Meralgia paresthetica

This code represents meralgia paresthetica, a mononeuropathy characterized by pain, numbness, or burning sensations on the outer thigh. It results from compression or entrapment of the lateral femoral cutaneous nerve (LFCN).

Apply this code when documentation clearly indicates a diagnosis of meralgia paresthetica, often presenting with sensory symptoms in the distribution of the LFCN. This diagnosis is typically made based on clinical examination and patient history, sometimes supported by nerve conduction studies.

• Ensure documentation specifies "meralgia paresthetica" or "lateral femoral cutaneous nerve entrapment" to support this specific code.
• Do not confuse with other neuropathies affecting the lower extremity; verify the nerve involved.
• Consider any underlying causes documented, such as obesity, tight clothing, or trauma, but code the meralgia paresthetica as the primary diagnosis if it is the reason for the encounter.
