Thigh Flexion Limitation VA Disability Rating

Diagnostic Code 5252 · 38 CFR §4.71a

What Is It?

Limitation of flexion of the thigh means you cannot bend your hip as far as normal. Full hip flexion allows you to bring your knee up toward your chest to about 125 degrees. When flexion is restricted, activities like climbing stairs, getting in and out of vehicles, tying shoes, and sitting in low chairs become difficult or painful. It can be caused by arthritis, labral tears, or injuries sustained during service.

Rating Criteria

Evidence Needed

• Range of motion measurements documenting hip flexion in degrees
• Medical records establishing the cause of the flexion limitation
• Imaging showing joint damage, arthritis, or structural abnormalities
• Documentation of pain at specific points during flexion
• Statements describing functional impact on daily activities

C&P Exam Tips

• Do not push through severe pain to demonstrate more motion than you actually have on a typical day
• Report exactly where pain begins during the flexion movement
• Describe your worst days and how much less motion you have during flare-ups
• Mention activities you have given up or modified because of the limitation
• Ask the examiner to document pain, weakness, and fatigability after repetitive testing

How to File

File under DC 5252 with range of motion testing that specifically measures hip flexion in degrees. Include medical evidence linking the limitation to your service. If you also have limited extension, rotation, or abduction, those may be ratable under separate codes.

Common Mistakes

• Demonstrating maximum effort during the exam instead of showing your typical functional ability.
• Not asking the examiner to document where pain begins, which can support a higher rating under DeLuca factors.
• Failing to report flare-up frequency and the additional motion loss during flare-ups.
• Not claiming secondary conditions in the back or opposite leg.

Frequently Asked Questions

What are DeLuca factors and how do they apply?

DeLuca factors refer to additional functional loss from pain, weakness, fatigability, and incoordination during flare-ups or after repetitive use. Even if your measured range of motion falls in one rating category, these factors can support a higher rating if they cause additional functional limitation.

Should I take pain medication before my exam?

This is a personal decision, but be aware that pain medication may temporarily improve your range of motion during the exam. The exam should reflect your typical functional ability. Discuss with your doctor whether adjusting medication timing makes sense.
