Billable

Neoplasm of uncertain behavior of liver, gallbladder and bile ducts

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

What This Code Means

A growth in the liver, gallbladder, or bile ducts that cannot yet be determined to be cancer or benign. These tumors require further testing and monitoring to establish their true nature.

Coding Tips

  • Use this code when pathology reports indicate 'uncertain behavior' or 'borderline' findings in hepatobiliary tissues
  • Ensure imaging or biopsy results are documented to support the uncertain behavior classification
