Lesion of femoral nerve, bilateral lower limbs

This code signifies damage or dysfunction of the femoral nerve affecting both lower extremities. This can manifest as weakness, numbness, or pain in the anterior thigh, medial leg, and foot, often impacting hip flexion and knee extension. The lesion can result from various causes, including trauma, compression, or systemic conditions.

Use this code when documentation explicitly states a bilateral femoral nerve lesion. This typically involves findings such as bilateral quadriceps weakness, sensory deficits in the femoral nerve distribution on both sides, or electrodiagnostic studies confirming bilateral femoral neuropathy. Ensure the physician's notes clearly indicate the bilateral involvement.

• Confirm bilateral involvement; do not use for unilateral femoral nerve lesions.
• Distinguish from other lower limb mononeuropathies, such as sciatic or peroneal nerve lesions.
• Code any underlying cause of the femoral nerve lesion (e.g., fracture, diabetes) as a primary or secondary diagnosis.
