G57.93

What This Code Means

This code describes nerve damage affecting both legs where the specific type of nerve damage has not been identified or documented. The condition causes weakness, numbness, or pain in the lower limbs due to problems with individual nerves.

Coding Tips

• •Use this code only when the mononeuropathy is confirmed to be bilateral (affecting both legs) but the specific nerve or cause cannot be determined; if the specific nerve is identified, use a more specific G57 code
• •Verify documentation supports bilateral involvement; if only one leg is affected, use the unilateral code G57.90 instead, and ensure any underlying causes (diabetes, trauma, compression) are coded separately if documented
