Lesion of femoral nerve, right lower limb

This code signifies damage or dysfunction of the femoral nerve specifically affecting the right lower extremity. This can manifest as sensory disturbances (numbness, tingling) or motor weakness (difficulty with knee extension or hip flexion) in the distribution of the right femoral nerve.

Apply this code when documentation clearly indicates a diagnosed lesion, neuropathy, or entrapment of the right femoral nerve. This includes conditions like femoral nerve palsy, mononeuropathy, or injury affecting this specific nerve on the right side. Supporting documentation should detail the affected nerve and laterality.

• Ensure documentation specifies "right" lower limb; otherwise, an unspecified laterality code may be more appropriate.
• Distinguish from other lower limb nerve lesions (e.g., sciatic, peroneal) based on the nerve affected.
• Look for etiology (e.g., trauma, compression) which may require an additional code.
