VA Rating for Back Pain: How the Spine Formula Works in 2026
The VA rates most back conditions by how far you can bend forward. For the lower and mid back (the thoracolumbar spine), forward flexion over 60 but not over 85 degrees is 10%, over 30 but not over 60 degrees is 20%, and 30 degrees or less is 40%. Ankylosis (a fused spine) is rated at 40%, 50% or 100%. Nerve pain down the leg is rated separately. Here is how it works and how to get an accurate exam.
TL;DR
- Back conditions are rated under the General Rating Formula for Diseases and Injuries of the Spine in 38 CFR 4.71a. Thoracolumbar ratings are 10%, 20%, 40%, 50% and 100%.
- The key measurement is forward flexion: 30 degrees or less is 40%, over 30 up to 60 is 20%, over 60 up to 85 is 10%. Normal is 90 degrees.
- Sciatica or radiculopathy is rated on its own, usually under DC 8520 (sciatic nerve) at 10% to 80% per leg, on top of the back rating (Note 1 to the spine formula).
- Disc disease with nerve root involvement (DC 5243) can instead be rated on incapacitating episodes: 10% to 60%, but only for bed rest prescribed by a physician.
- The exam must account for pain, flare-ups and repeated use (38 CFR 4.40, 4.45, 4.59; DeLuca, Correia, Sharp). A written flare-up log helps you describe them accurately.
How does the VA rate back pain?
The VA does not rate back pain by how much it hurts on a scale of 1 to 10. It rates by what your spine can do. Most back diagnoses, including strain, stenosis, spondylolisthesis, fusion, and degenerative arthritis or disc disease, fall under diagnostic codes 5235 to 5243 in 38 CFR 4.71a.
All of those codes use one rating formula. It applies "with or without symptoms such as pain (whether or not it radiates), stiffness, or aching." That means the numbers on the goniometer drive the rating, but pain still matters because it can limit how far you move.
The VA rates the lower and mid back (thoracolumbar spine) and the neck (cervical spine) as separate disabilities, unless both are fused in an unfavorable position (Note 6).
What are the VA ratings for the lower back?
Here is the thoracolumbar part of the General Rating Formula, from 38 CFR 4.71a. You only need to meet one of the listed findings in a row to qualify for that rating.
| Rating | Thoracolumbar spine findings |
|---|---|
| 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 that does not cause an abnormal gait or spinal contour; or a vertebral body fracture with loss of 50% or more of its height |
| 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 an abnormal gait or abnormal spinal contour (scoliosis, reversed lordosis, abnormal kyphosis) |
| 40% | Forward flexion 30 degrees or less; or favorable ankylosis of the entire thoracolumbar spine |
| 50% | Unfavorable ankylosis of the entire thoracolumbar spine |
| 100% | Unfavorable ankylosis of the entire spine |
Normal forward flexion of the thoracolumbar spine is 0 to 90 degrees. Normal extension is 0 to 30 degrees, and normal side bending and rotation are 0 to 30 degrees each way. The combined range of motion adds all six movements. Normal combined motion is 240 degrees (Note 2). Each measurement is rounded to the nearest 5 degrees (Note 4).
Past 40%, there is no higher rating based on range of motion alone. The 50% and 100% levels require ankylosis, which means the spine is fixed in place.
What about the neck?
The same formula rates the cervical spine with different numbers. Forward flexion of the neck greater than 30 but not greater than 40 degrees is 10%. Greater than 15 but not greater than 30 degrees is 20%. Fifteen degrees or less, or favorable ankylosis of the entire cervical spine, is 30%. Unfavorable ankylosis of the entire cervical spine is 40% (38 CFR 4.71a). Normal neck flexion is 0 to 45 degrees.
Is sciatica or radiculopathy rated separately?
Yes. Note 1 to the spine formula tells the VA to rate "any associated objective neurologic abnormalities" separately under the right diagnostic code. That includes nerve pain, numbness or weakness in the legs, and bowel or bladder problems.
Radiculopathy down the leg is usually rated under DC 8520, the sciatic nerve, in 38 CFR 4.124a. Each leg is rated on its own:
| DC 8520 level | Rating |
|---|---|
| Mild incomplete paralysis | 10% |
| Moderate incomplete paralysis | 20% |
| Moderately severe incomplete paralysis | 40% |
| Severe incomplete paralysis, with marked muscular atrophy | 60% |
| Complete paralysis (foot dangles and drops) | 80% |
When both legs have a compensable rating, the bilateral factor in 38 CFR 4.26 adds 10% of their combined value before everything else is combined. Many veterans rated for their back never get the leg ratings because nobody asked about the nerve symptoms. See our secondary conditions guide for how these links work.
How does the IVDS incapacitating episode formula work?
Intervertebral disc syndrome (IVDS) has its own code, DC 5243. Since the 2021 update to the musculoskeletal rules, the VA assigns DC 5243 only when there is a disc herniation with compression or irritation of the nerve root. Other disc diagnoses go under DC 5242.
