M99.76
BillableConnective tissue and disc stenosis of intervertebral foramina 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 passages in the spine due to connective tissue and disc problems affecting the lower leg and foot area, potentially causing leg pain or weakness.
Coding Tips
- •Ensure documentation specifies lower extremity involvement; this includes hip, thigh, knee, leg, and foot regions
- •Distinguish from upper extremity codes (M99.77) by carefully reviewing the anatomical location documented
