VA Disability: Back Pain (General Spine Formula)

Reviewed by Jonathan Teplitsky · Updated July 2026

How does the VA rate back pain?

General, unspecified back pain is rated under 38 CFR Part 4, § 4.71a — the General Rating Formula for the Spine. This is the same regulation the VA uses for every spine condition, from a simple strain to a fused vertebra. Ratings run from 10% to 100%, and the number you get depends almost entirely on how far your spine moves, not on how much pain you report.

One important distinction first: “back pain” describes a symptom, not a diagnosis. Before the VA can rate anything, your medical record needs a diagnosed condition — lumbar strain, degenerative disc disease, a bulging or herniated disc, arthritis of the spine, or similar. Once you have that diagnosis, the rating table below is what applies.

Ankylosis means the spine is fixed in place and cannot move — “favorable” means it is fused in a mostly upright position; “unfavorable” means it is fused in a flexed, extended, or otherwise poor position. The 50% and 100% levels are reserved for these cases and are far less common than the 10–40% range.

Muscle spasm and guarding can matter as much as motion

Range of motion is not the only path to a rating. If your back condition causes muscle spasm or guarding severe enough to change how you walk (abnormal gait) or how your spine curves (abnormal spinal contour), that alone supports at least a 20% rating — even if your measured flexion is better than the 20% motion threshold. Make sure your examiner notes gait changes and visible spasm, not just a motion number.

What diagnosis is behind your back pain?

Because “back pain” is a symptom, the VA rates the underlying diagnosis using this same formula. The site has dedicated pages with diagnosis-specific evidence and secondary-condition guidance for the most common causes:

• Lumbar spine strain — a soft-tissue muscle or ligament injury, the most common cause of chronic lower-back pain claims.
• Bulging or herniated disc — rated under this same formula and, separately, under the Intervertebral Disc Syndrome (IVDS) bed-rest formula, whichever is higher.
• Degenerative disc disease — gradual, age-related disc wear, evaluated the same way but documented differently from an acute injury.

If your diagnosis is not one of these, this page's General Spine Formula chart still applies — the rating mechanics are the same across every spine diagnosis.

Radiculopathy: the add-on many veterans miss

Radiculopathy — nerve pain that radiates from the spine down into a leg or arm — is rated separately under its own diagnostic code (commonly DC 8520 for the sciatic nerve) and then added to your spine rating. It is not folded into the spine percentage above. If you have numbness, tingling, weakness, or shooting pain down a limb in addition to back pain, ask your examiner to document it specifically so it can be rated on its own.

Evidence that supports a back pain claim

• Goniometer range-of-motion readings from a C&P exam or your own treating physician.
• Imaging — an X-ray or MRI showing the underlying diagnosis (arthritis, disc disease, stenosis, etc.).
• A firm diagnosis in your medical record, not just a symptom note of “back pain.”
• A nexus letter if the condition is claimed as secondary to another service-connected disability, such as a knee or hip condition that altered your gait over time.

At the C&P exam, describe how the pain limits specific movements — bending, lifting, sitting for long periods — rather than only its intensity. The examiner's motion measurements, not your pain description alone, drive the percentage.

Estimate your combined rating

Back conditions are rarely rated alone — many veterans also carry a separate radiculopathy rating, or other conditions entirely. Use our VA disability rating calculator to see how a spine rating combines with your other conditions under VA math.
