Secondary malignant neoplasm of other digestive organs

This code signifies the spread of cancer from a primary site to other digestive organs not specifically categorized elsewhere. This includes metastatic disease affecting organs such as the mesentery, omentum, or peritoneum, when the primary tumor originated in a different location. It indicates that these digestive structures are now involved with malignant cells secondary to another cancer.

Apply this code when documentation clearly states metastatic carcinoma to digestive organs not covered by more specific codes (e.g., liver, stomach, colon). This is appropriate when the primary malignancy is known and has spread to these "other" digestive sites. Supporting documentation includes pathology reports confirming metastatic disease and imaging studies identifying tumor involvement in these specified areas.

• Always sequence the primary malignancy first, followed by this code for the secondary site.
• Do not use this code if the secondary malignancy is specified to a more precise digestive organ (e.g., liver, pancreas, small intestine); use the specific secondary malignancy code for that organ instead.
• Ensure the documentation differentiates between primary and secondary involvement; this code is exclusively for metastatic disease.
