Question:
Primary Site: What site code best reflects the final diagnosis of a metastatic "pancreatobiliary" adenocarcinoma to the liver? See Discussion.
Discussion:
CT showed multiple masses in the liver and lymphadenopathy in areas of gastrohepatic ligament, celiac axis, superior mesenteric and left periaortic regions. No mention of a mass in pancreas or common duct. When the term "pancreatobiliary" primary is stated in the final diagnosis, what site code should be used?
Answer:
Contact the physician for clarification of the term "pancreatobiliary." If no further information can be obtained for this case, assign code C249 [Biliary tract, NOS] based on the CT findings for the specific case in this question.
When the primary is described as "pancreatobiliary" with NO FURTHER INFORMATION, assign C269.
