Lower Back (Lumbar Spine) VA Disability Rating
TL;DR. Lower back conditions are rated under the General Rating Formula for the Spine (38 CFR 4.71a) at 10/20/40/50%. The primary measurement is forward flexion of the thoracolumbar spine. Most rated veterans land at 10% or 20%. Secondary radiculopathy (sciatica, DC 8520) rates separately per affected limb. Bilateral radiculopathy invokes the 38 CFR 4.26 bilateral factor. Chronic pain from a rated back commonly supports secondary depression / anxiety claims. The DeLuca / Mitchell case law on functional loss is critical for veterans whose measured ROM looks better than their actual function.
What lumbar spine conditions the VA rates
The General Rating Formula for the Spine covers most chronic back conditions under several diagnostic codes:
- DC 5235 — Vertebral fracture or dislocation.
- DC 5236 — Sacroiliac injury and weakness.
- DC 5237 — Lumbosacral or cervical strain. The most common lumbar rating code.
- DC 5238 — Spinal stenosis.
- DC 5239 — Spondylolisthesis or segmental instability.
- DC 5240 — Ankylosing spondylitis.
- DC 5241 — Spinal fusion.
- DC 5242 — Degenerative arthritis of the spine.
- DC 5243 — Intervertebral disc syndrome (IVDS). Has an alternative rating path based on incapacitating-episode frequency.
The primary rating measurement for ALL of these (except IVDS which has an alternative path) is forward flexion of the thoracolumbar spine. The thoracolumbar spine spans T1 through S1 — the upper-mid back through the sacrum. Cervical spine (neck) conditions use the same brackets with slightly different ROM thresholds (see cervical spine page).
How the VA rates lumbar spine conditions
| Rating | Forward flexion criteria (thoracolumbar) |
|---|---|
| 10% | Forward flexion greater than 60° but not greater than 85°, OR; combined ROM greater than 120° but not greater than 235°, OR; muscle spasm/guarding/localized tenderness not resulting in abnormal gait or spinal contour, OR; vertebral body fracture with loss of 50% or more of height. |
| 20% | Forward flexion greater than 30° but not greater than 60°, OR; combined ROM not greater than 120°, OR; muscle spasm/guarding severe enough to result in abnormal gait or spinal contour. |
| 40% | Forward flexion 30° 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 (cervical + thoracolumbar). |
Key points:
- "Combined ROM" sums forward flexion, extension, left and right lateral flexion, and left and right rotation. Combined ROM is rarely the deciding measurement — forward flexion is usually the limiting factor first.
- Ankylosis (40% and 50% brackets) is fusion of the spine. True ankylosis is rare; most veterans land at 10% or 20%.
- The 40% bracket has TWO paths: severely limited flexion (30° or less) OR favorable ankylosis. Either alone qualifies for 40%.
- The 50% bracket requires UNfavorable ankylosis — the spine fixed in a non-neutral position (flexed forward, etc.). This is functionally devastating and rates accordingly.
The alternative path: Intervertebral Disc Syndrome (IVDS)
DC 5243 (IVDS) has an alternative rating path based on incapacitating-episode frequency over the past 12 months:
| Rating | Incapacitating episodes (past 12 months) |
|---|---|
| 10% | 1 week, but less than 2 weeks total. |
| 20% | 2 weeks, but less than 4 weeks total. |
| 40% | 4 weeks, but less than 6 weeks total. |
| 60% | 6 weeks or more total. |
An "incapacitating episode" is defined as bed rest prescribed by a physician AND treatment by a physician. Self-imposed bed rest does NOT count. The rater takes whichever produces the higher rating: General Formula (ROM-based) or IVDS path (incapacitating-episodes-based). They cannot be added together.
Service-connection paths
Direct service connection
Most lumbar claims succeed on direct connection because back injuries are extremely common in service. Evidence:
- STR entries documenting back complaints, sick call visits, profile restrictions;
- Documentation of a specific in-service injury (PT injury, fall, lifting injury, motor vehicle accident);
- Personnel records showing physically demanding MOS;
- Buddy statements confirming in-service back complaints.
The continuity-of-symptomatology doctrine (38 CFR 3.303(b)) is especially relevant for back claims because chronic back pain often progresses gradually post-service. A veteran with even minor in-service back complaints, plus current chronic back symptoms, can win on direct connection.
Secondary service connection
Lower back can be secondary to other service-connected conditions:
- Knee, hip, or ankle condition. Altered gait mechanics from a lower-extremity injury drive secondary back strain. Common in veterans with rated knee conditions.
- Foot conditions (plantar fasciitis, pes planus). Same gait-mechanics theory.
