Meralgia paresthetica, left lower limb

This code signifies a mononeuropathy affecting the lateral femoral cutaneous nerve in the left lower extremity, characterized by numbness, tingling, burning pain, and sensory loss on the outer thigh. It results from compression or entrapment of this nerve, typically near the anterior superior iliac spine.

Apply this code when documentation clearly indicates a diagnosis of meralgia paresthetica specifically affecting the patient's left thigh. Supporting documentation should detail the characteristic sensory symptoms and their localization to the distribution of the left lateral femoral cutaneous nerve.

• Ensure laterality is explicitly documented as "left" to support this specific code.
• Differentiate from other neuropathies of the lower limb; this condition is purely sensory.
• Do not use for bilateral involvement or for the right lower limb; specific codes exist for those scenarios.
