbness, paresthesia, pain radiation.
Motor findings — weakness, atrophy, reduced reflexes, foot drop.
EMG/NCS results — if available, whether they confirm radiculopathy.

The rating schedule (DC 8520 sciatic nerve)

38 CFR § 4.124a, Diagnostic Code 8520, prints these criteria for paralysis of the sciatic nerve. The words below are the schedule text, checked against eCFR as of October 5, 2026:

80%Complete

Complete; the foot dangles and drops, no active movement possible of muscles below the knee, flexion of knee weakened or (very rarely) lost.

60%Severe

Incomplete: Severe, with marked muscular atrophy.

40%Moderately severe

Incomplete: Moderately severe.

20%Moderate

Incomplete: Moderate.

10%Mild

Incomplete: Mild.

DC 8520 does not define mild, moderate, or moderately severe any further, and it does not mention sensory loss. Foot drop is in the 80% complete-paralysis sentence (“the foot dangles and drops”), not in the 60% sentence. Any description of numbness, weakness, or reflex changes beyond those lines is a paraphrase of how an exam may discuss the findings, not an extra VA criterion. Bilateral radiculopathy triggers the bilateral factor under 38 CFR § 4.26 when each leg is compensable, unless leaving a disability out of the factor produces a higher combined evaluation (§ 4.26(d)).

How to read the criteria

The cited schedule uses severity categories. Review them to understand the form, then describe your actual symptoms and functional effects rather than choosing a category yourself.

Use the criteria to understand the form

The rating schedule describes findings VA may consider. It is not a script. Describe only what is true in your own words, including frequency, duration, treatment, good and bad days, and effects on daily activities or work. Do not select or rehearse a rating tier.

Describe the full picture accurately

Accuracy reminder

Describe what is true in your own words, including frequency, duration, treatment, good and bad days, and effects on daily activities or work. Do not exaggerate, omit improvement, rehearse a rating tier, or guess. If something varies or you do not know, say that clearly.

Bring objective evidence

Relevant records may include examination findings, imaging or electrodiagnostic testing when clinically appropriate, treatment notes, and firsthand lay observations of functional effects.
