Hallux Rigidus VA Disability Rating
Diagnostic Code 5281 · 38 CFR §4.71a
What Is It?
Hallux rigidus is a stiff big toe caused by arthritis in the joint at the base of the toe. The joint becomes increasingly difficult to bend, and bone spurs may form around it. Every step you take pushes off from this joint, so when it cannot move properly, walking becomes painful and your gait changes. The condition commonly develops from repetitive stress injuries sustained during military service, including running, rucking, and jumping.
Rating Criteria
| Rating | Criteria |
|---|---|
| 10% | Hallux rigidus that is severe and equivalent to hallux valgus requiring surgery. Rated per foot. This is the only rating level under this code and it is assigned based on the severity equaling that described under DC 5280. |
Evidence Needed
- Podiatric or orthopedic records documenting the diagnosis
- Imaging showing joint space narrowing, bone spurs, or arthritic changes
- Range of motion measurements of the big toe joint
- Documentation of pain with walking and push-off movements
- Records of treatments tried including injections or surgical consultation
C&P Exam Tips
- Have the examiner measure the range of motion of your big toe joint
- Describe how the stiffness affects your ability to walk, especially on inclines
- Report pain during the push-off phase of walking
- Show any bone spurs or swelling visible at the joint
- Mention if the condition has been discussed as potentially needing surgery
How to File
File under DC 5281 with medical evidence showing the big toe joint has significant arthritis and stiffness. Include imaging showing the joint changes and documentation of how the stiffness affects your walking.
Common Mistakes
Not providing imaging evidence showing the arthritic changes in the joint Confusing hallux rigidus with hallux valgus — rigidus is about stiffness while valgus is about angular deformity Not documenting how the toe stiffness changes your walking mechanics Failing to file for each affected foot separately
Frequently Asked Questions
What is the difference between hallux rigidus and hallux valgus?
Hallux rigidus is a stiff big toe caused by arthritis in the joint, limiting its ability to bend. Hallux valgus is a bunion where the big toe angles toward the second toe, creating a bony protrusion. They are different conditions that can coexist in the same foot.
Can hallux rigidus progress to needing surgery?
Yes. When conservative treatments like orthotics, injections, and medication no longer manage the symptoms, surgical options include joint cleaning, fusion, or joint replacement. If surgery is performed, the post-surgical condition may be ratable under the same or different codes.
