Paralysis of the lateral femoral cutaneous nerve, which may cause numbness or tingling on the outer thigh.
Medical records that describe how much sensation or motor function you have lost in the lateral thigh are central to showing where you fall in this rating. A VA or private examination documenting the degree of nerve loss — whether the paralysis is mild, moderate, severe, or complete — directly maps to the rating criteria. Nerve conduction studies or other objective test results that show the extent of impairment can help establish severity. Because complete or near-complete loss supports the 10% level while mild or moderate loss results in 0%, records that clearly describe the degree of functional loss carry the most weight. If the condition affects both thighs, documentation of bilateral involvement is needed so VA can apply the bilateral factor when combining the two ratings.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
