Neoplasm of uncertain behavior of other and unspecified digestive organs

This code signifies a tumor within the digestive system whose biological behavior cannot be definitively classified as benign or malignant based on current diagnostic information. It indicates that the pathologist has observed features that are atypical but not conclusive for malignancy, requiring further investigation or monitoring.

Apply this code when pathology reports describe a neoplasm of the digestive organs (excluding stomach, small intestine, colon, rectum, anus, liver, gallbladder, and pancreas, which have more specific codes) as "uncertain behavior," "borderline malignancy," or "atypical proliferation of uncertain significance." Documentation must clearly state the uncertain nature of the tumor and its location within an "other" or "unspecified" digestive organ.

• Ensure the documentation specifies a digestive organ not covered by more specific "uncertain behavior" codes (e.g., esophagus, appendix, peritoneum).
• Do not use this code if the pathology definitively states benign or malignant; use the appropriate benign or malignant neoplasm code.
• Always review the full pathology report for the most precise diagnosis and behavior classification.
