ICD-10 Code G57.10 – Meralgia paresthetica, unspecified lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G57.10 – Meralgia paresthetica, unspecified lower limb
What it is
This code identifies meralgia paresthetica affecting an unspecified lower limb. It refers to pain, numbness, or tingling from lateral femoral cutaneous nerve compression or irritation; the affected side is not documented.
Clinical signs
Typical findings include burning, tingling, numbness, or pain over the outer thigh. Motor weakness is usually absent; if clinical features vary, refer to documentation.
When to use this code
Use G57.10 when the provider documents meralgia paresthetica but does not specify the right or left lower limb. It also fits notes describing lateral thigh sensory symptoms consistent with this diagnosis. If laterality is recorded, code to the specified lower-limb option instead.
Do not use for
Do not use this code when the record identifies a specific side, because laterality matters. Do not use it for generalized neuropathy, radiculopathy, or other causes of thigh pain unless documentation confirms meralgia paresthetica.
Coding tip
Check the note for laterality and exact nerve diagnosis before assigning G57.10.