IVDS can be rated under the General Rating Formula or under the incapacitating episode formula, whichever gives the higher result once all ratings are combined under 38 CFR 4.25.
| Total incapacitating episodes in the past 12 months | Rating |
|---|---|
| At least 1 week but less than 2 weeks | 10% |
| At least 2 weeks but less than 4 weeks | 20% |
| At least 4 weeks but less than 6 weeks | 40% |
| At least 6 weeks | 60% |
The catch is the definition. An incapacitating episode is a period of acute symptoms "that requires bed rest prescribed by a physician and treatment by a physician" (Note 1 to the IVDS formula). Days you stayed in bed on your own do not count. If a doctor orders bed rest, make sure it is written in your records with the dates.
Track flare-ups and bed rest days with the Symptom and Flare-Up Logbook ($19), so your dates and details are on paper before the exam.
How does pain affect a back rating? (DeLuca, 4.40, 4.45, 4.59)
Range of motion is not just where the joint stops. It is where you can actually use it. Three rules make the VA look at real function:
- 38 CFR 4.40 says functional loss can be due to pain, and "a part which becomes painful on use must be regarded as seriously disabled."
- 38 CFR 4.45 lists weakened movement, excess fatigability, incoordination, and pain on movement as factors to check.
- 38 CFR 4.59 says painful motion is a key factor, and joints should be tested for pain on active and passive motion, in weight-bearing and non-weight-bearing.
In DeLuca v. Brown, 8 Vet. App. 202 (1995), the court held that ratings must account for functional loss from pain, weakness, fatigability and incoordination, including during flare-ups and after repeated use. Mitchell v. Shinseki, 25 Vet. App. 32 (2011), added that pain alone is not the same as functional loss, but the examiner must address flare-ups and repetitive use.
In Correia v. McDonald, 28 Vet. App. 158 (2016), the court held that an exam must include the testing in 4.59: active and passive motion, weight-bearing and non-weight-bearing. An exam without it can be inadequate.
What if my back is worse during flare-ups? (Sharp v. Shulkin)
Most exams happen on an average day. Sharp v. Shulkin, 29 Vet. App. 26 (2017), says an examiner who does not see you during a flare-up must still estimate the extra loss of motion during flare-ups. The examiner should use your own description to do it, or explain why an estimate is not possible.
That puts weight on what you say. Be ready to answer clearly:
- How often do flare-ups happen (per week or month)?
- How long does each one last?
- What sets them off (lifting, sitting, driving, weather)?
- What can you not do during one (bend to tie shoes, sit through a shift, pick up a child)?
- About how far can you bend forward during one compared with today?
A log kept over a few months answers these with dates instead of guesses. Describe your real worst days accurately and completely. Do not add to them. The goal is an exam that reflects how your back actually works.
How does a C&P range of motion exam work?
The examiner uses a goniometer, a hinged ruler that measures joint angles in degrees. For the back you stand and bend forward, lean back, bend to each side and twist to each side. The examiner records each angle and where pain begins.
The exam form also asks the examiner to test after repeated use, to see if you lose motion. Tell the examiner when pain starts. Stop when pain stops you. Do not push through pain to reach a number, and do not stop short of what you can do.
The examiner fills out the Back (Thoracolumbar Spine) Conditions Disability Benefits Questionnaire. Our C&P exam tips page covers the full exam, how to get a copy, and what makes an exam inadequate.
What should I bring to a back exam?
- A short list of your flare-ups over the last few months: dates, length, and what you could not do.
- Dates of any physician-prescribed bed rest.
- A list of devices you use: brace, cane, TENS unit.
- Notes on leg symptoms: numbness, tingling, weakness, which leg, how often.
- A personal statement or buddy statement already sent to the VA, if you have one.

Frequently asked questions
What is the most common VA rating for back pain?
The VA does not publish a single number, but 10%, 20% and 40% are the range-of-motion levels under the spine formula. Which one fits depends on your forward flexion and combined range of motion at the exam (38 CFR 4.71a).
Can I get a separate rating for sciatica?
Yes. Note 1 to the spine formula requires neurologic problems to be rated separately. Leg radiculopathy is usually rated under DC 8520 at 10% to 80% per leg, based on how severe it is.
Does bed rest count if my doctor did not order it?
Not for the IVDS incapacitating episode formula. It counts only when a physician prescribes the bed rest and treats you. Self-directed rest can still be described as part of your flare-ups.
What is the highest VA rating for the back based on motion?
40% for the thoracolumbar spine, at 30 degrees or less of forward flexion. The 50% and 100% levels require unfavorable ankylosis. IVDS can reach 60% under the incapacitating episode formula.
What if the examiner did not ask about flare-ups?
An exam that skips flare-ups or the 4.59 testing may be inadequate under Sharp, Correia and Barr v. Nicholson. You can point this out in a Higher-Level Review or submit new evidence in a Supplemental Claim.
