Osseous stenosis of neural canal of rib cage

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 rib cage area caused by bone overgrowth, which can affect nerves in the chest region.

Coding Tips

  • •Verify documentation confirms rib cage location rather than thoracic spine
  • •Note any associated chest wall or intercostal nerve symptoms in the medical record
