Sciatic Nerve Paralysis vs Femoral Nerve Paralysis: VA Rating Comparison
How the VA rates Sciatic Nerve Paralysis (diagnostic code 8520) compared with Femoral Nerve Paralysis (diagnostic code 8526), under 38 CFR Part 4. This is a factual side-by-side of the rating criteria, the kind veterans look up when two conditions sound similar.
Rating criteria side by side
Sciatic Nerve Paralysis
| 80% | You have complete paralysis of your sciatic nerve, which means your foot hangs down limply and you cannot lift it up or move it on its own. You cannot actively move any of the muscles below your knee, and bending your knee is either very weak or completely impossible. Your leg below the knee essentially doesn't respond to your brain's signals to move. |
|---|---|
| 60% | The nerve damage is severe but not complete, meaning you still have some function but it's significantly limited. You experience marked muscle wasting and shrinkage (atrophy) in the affected leg, which is visibly noticeable. Your symptoms would include significant weakness, difficulty walking, and substantial muscle loss in the areas controlled by the sciatic nerve. |
| 40% | You have significant but not complete paralysis of your sciatic nerve (the large nerve that runs from your lower back down through your leg). Your leg function is moderately impaired - you likely experience weakness in moving your foot up or down, difficulty walking normally, and possibly some numbness or pain, but you still have some muscle control and movement in the affected leg. |
| 20% | You have moderate nerve damage to your sciatic nerve (the large nerve that runs from your lower back down through your leg) that causes noticeable problems but doesn't completely disable the nerve function. This typically means you experience significant pain, numbness, or weakness in your leg and foot, along with some muscle weakness or partial loss of movement, but you still retain some normal nerve function and aren't completely paralyzed. |
| 10% | Your sciatic nerve damage is partial and causes only mild symptoms. This means you have some weakness, numbness, or pain in your leg and foot, but it doesn't severely limit your daily activities or prevent you from walking normally. The nerve problems are noticeable but manageable without major impact on your ability to function. |
Femoral Nerve Paralysis
| 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. |
Criteria are summarized in plain language. The controlling text is the Schedule for Rating Disabilities, 38 CFR Part 4. Full criteria for each are on the Sciatic Nerve Paralysis and Femoral Nerve Paralysis code pages.
Can both be rated at the same time?
The VA generally does not rate the same disability twice. Under the anti-pyramiding rule (38 CFR 4.14), two conditions are rated separately only when they cause distinct, non-overlapping symptoms. When the symptoms overlap, the VA assigns a single rating under whichever code best fits. Whether Sciatic Nerve Paralysis and Femoral Nerve Paralysis can be rated separately depends on the symptoms documented in the evidence. See the pyramiding guide.
