Billable

Carcinoma in situ of trachea

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

What This Code Means

Abnormal cells found in the trachea (windpipe) that have the potential to become cancer but have not yet invaded deeper tissues.

Coding Tips

  • •Ensure documentation clearly identifies the trachea as the site, not the larynx or bronchi
  • •Distinguish from invasive tracheal cancer (C33.x codes)
