Lesion of sciatic nerve, right lower limb

This code signifies a specific type of nerve damage affecting the right sciatic nerve, resulting in symptoms such as pain, numbness, tingling, or weakness along its distribution in the right lower extremity. It indicates a localized injury or dysfunction of this major nerve.

Apply this code when documentation clearly specifies a lesion, neuropathy, or entrapment of the sciatic nerve on the patient's right side. This is appropriate for conditions like piriformis syndrome affecting the right leg, right-sided sciatica due to disc herniation, or direct trauma to the right sciatic nerve.

• Ensure laterality is explicitly documented as "right" for the sciatic nerve involvement.
• Distinguish from generalized polyneuropathies or unspecified sciatica; this code requires a specific lesion.
• Consider an additional code for the underlying cause (e.g., disc herniation, trauma) if known and documented.
