Neoplasm of uncertain behavior of oth digestive organs

This code signifies a tumor of the digestive system whose biological behavior (benign or malignant) cannot be definitively determined from pathological examination. It applies to neoplasms located in digestive organs other than those with more specific codes for uncertain behavior.

Use this code when pathology reports indicate a neoplasm of uncertain or unknown behavior in digestive organs such as the esophagus, stomach, small intestine, large intestine, or pancreas, and a more specific code for that organ is not available. Documentation must clearly state the uncertain nature of the tumor and its location within a specified digestive organ.

• Always review the pathology report for definitive malignant or benign diagnoses before assigning this code.
• Differentiate carefully between "uncertain behavior" and "unspecified behavior" (D49.x codes), which implies insufficient information.
• Ensure the specified digestive organ is not covered by another, more precise D37.x code.
