Fusion of spine, thoracolumbar region

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

What This Code Means

A surgical fusion procedure spanning the thoracolumbar region (where the mid-back and lower back meet) to stabilize multiple vertebrae.

Coding Tips

  • •Confirm the fusion extends across the thoracolumbar junction; if fusion is only in thoracic or lumbar region alone, use the appropriate single-region code
  • •Document whether this is a post-surgical status or if the fusion is causing current complications or functional limitations
