Neoplasm of uncertain behavior of retroperitoneum

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

What This Code Means

A growth in the retroperitoneum (the space behind the abdominal cavity) that is not clearly cancer but has uncertain behavior.

Coding Tips

  • •Retroperitoneal tumors are often discovered incidentally on imaging; ensure the uncertain behavior is confirmed by pathology
  • •Document the specific location within the retroperitoneum if possible for clinical clarity
