ICD-10 Code G57.11 – Meralgia paresthetica, right lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G57.11 – Meralgia paresthetica, right lower limb
What it is
G57.11 identifies meralgia paresthetica affecting the right lower limb. It refers to compression or irritation of the lateral femoral cutaneous nerve causing sensory symptoms in the outer thigh.
Clinical signs
Typical findings include numbness, burning, tingling, or pain over the anterolateral right thigh. Motor weakness is not expected; if symptoms are atypical, check documentation.
When to use this code
Use this code when the record clearly states meralgia paresthetica on the right side or documents lateral femoral cutaneous nerve entrapment affecting the right lower limb. Code it from provider assessment, not from nonspecific thigh pain alone. If laterality is missing, check documentation.
Do not use for
Do not use it for generalized leg pain, lumbar radiculopathy, or meralgia paresthetica without right-side documentation. If the chart only says “thigh numbness,” check documentation.
Coding tip
Confirm laterality and the provider’s diagnosis before assigning G57.11.
