Neoplasm of unspecified behavior of digestive system

This code represents a neoplasm within any part of the digestive system where the behavior (benign, malignant, or in situ) cannot be determined from the pathology report or clinical documentation. It indicates the presence of an abnormal growth without definitive classification of its biological nature.

Use this code when documentation specifies a "neoplasm," "tumor," or "growth" of an organ within the digestive tract (e.g., stomach, colon, liver, pancreas) but lacks further detail regarding its malignancy. This is often an interim diagnosis while awaiting biopsy results or when a definitive diagnosis of behavior is not established.

• Avoid using this code if the behavior is known (e.g., use C codes for malignant, D0 codes for in situ, D1-D3 codes for benign).
• Always seek clarification from the provider if the behavior of the neoplasm is not documented, as a more specific code may be available.
• Do not use for neoplasms of the anal margin, perianal skin, or skin of the anus, as these are specifically excluded.
