Lumbar Spine VA Rating
TL;DR. Lumbar spine claims under DC 5237 (strain), 5242 (degenerative arthritis), and 5243 (intervertebral disc syndrome) all use the General Rating Formula in 38 CFR 4.71a. The schedular brackets are 10, 20, 40, 50, and 100 percent based on forward flexion, combined range of motion, and ankylosis. The DeLuca framework requires the examiner to consider functional loss on repetitive use and during flares. Associated radiculopathy is rated separately under DC 8520-8530 per Note 1 and combines under 38 CFR 4.25. IVDS can alternately be rated on incapacitating episodes if that produces a higher number. Most low back claims end up at 10 or 20 percent on the spine alone, but a separate radiculopathy rating often raises the combined number materially.
Which diagnostic code applies
DC 5237: lumbosacral strain
The most commonly assigned code for low back claims without confirmed disc pathology. Covers chronic strain, sprain, and myofascial pain syndromes localized to the lumbar paraspinal musculature. A veteran with no MRI findings but with persistent pain, muscle spasm, and limited motion ends up under 5237. Service treatment records showing in-service back complaints and continuity of symptomatology since separation support direct service connection under Hickson v. West, 12 Vet. App. 247 (1999).
DC 5242: degenerative arthritis of the spine
Applies when imaging confirms degenerative changes (osteophytes, facet hypertrophy, disc space narrowing without herniation). 5242 is rated under the same General Rating Formula as 5237, but the diagnosis matters for the minimum compensable provisions of 38 CFR 4.59 and Lichtenfels: painful motion of a joint with X-ray-confirmed arthritis warrants the minimum compensable rating even when ROM measurements alone would not.
DC 5243: intervertebral disc syndrome
Applies when imaging confirms disc herniation, protrusion, or extrusion causing radicular symptoms. DC 5243 can be rated under EITHER the General Rating Formula OR the Formula for Rating IVDS Based on Incapacitating Episodes, whichever yields the higher number. The incapacitating-episode method is only viable when the veteran has physician-prescribed bed rest documented in the medical record, which is uncommon outside of acute flare admissions.
The General Rating Formula brackets
The schedular brackets for the thoracolumbar spine are:
| Rating | Criteria |
|---|---|
| 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 resulting in abnormal gait or spinal contour; OR vertebral body fracture with loss of 50% or more of the 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 result in abnormal gait or abnormal spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis. |
| 40% | Forward flexion of the thoracolumbar spine 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 (cervical plus thoracolumbar). |
Note 2 to the formula defines normal motion: forward flexion 90 degrees, extension 30 degrees, lateral flexion 30 degrees each side, lateral rotation 30 degrees each side. Combined range of motion equals the sum of all six measurements. Normal combined motion is 240 degrees.
"Favorable ankylosis" means the spine is fixed in a neutral position (0 degrees). "Unfavorable ankylosis" means the spine is fixed in flexion or extension and produces additional symptoms such as difficulty walking, breathing, swallowing, or the like. Most ankylosis cases in claims practice are surgical fusions; favorable versus unfavorable turns on the post-fusion position.
The DeLuca framework: pain, weakness, fatigability on repetition
What the examiner must do
DeLuca v. Brown, 8 Vet. App. 202 (1995), held that the schedular rating must consider not just the static measurement but the functional loss on repetitive use. The C&P examiner is required to measure ROM at rest, repeat the motion three times, and document any additional loss in degrees. The examiner must also note the point in the arc where pain begins.
Mitchell v. Shinseki, 25 Vet. App. 32 (2011), clarified that pain alone does not warrant a higher rating; the pain must produce functional loss. Sharp v. Shulkin, 29 Vet. App. 26 (2017), extended the obligation: when the veteran reports flare-ups, the examiner must elicit frequency, duration, and severity and estimate the additional functional loss during a flare even if the exam is not conducted during one.
How this changes the rating
A veteran who flexes to 65 degrees at rest (10 percent bracket) but to 28 degrees after three repetitions should be rated at 40 percent (the post-repetition figure crosses the 30-degree threshold). A veteran who flexes to 45 degrees at rest with credible flare-ups limiting flexion to 20 degrees one week per month should have that flare loss factored in.
If the C&P exam does not address repetitive motion or flare-ups, the exam is inadequate under Stegall v. West, 11 Vet. App. 268 (1998), and the veteran can request a new exam or supplement with private medical evidence addressing the missing factors.
