Body system: Neurological Conditions and Convulsive DisordersRegulation: 38 CFR § 4.124a
This diagnostic code covers paralysis of the quadriceps extensor muscles - the large muscle group on the front of your thigh that helps you straighten your knee and stand up from sitting. The VA rates this condition from 10% to 40% based on how severe the paralysis is, with complete paralysis earning 40% and milder cases receiving lower ratings. The ratings reflect how much the paralysis affects your ability to walk, climb stairs, and perform daily activities that require leg strength.
Rating levels
40% — Complete paralysis of the anterior crural nerve means you have total loss of function in your quadriceps muscles (the large muscles on the front of your thigh that straighten your knee). You cannot extend or straighten your knee at all because these muscles are completely paralyzed and non-functional.
30% — The femoral nerve (which controls muscles in your thigh and provides feeling to part of your leg) is severely damaged but not completely destroyed. You would have significant weakness in your thigh muscles, major difficulty straightening your leg or walking normally, and substantial numbness or loss of sensation, but you still retain some nerve function and muscle movement.
20% — You have moderate nerve damage to your femoral nerve (the main nerve that controls your thigh muscles and provides feeling to parts of your leg), but the paralysis is not complete. This means you still have some muscle function and sensation, but you experience noticeable weakness in straightening your knee, difficulty with walking or standing, and partial numbness in your thigh or inner leg area.
10% — You have mild damage to the femoral nerve (the nerve that controls your thigh muscle and provides feeling to part of your leg), but the nerve still works partially. This means you may experience some weakness in your thigh muscle or some numbness in your leg, but these symptoms are minor and don't significantly interfere with your daily activities or walking ability.
