The VA rates back (spine) conditions under the General Rating Formula for the Spine, primarily by your measured range of motion and any abnormal posture or muscle spasm — commonly 10%, 20%, 40%, or higher for the most severe cases. A service-connected back condition is a frequent gateway to secondary claims, especially radiculopathy (sciatica) down the legs, and depression from chronic pain.
Diagnostic code
General Rating Formula for the Spine (DC 5235–5243)
How the rating works
Ratings rise as forward flexion of the spine decreases (or with favorable/unfavorable ankylosis in severe cases): roughly 10% for mild loss of motion, 20% for moderate limitation, 40% for forward flexion of 30 degrees or less, and higher for ankylosis. Painful motion and flare-ups must be accounted for in the exam.
Secondary conditions to watch for
These are commonly connected to back pain — each can be rated on top of it with a medical nexus. Most veterans leave these on the table.
Radiculopathy (sciatica)
Nerve pain into the legs, rated separately for each limb.
Depression
Chronic pain is a recognized cause of secondary depression.
Secondary hip/knee/ankle strain
An altered gait from back pain can overload other joints.
Evidence that wins this claim
- Imaging or exam confirming the spine diagnosis.
- A range-of-motion (goniometer) measurement, ideally noting flare-ups.
- Documentation of radiating symptoms for radiculopathy secondaries.
- Statements on how the back limits work and daily activity.
Back pain — frequently asked questions
- How does the VA rate back conditions?
- Under the General Rating Formula for the Spine, mainly by measured range of motion (forward flexion) plus posture and muscle spasm — commonly 10%, 20%, or 40%, with higher ratings for ankylosis.
- What conditions are secondary to a back injury?
- Radiculopathy (sciatica) into the legs is the most common, along with depression from chronic pain and strain on the hips, knees, or ankles from an altered gait.
