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 — most common)
The tier percentages and severity descriptors below are taken directly from 38 CFR § 4.124a, Diagnostic Code 8520. They are the exact language the rater uses.
Service-connected diagnosis exists but no ratable impairment.
Subjective sensory symptoms (pain, numbness) with minimal or no objective findings.
Sensory loss plus some motor weakness or reflex changes that affect function.
Clear motor involvement, atrophy, or significant weakness in the affected distribution.
Marked motor loss, atrophy, foot drop, or near-complete loss of function short of total paralysis.
Phrases that map to each tier
These are example phrases — not regulatory language. They are veteran-friendly translations of the symptoms that satisfy each tier above.
Magic words for this tier
To establish moderate or higher:
- “I have constant radiating pain down my leg into my foot with numbness in the same pattern.”
- “My left foot drops when I walk and I have to lift my knee higher.”
- “I have measurable weakness on dorsiflexion and reduced ankle jerk.”
Magic words for this tier
To establish moderately severe or severe:
- “I have visible atrophy in the calf and cannot stand on my toes or heel on that side.”
- “The weakness is so bad I use a brace or cane and still stumble.”
- “EMG confirmed active denervation in the L5-S1 distribution.”
What NOT to say
What NOT to say
- “The pain comes and goes.” (Vague — tie it to a dermatome and frequency.)
- “My back hurts and sometimes my leg tingles.” (Fails to separate radiculopathy from back pain.)
- “I can still walk okay.” (Undercuts motor findings needed for 40%+.)
- “It’s just sciatica.” (Use the word radiculopathy and describe objective deficits.)
Bring objective evidence
The strongest claims pair a current EMG or MRI showing nerve root compression with a treating provider note that explicitly states the severity level (moderate, moderately severe, etc.). Lay statements from family describing foot drop or frequent stumbling also help.
