Lower Back (Lumbar Spine) VA Disability Rating

Last updated 2026-05-22 · Source: 38 CFR 4.71a

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:

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

RatingForward 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:

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:

RatingIncapacitating 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:

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:

Evidence the VA looks for

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:

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:

Preparation tips:

  1. Bring a journal of flare-up frequency, duration, and severity for the past 12 months.
  2. Be specific about activities you cannot do (or can do only with significant pain). "Cannot lift my child" is more useful than "back hurts."
  3. Do NOT push through to get a better ROM measurement. The exam should reflect your true limitation.
  4. If you have radiating leg pain, mention it — it triggers a separate radiculopathy assessment.
  5. For IVDS claims, bring documentation of physician-prescribed bed rest.

Common rating pitfalls

  1. 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.
  2. 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.
  3. Not documenting flare-ups. The DeLuca / Mitchell path requires flare evidence. Keep a journal.
  4. 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.
  5. 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.
