Radiculopathy Secondary to a Back Condition

Why radiculopathy is a separate rating

Note (1) to the General Rating Formula for Diseases and Injuries of the Spine in 38 CFR § 4.71a expressly instructs raters to 'evaluate any associated objective neurologic abnormalities, including, but not limited to, bowel or bladder impairment, separately, under an appropriate diagnostic code.' Radiculopathy is the most common such abnormality and is rated separately under the peripheral-nerve diagnostic codes in § 4.124a.

This means a single spine condition can produce three or more ratings: the schedular spine rating, plus a left-extremity radiculopathy rating, plus a right-extremity radiculopathy rating, plus separate ratings for any bladder or bowel involvement.

Evidence VA looks for

• Existing service connection for the underlying lumbar or cervical spine condition.
• Neurologic exam findings — diminished or absent reflexes, dermatomal sensory loss, motor weakness, positive straight-leg raise (for lumbar).
• EMG/nerve conduction study identifying the affected nerve root(s) and severity (mild, moderate, severe, complete paralysis).
• MRI showing the structural cause — herniated disc, foraminal stenosis, spondylolisthesis — consistent with the symptom distribution.
• Treatment records documenting persistence of symptoms over time.

Rating mechanics — lower extremity (sciatic nerve, DC 8520)

• 10% — mild incomplete paralysis.
• 20% — moderate incomplete paralysis.
• 40% — moderately severe incomplete paralysis.
• 60% — severe incomplete paralysis with marked muscular atrophy.
• 80% — complete paralysis (foot dangles and drops, no active movement possible of muscles below the knee, flexion of knee weakened or lost).

Rating mechanics — upper extremity (median, ulnar, radial nerves)

Cervical radiculopathy is rated under whichever nerve corresponds to the affected level: median nerve (DC 8515) for C6/C7 pattern, ulnar (DC 8516) for C8/T1, radial (DC 8514) for C5/C6 motor patterns. Each has dominant-vs-non-dominant hand modifiers — dominant-hand ratings are typically higher at each severity level.

Bilateral factor

When both lower (or both upper) extremities have ratable disabilities, the bilateral factor under 38 CFR § 4.26 adds 10% of the combined value before applying the combined ratings table. This often produces a meaningful bump that raters miss when entering each side separately.

Common pitfalls

Radiculopathy can be missed entirely when the C&P examiner does not perform a dedicated neurologic exam or when EMG is not in the file. The Note (1) instruction is mandatory — a documented neurologic abnormality must be separately rated, not absorbed into the spine rating.

Severity grading is also a frequent issue: examiners default to 'mild' when the symptom picture (persistent numbness, weakness, reflex loss) actually supports 'moderate' (20% per side instead of 10%).

Where these claims break down

• ×Filing without an EMG or detailed neurologic exam when symptoms are clearly present.
• ×Allowing the rater to absorb radiculopathy into the spine rating instead of granting a separate rating per side.
• ×Missing the bilateral factor under § 4.26 when both legs (or both arms) are affected.
• ×Accepting a 'mild' rating without documenting reflex loss, weakness, or sensory deficit that supports 'moderate' or higher.
