Malignant neoplasm of hepatic flexure

This code identifies a primary cancerous tumor originating in the hepatic flexure of the colon. The hepatic flexure is the bend in the colon between the ascending colon and the transverse colon, located near the liver. This malignancy is a type of colorectal cancer.

Use this code for documented primary malignant neoplasms specifically located in the hepatic flexure. This diagnosis is typically confirmed by pathology reports following biopsy or surgical resection. Documentation should clearly specify the hepatic flexure as the tumor's origin.

• Ensure the documentation specifies "hepatic flexure" and not a more general colon site (e.g., ascending colon, transverse colon) to avoid over-coding.
• Distinguish between primary malignant neoplasms and secondary (metastatic) malignancies; this code is for primary only.
• Review pathology reports for definitive site confirmation and malignancy type.
