G57.92
BillableUnspecified mononeuropathy of left lower limb
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes nerve damage affecting a single nerve in the left leg, but the specific nerve involved has not been identified or documented. The condition causes weakness, numbness, or pain in the affected leg.
Coding Tips
- •Query the provider to identify the specific nerve affected (e.g., peroneal, tibial, femoral) as this will allow for a more specific code assignment and better clinical documentation
- •Ensure laterality is correctly documented as 'left' - if the condition affects the right leg or is bilateral, different codes (G57.91 or G57.90) should be used instead
