Understanding spine vs. nerve symptoms
Back conditions are often evaluated based on spine motion, ankylosis, or other mechanical spine criteria under the General Rating Formula for Diseases and Injuries of the Spine. Radiculopathy, on the other hand, involves nerve symptoms such as radiating pain, numbness, tingling, weakness, reflex changes, or sensory changes in an extremity.
When separate ratings may apply
Separate ratings may be possible when the nerve symptoms are distinct from the spine limitation itself. Evidence should document the side, nerve distribution, symptoms, clinical findings, and functional impact. The exact nerve code depends on the specific nerve involved.
Avoidance of pyramiding
Separate ratings are not automatic. Under 38 CFR 4.14, VA must avoid pyramiding, meaning the same symptom or limitation should not be compensated twice. The evidence must show distinct functional impairment.
