BillableOsseous stenosis of neural canal of lower extremity
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Narrowing of the nerve canal in the lower leg or foot area caused by bone overgrowth, potentially affecting nerves that control leg and foot function.
Coding Tips
- •Document whether stenosis affects the right, left, or bilateral lower extremities if applicable
- •Distinguish from M99.35 (pelvic) by confirming the location is below the pelvis
