ICD-10 Code G57.13 – Meralgia paresthetica, bilateral lower limbs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G57.13 – Meralgia paresthetica, bilateral lower limbs
What it is
G57.13 identifies meralgia paresthetica affecting both lower limbs. It refers to compression or irritation of the lateral femoral cutaneous nerve, causing sensory symptoms on the outer thighs.
Clinical signs
Typical findings include numbness, tingling, burning, or pain over the anterolateral thigh on both sides. Motor weakness is not expected; if weakness is present, check documentation for another diagnosis.
When to use this code
Use this code when the provider documents bilateral meralgia paresthetica or bilateral lateral femoral cutaneous nerve entrapment. It is appropriate when symptoms are limited to sensory disturbance in both outer thighs and the record supports a bilateral diagnosis.
Do not use for
Do not use it for unilateral meralgia paresthetica, generalized leg pain, or lumbar radiculopathy without documentation of lateral femoral cutaneous nerve involvement. If the bilateral nature is not stated, check documentation.
Coding tip
Assign G57.13 only when the record clearly states bilateral involvement; otherwise, use the documented laterality or query the provider.
