Hip osteoarthritis is the diagnosis that ends most long hip stories. Years of load, an old injury nobody documented, a limp that developed slowly, and eventually an X-ray showing joint space narrowing, subchondral sclerosis, and osteophytes.
For VA purposes that X-ray is useful, because arthritis is one of the few musculoskeletal findings that is objective and dateable. It is also the point where the VA most often raises age as the alternative explanation.
How arthritis is rated
Degenerative arthritis established by X-ray findings is rated under Diagnostic Code 5003 in 38 CFR 4.71a. The structure is straightforward. Where the arthritis causes limitation of motion that is compensable under the applicable motion code, the joint is rated on that motion code - for the hip, Diagnostic Codes 5251, 5252, or 5253.
Where limitation of motion is noncompensable, Diagnostic Code 5003 provides 10 percent for a major joint with satisfactory evidence of painful motion. The hip is a major joint. Our hip rating code guide sets out the motion thresholds in detail.
Why pyramiding matters here
38 CFR 4.14 prohibits rating the same disability under multiple diagnoses. A hip cannot receive both a limitation of flexion rating and a separate arthritis rating for the same painful motion. The arthritis code fills the gap when motion is not limited enough to compensate; it does not stack on top of a motion rating for the same finding.
Separate ratings for distinct manifestations remain possible, which is a different question from double-counting one manifestation.
The aging argument, and how opinions address it
The most common reason a hip arthritis claim fails is not the absence of arthritis. It is an examiner writing that the degenerative changes are consistent with the veteran's age and unrelated to service.
A credible opinion answers that directly. It compares the affected hip to the other hip, notes asymmetric or early-onset changes, points to the documented mechanical history, and explains why the pattern of degeneration fits post-traumatic or load-related change rather than uniform age-related change. The standard is not proof; under the at least as likely as not rule, reasonable doubt is resolved in the veteran's favor.
Where veterans start
Every case is different, and there is no obligation at any step. When veterans want to understand what their records actually support, these are the two most common starting points:
- Medical records review
A licensed physician reviews your records for a $250 flat fee and identifies which conditions the available evidence may support. The fee is refunded in full if nothing supportable is identified.
- Nexus letter
When the records support one, a licensed provider writes the medical opinion that addresses the link between your condition and your service or an already service-connected disability.
What imaging should show
Plain X-rays are what the rating schedule asks for and are sufficient to establish arthritis. MRI adds value in a different way: it documents labral tears, cartilage loss, and avascular necrosis that X-ray misses, and it can establish a structural injury consistent with the in-service mechanism.
Request the radiologist's report, not just the images, and make sure it is in the claims file. An arthritis finding that only exists in a private clinic's system is not evidence the VA is reading.
- Plain X-ray of both hips, weight-bearing where possible, with the radiology report
- MRI where a labral tear, cartilage defect, or avascular necrosis is suspected
- Any prior imaging from service-era or early post-service care, even if it was read as normal
Arthritis secondary to another joint
Hip arthritis that developed because a service-connected knee, ankle, foot, or lumbar spine condition changed the way you walk is compensable under 38 CFR 3.310. This is one of the more provable secondary claims in the musculoskeletal system, because gait mechanics are well described in the medical literature and an examiner can observe the limp.
Our hip secondary to back and knee conditions guide covers what the opinion has to establish, and the knee series and back series cover the primary joints.
Where to go next
Read the C&P exam guide before your exam, and the evidence guide for what to gather. If the arthritis has progressed to joint replacement, see the hip replacement rating guide.
