Back ratings come down to degrees on a protractor. Not how much it hurts, not how many pills you take — how far forward you can bend before the examiner writes down a number.
That sounds harsh, and it is. But it also means the rules are knowable, and two of them are worth more than most veterans realize.
Pain Is Already Priced In
The General Rating Formula for Diseases and Injuries of the Spine applies “with or without symptoms such as pain (whether or not it radiates), stiffness, or aching.”
That single clause explains a lot of frustration. Pain doesn’t add to the rating — the formula assumes it. What moves the number is measured limitation.
Which is why describing severe pain at an exam, without demonstrating what it does to your motion, often produces a rating that feels far too low.
The Thoracolumbar Ladder
| Rating | Lower back (thoracolumbar) criteria |
|---|---|
| 100% | Unfavorable ankylosis of the entire spine |
| 50% | Unfavorable ankylosis of the entire thoracolumbar spine |
| 40% | Forward flexion 30 degrees or less, or favorable ankylosis of the entire thoracolumbar spine |
| 20% | Forward flexion greater than 30 but not greater than 60 degrees; or combined range of motion not greater than 120 degrees; or muscle spasm or guarding severe enough to cause abnormal gait or abnormal spinal contour |
| 10% | Forward flexion greater than 60 but not greater than 85 degrees; or combined range of motion greater than 120 but not greater than 235 degrees; or muscle spasm, guarding, or localized tenderness not causing abnormal gait or contour; or vertebral body fracture with loss of 50% or more of height |
Normal forward flexion of the thoracolumbar spine is 0 to 90 degrees, and normal combined range of motion is 240 degrees.
The Neck Runs on Its Own Numbers
Cervical spine ratings use the same formula with different thresholds: 30% at forward flexion of 15 degrees or less, 20% at greater than 15 but not greater than 30, and 10% at greater than 30 but not greater than 40. Normal cervical forward flexion is 0 to 45 degrees, with a combined normal of 340 degrees.
The Muscle Spasm Route to 20%
Look again at the 20% row. It doesn’t only list flexion limits.
Muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spinal contour — scoliosis, reversed lordosis, abnormal kyphosis — reaches 20% on its own, regardless of how many degrees you can bend.
Veterans who walk with a visible limp or list to one side because of their back, but whose flexion measures 70 degrees, are sitting in exactly that provision. It’s frequently overlooked because everyone is watching the protractor.
Neurologic Symptoms Rate Separately
This is the biggest single opportunity in spine claims, and it’s written into the formula as Note (1).
Any associated objective neurologic abnormalities are evaluated separately, under their own diagnostic codes — including bowel or bladder impairment.
So sciatic radiculopathy running into the leg is not part of the back rating — it’s a separate rating for that nerve, and a veteran with radiculopathy down both legs may hold two of them alongside the spine rating.
Those separate ratings then combine, which is why our guide to how VA combines ratings and the bilateral factor matters here. Bilateral lower-extremity radiculopathy is exactly the pattern the bilateral factor rewards.
The Other Formula: Incapacitating Episodes
Intervertebral disc syndrome can instead be rated on time spent incapacitated over the past 12 months — whichever method produces the higher evaluation.
| Rating | Total incapacitating episodes in the past 12 months |
|---|---|
| 60% | At least 6 weeks |
| 40% | At least 4 weeks but less than 6 |
| 20% | At least 2 weeks but less than 4 |
| 10% | At least 1 week but less than 2 |
The catch is the definition. An incapacitating episode is a period of acute signs and symptoms that requires bed rest prescribed by a physician and treatment by a physician.
Lying down for three days because your back went out doesn’t count. A physician has to have ordered the bed rest, and it has to be in the record. Veterans lose this route constantly by never asking their provider to document it.
Painful Motion Guarantees a Minimum
Section 4.59 states the schedule’s intent plainly: actually painful, unstable, or malaligned joints due to healed injury are entitled to at least the minimum compensable rating for the joint.
It also directs that joints be tested for pain on both active and passive motion, in weight-bearing and nonweight-bearing. If your exam only measured active motion while seated, it was incomplete.
Getting the Exam Right
- Don’t push through the pain. Stop where it genuinely hurts. Forcing an extra 15 degrees you couldn’t sustain gives VA a number that doesn’t reflect your life.
- Say when pain begins, not just where motion ends. The point where pain starts belongs in the report.
- Describe flare-ups concretely — how often, how long, what you can’t do during them.
- Mention repeated use. If motion worsens after a day of activity, say so; the examiner is supposed to consider it.
- Report numbness, tingling, and weakness into the arms or legs. That’s the neurologic evidence supporting a separate rating.

Frequently Asked Questions
Does pain increase my back rating?
No. The formula applies with or without pain. Measured limitation of motion, ankylosis, spasm, or guarding is what moves the rating.
What flexion gets 40% for the lower back?
Forward flexion of the thoracolumbar spine of 30 degrees or less, or favorable ankylosis of the entire thoracolumbar spine.
Can I get a separate rating for sciatica?
Yes. Objective neurologic abnormalities associated with the spine condition are rated separately under their own diagnostic codes.
What counts as an incapacitating episode?
A period of acute signs and symptoms requiring bed rest prescribed by a physician and treatment by a physician. Self-imposed rest doesn’t qualify.
Can muscle spasm alone get 20%?
Yes, when the spasm or guarding is severe enough to result in an abnormal gait or abnormal spinal contour.
What is normal range of motion for the lower back?
Forward flexion of 0 to 90 degrees, with a normal combined range of motion of 240 degrees.
Check What the Exam Actually Recorded
Request a copy of your exam report. If it omits passive motion, weight-bearing testing, flare-ups, or the neurologic findings you reported, that’s a concrete, documentable problem — not a matter of opinion.
An accredited service officer can read the report against the criteria and tell you whether the rating matches. Our guide to free help from an accredited service officer explains how to reach one, or call Post 51 at (541) 451-1351.
