Bones & Joints — VA Disability Ratings

How Bones & Joints conditions are rated

The musculoskeletal schedule is the largest in the rating system and the one most veterans meet first. It covers degenerative and rheumatoid arthritis, limitation of motion at every major joint, spine and disc conditions, knee instability, foot and ankle injuries, fractures and their residuals, prosthetic joint replacements, and amputations. The rating criteria live in 38 CFR §4.71a, and the range-of-motion measurements they depend on are defined in §4.71.

Most of this schedule rates loss of motion, and the numbers are joint-specific: what earns 10% at the knee is not what earns 10% at the shoulder. Two rules cut across all of them. First, §4.59 provides that actually painful, unstable, or malaligned joints are entitled to at least the minimum compensable rating for that joint — so a joint that hurts through its motion should not come back at 0% just because the degrees measured well. Second, §4.40 and §4.45 require the examiner to account for functional loss beyond the raw measurement: weakness, excess fatigability, incoordination, and additional loss of motion during flare-ups and after repeated use. Those are the DeLuca factors, and an examination that records only a single best-effort measurement has not applied them.

Arthritis has its own structure. Under DC 5003, degenerative arthritis established by X-ray is rated on limitation of motion under the code for the joint involved. Where limitation of motion exists but is noncompensable under that code, a 10% evaluation applies for each major joint or group of minor joints affected. Where there is no limitation of motion at all, X-ray evidence involving two or more major joints or minor joint groups supports 10%, and 20% when there are occasional incapacitating exacerbations — but those X-ray-based ratings are not combined with ratings based on limitation of motion. §4.45 defines the terms: the shoulder, elbow, wrist, hip, knee, and ankle are major joints, while the finger, toe, carpal, tarsal, and vertebral joints are grouped as minor joints.

The spine is rated under a single General Rating Formula that applies whether the diagnosis is degenerative disc disease, spinal stenosis, strain, or vertebral fracture, and it turns on forward flexion in degrees, on combined range of motion, and at the higher levels on ankylosis. Muscle spasm or guarding severe enough to produce an abnormal gait or abnormal spinal contour supports 20% on its own. Intervertebral disc syndrome may instead be rated on incapacitating episodes — periods of bed rest prescribed by a physician — using whichever method produces the higher evaluation. The provision veterans most often miss sits in a note to that formula: associated objective neurologic abnormalities, including radiculopathy and bowel or bladder impairment, are evaluated separately under their own diagnostic codes.

Three rules shape what the combined total ends up being. The bilateral factor at §4.26 adds 10% of the combined value when disabilities affect both arms or both legs, applied before those ratings are combined with anything else — which matters constantly here, because musculoskeletal injuries are so often symmetrical. The amputation rule at §4.68 caps the combined rating for one extremity at what amputation at the elective level would pay. And the anti-pyramiding rule at §4.14 bars rating the same impairment twice — though separate ratings for genuinely different impairments of one joint, such as limitation of motion under one code and instability under another, are permitted and are frequently overlooked.
