Question:
Primary Site--Pancreas: Should tumors with the histology "islet cell carcinoma" be coded C25.4 [Islet of Langerhans] even though the tumor location is stated to be in head of pancreas?
Discussion:
Answer:
Assign code C25.4 [Islets of Langerhans...Endocrine pancreas]. Islet cell carcinoma of the pancreas is a tumor of the endocrine pancreas. Although Islet cells are present throughout the pancreas, the best code is C25.4 to distinguish endocrine from exocrine cancers.