- Cervical spine condition. Compensatory mechanics from cervical limitation can drive lumbar strain.
Evidence the VA looks for
- Current diagnosis from a primary care provider, orthopedist, or spine specialist.
- Imaging (X-ray, MRI). Often shows degenerative changes consistent with the rating. MRI is particularly useful for IVDS and herniation claims.
- ROM measurements. Either from your treating provider or the C&P examiner. The General Formula requires goniometer-measured flexion.
- STR back entries. Any in-service complaints, profiles, or injuries.
- Current treatment records. Physical therapy notes, prescriptions, injections, surgical history.
- Records of flare-ups. Crucial for the DeLuca / Mitchell functional-loss analysis (see below).
- For IVDS: physician-prescribed bed rest documentation. Without this, the General Formula path applies regardless of subjective severity.
The DeLuca / Mitchell functional-loss principle
Two Court of Appeals for Veterans Claims cases — DeLuca v. Brown (1995) and Mitchell v. Shinseki (2011) — require the VA to consider functional loss due to pain, weakness, fatigability, and incoordination DURING FLARE-UPS, not just measured ROM at rest. The rater must elevate the rating if the veteran's functional limitation during flares would meet a higher bracket.
In practice this means:
- If your ROM measurement is 65° (in the 10% bracket) but you have weekly flare-ups during which you can barely flex 25° (40% bracket), the rater should consider the higher bracket.
- Documentation of flare-ups is critical. Keep a journal of flare frequency, duration, severity, and functional impact.
- The C&P examiner is required to ask about flare-ups specifically. Be detailed and specific.
Many under-rated back claims hinge on DeLuca/Mitchell. If your decision letter shows the rating was based solely on measured ROM without flare consideration, an appeal citing this case law often succeeds.
The lumbar C&P exam
The exam uses DBQ 21-0960M-14 (Back Conditions). Structure:
- History of the condition;
- Functional limitation assessment;
- Goniometer-measured ROM (forward flexion, extension, lateral flexion, rotation);
- Palpation for tenderness, spasm, guarding;
- Neurological screen for radiculopathy;
- Flare-up questioning (required by DeLuca / Mitchell);
- Documentation of any incapacitating episodes (for IVDS rating);
- Functional impact on work and daily activities.
Preparation tips:
- Bring a journal of flare-up frequency, duration, and severity for the past 12 months.
- Be specific about activities you cannot do (or can do only with significant pain). "Cannot lift my child" is more useful than "back hurts."
- Do NOT push through to get a better ROM measurement. The exam should reflect your true limitation.
- If you have radiating leg pain, mention it — it triggers a separate radiculopathy assessment.
- For IVDS claims, bring documentation of physician-prescribed bed rest.
Common rating pitfalls
- Forgetting to claim radiculopathy. If you have leg numbness, tingling, or radiating pain, file radiculopathy as a separate claim under DC 8520. It rates separately and substantially raises the combined picture.
- Missing the bilateral factor. If you have bilateral radiculopathy (both legs), the 38 CFR 4.26 bilateral factor adds 10% to the combined value of the paired ratings.
- Not documenting flare-ups. The DeLuca / Mitchell path requires flare evidence. Keep a journal.
- Choosing the wrong rating path. If you have severe IVDS with documented bed rest, the IVDS path may produce a higher rating than the General Formula. The rater should choose the higher path automatically; appeal if they didn't.
- Filing back alone when secondary mental-health is available. Chronic back pain commonly supports secondary depression / anxiety claims that substantially raise the combined rating.
Worked example
Veteran: Army, 11B infantry, multiple deployments. Lumbar strain documented in STRs (helicopter crash 2008). Current: forward flexion 35°, weekly flare-ups, bilateral radiculopathy (mild left, moderate right). No spouse, no children.
- Lumbar strain rating: 20% (flexion 30–60°).
- Left radiculopathy: 10% (mild).
- Right radiculopathy: 20% (moderate).
- Bilateral factor: The two radiculopathies are paired. Combine first: 20 + 10 × 0.80 = 28. Add 10% bilateral: 28 + 2.8 = 30.8. This 30.8 is the value combined with the lumbar rating.
- Final combine: Sorted high-low: 30.8 (radiculopathy paired+bilateral), 20 (lumbar). 30.8 + 20 × 0.692 = 44.64 → rounded 40%.
- 2026 monthly compensation (alone, 40%): $755.28/mo.
- If depression secondary to chronic pain is added at 30%: Combined: 44.64 + 30 × 0.554 = 61.3 → rounded 60%; $1,361.88/mo.
Stacking secondaries (radiculopathy + bilateral + depression) takes a 20% back claim to 60% combined — +$606.60/mo, +$7,279/year.