Associated neurologic abnormalities: the separate radiculopathy rating
Note 1 to the General Rating Formula
Note 1 directs: "Evaluate any associated objective neurologic abnormalities, including, but not limited to, bowel or bladder impairment, separately, under an appropriate diagnostic code." Radiculopathy is the most common associated neurologic abnormality. It is rated under the peripheral nerve schedule at DC 8520-8530.
DC 8520: sciatic nerve (the usual one for lumbar radiculopathy)
| Rating | Criteria (incomplete paralysis) |
|---|---|
| 10% | Mild incomplete paralysis |
| 20% | Moderate incomplete paralysis |
| 40% | Moderately severe incomplete paralysis |
| 60% | Severe with marked muscular atrophy |
| 80% | Complete paralysis (foot dangles and drops, no active movement of muscles below the knee, flexion of knee weakened or lost) |
Each affected lower extremity is rated separately. Bilateral radiculopathy gets two ratings that both combine into the final number under 38 CFR 4.25.
What "mild" versus "moderate" means in practice
The schedule does not define these terms. Mild is typically used for subjective complaints (numbness, tingling, occasional shooting pain) without objective neurologic findings (intact reflexes, normal strength, normal sensation on examination). Moderate adds reduced reflexes or mild sensory loss. Moderately severe adds measurable strength deficit or significant atrophy. Severe adds marked muscular atrophy. Complete paralysis is foot drop with no movement.
The radiculopathy must be documented on examination with positive straight-leg raise, dermatomal sensory loss, or reflex changes. EMG or imaging confirmation of nerve root compression supports the rating but is not strictly required if clinical findings are consistent.
IVDS: the two-formula choice
Formula for Rating IVDS Based on Incapacitating Episodes
| Rating | Total duration of incapacitating episodes over the past 12 months |
|---|---|
| 10% | At least 1 week but less than 2 weeks |
| 20% | At least 2 weeks but less than 4 weeks |
| 40% | At least 4 weeks but less than 6 weeks |
| 60% | At least 6 weeks |
Note 1 to DC 5243 defines "incapacitating episode" as a period of acute signs and symptoms due to IVDS that requires bed rest prescribed by a physician AND treatment by a physician. Self-prescribed rest does not count. The medical record must document the prescription.
For most veterans, the General Rating Formula produces the higher number because they lack physician-prescribed bed rest documentation. The incapacitating-episode method tends to apply to veterans with severe acute flares requiring ER or admitted treatment.
Worked example: combined rating with radiculopathy
Army veteran, 12 years infantry. Files claim 2025 for chronic low back pain with right leg radiation.
C&P exam findings — Diagnosis: lumbosacral strain with right L5-S1 radiculopathy. MRI shows L5-S1 disc protrusion with right-sided nerve root contact. ROM: forward flexion 55 degrees at rest, 32 degrees after three repetitions. Combined ROM 165 degrees at rest. No ankylosis. Straight-leg raise positive on the right at 40 degrees. Reduced right ankle reflex. Mild sensory loss in the right L5 and S1 dermatomes. Strength 4/5 in right ankle dorsiflexion. No atrophy.
Step 1: Pick the diagnostic code. MRI confirms disc pathology, so DC 5243 (IVDS) applies. No physician-prescribed bed rest in the record, so the General Rating Formula will produce the higher schedular number.
Step 2: Apply the General Rating Formula. Forward flexion 55 degrees at rest falls in the 20 percent bracket (greater than 30 but not greater than 60). After repetition, flexion drops to 32 degrees, still in the 20 percent bracket (the 40 percent threshold is 30 or less). DeLuca-adjusted rating: 20 percent. If post-repetition flexion had dropped to 28 degrees, the rating would jump to 40 percent.
Step 3: Rate the radiculopathy separately under Note 1. Right lower extremity sciatic nerve (DC 8520). Findings of positive SLR, reduced reflex, sensory deficit, and 4/5 strength without atrophy fit "moderate" incomplete paralysis. Rating: 20 percent right lower extremity.
Step 4: Combine under 38 CFR 4.25. Spine 20 + right radiculopathy 20. Combined-rating table: 20 combined with 20 = 36, rounds to 40 percent.
Step 5: 2026 monthly compensation. 40 percent with spouse = $902.81 per month. If the spine had been 10 percent and radiculopathy 10 percent, the combined would be 19, rounding to 20 percent at $402.74 per month. The separate radiculopathy rating adds approximately $500 per month in this scenario.
Note on what to watch for. If the veteran later develops bilateral radiculopathy, the left lower extremity gets its own DC 8520 rating that also combines in. If the radiculopathy progresses to moderately severe (clear atrophy, strength below 4/5), the per-leg rating jumps to 40 percent and the combined number moves materially.
