Osseous stenosis of neural canal of sacral 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 sacral region (base of spine) that narrows the nerve passage, potentially causing lower back or buttock pain.

Coding Tips

  • •Confirm sacral region involvement; this is distinct from lumbar (M99.33) and coccygeal regions
  • •Document whether stenosis affects the sacral nerve roots for clinical completeness
