Lesion of femoral nerve, left lower limb

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

Use this code when documentation clearly indicates a diagnosed lesion, neuropathy, or injury impacting the femoral nerve of the patient's left leg. Supporting documentation includes neurological examination findings, electromyography (EMG), nerve conduction studies (NCS), or imaging reports confirming the nerve involvement.

• Specify laterality; this code is for the left lower limb only.
• Distinguish from other lower limb neuropathies; ensure the documentation explicitly points to the femoral nerve.
• Consider an external cause code if the lesion is due to trauma or iatrogenic injury.
