Meralgia paresthetica, bilateral lower limbs

This code represents a neurological condition characterized by numbness, burning pain, or tingling in the outer thigh due to compression of the lateral femoral cutaneous nerve. Specifically, it indicates that this nerve entrapment syndrome affects both lower limbs.

Apply this code when documentation clearly states a diagnosis of meralgia paresthetica affecting both the right and left lower extremities. Supporting documentation should include physical exam findings consistent with lateral femoral cutaneous nerve neuropathy bilaterally, such as sensory deficits in the anterolateral thigh.

• Ensure documentation explicitly states "bilateral" involvement; otherwise, use the appropriate unilateral code (G57.11 or G57.12).
• Distinguish from other neuropathies of the lower limb (e.g., G57.0- for sciatic nerve disorders) based on the specific nerve affected.
• Look for associated causes like obesity, tight clothing, or pregnancy, which may be documented but do not change the primary diagnosis code.
