Neoplasm of uncertain behavior of peritoneum

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

What This Code Means

A growth in the peritoneum (the lining of the abdominal cavity) that is not clearly cancer but has uncertain behavior.

Coding Tips

  • Peritoneal tumors may be difficult to distinguish from metastatic disease; ensure pathology confirms primary peritoneal origin
  • Document whether the tumor is localized or diffuse across the peritoneal surface
