Osseous stenosis of neural canal of lumbar region

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Bone overgrowth in the lower back spine that narrows the nerve passage, potentially causing lower back pain, leg pain, or numbness.

Coding Tips

  • •Document the specific lumbar vertebral level (L1-L5) when available for clinical detail
  • •This is a common code; ensure osseous stenosis is confirmed and not confused with disc-related stenosis
