Hip Ankylosis VA Disability Rating
Diagnostic Code 5250 · 38 CFR §4.71a
What Is It?
Hip ankylosis means the hip joint has become permanently fixed in one position and cannot move. This can result from severe arthritis, trauma, infection, or failed surgical procedures. For veterans, hip ankylosis often develops from service-connected injuries that progressively destroyed the joint. Because the hip is essential for walking, sitting, and virtually all lower body movement, ankylosis here causes profound functional limitations.
Rating Criteria
| Rating | Criteria |
|---|---|
| 90% | Extremely unfavorable ankylosis where the hip is fixed in flexion at an angle greater than 45 degrees, or fixed in abduction, or in any combination that prevents sitting or standing without assistance. |
| 70% | Intermediate ankylosis between favorable and unfavorable positions. |
| 60% | Favorable ankylosis where the hip is fixed in flexion at an angle between 20 and 40 degrees with slight adduction or abduction. |
Evidence Needed
- Orthopedic records confirming complete loss of hip joint motion
- Imaging showing joint fusion or destruction
- Documentation of the exact position in which the hip is fixed
- Functional assessment describing impact on walking, sitting, and transfers
- Records of any assistive devices required such as wheelchairs or crutches
C&P Exam Tips
- Make sure the examiner documents that there is zero motion in the joint, not just limited motion
- Have the examiner note the exact position the hip is fixed in, as this determines the rating level
- Describe every daily activity that is affected including sitting, dressing, and hygiene
- Report whether you need assistance from another person for basic tasks
- Mention all assistive devices you use and how often
How to File
File under DC 5250. The key evidence is medical documentation proving complete absence of hip motion and the exact fixed position. If the ankylosis causes problems in other joints due to compensatory movement patterns, file those as secondary conditions.
Common Mistakes
Confusing severely limited motion with true ankylosis — the joint must be completely immobile Not having the examiner document the precise fixed position which determines whether the rating is 60, 70, or 90 Failing to claim secondary conditions in the opposite leg or back caused by the altered gait pattern Not applying for special monthly compensation for loss of use if applicable
Frequently Asked Questions
What is the difference between ankylosis and severe limitation of motion?
Ankylosis means the joint is completely immobile and fixed in one position. Severe limitation of motion means the joint still moves but very little. They are rated under different diagnostic codes and ankylosis generally receives higher ratings.
Can hip ankylosis qualify for special monthly compensation?
Yes. If the ankylosis effectively results in loss of use of the leg, you may qualify for special monthly compensation at various levels depending on the severity and whether both sides are affected.
