ICD-10 Code G57.01 – Lesion of sciatic nerve, right lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G57.01 – Lesion of sciatic nerve, right lower limb
What it is
G57.01 identifies a disorder affecting the sciatic nerve in the right lower limb. Use it when documentation specifies a lesion, injury, or neuropathic condition limited to the right sciatic nerve.
Clinical signs
Typical findings include pain, numbness, tingling, or weakness along the sciatic nerve distribution in the right leg. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a right-sided sciatic nerve lesion, sciatic neuropathy, or similar localized nerve disorder. It fits cases where the right lower limb is clearly identified. If the record only says “sciatica” without laterality or nerve lesion detail, check documentation.
Do not use for
Do not use this code for left-sided or unspecified sciatic nerve conditions. It is also not appropriate for back pain or radiculopathy unless the provider specifically documents sciatic nerve involvement.
Coding tip
Always confirm laterality and whether the note describes a lesion of the sciatic nerve, not just general leg pain.
