Question:

EOD-Extension--Pancreas: How do you code extension when a mass is described on exploratory laparotomy as compressing the duodenum, arising in the head of the pancreas, "extending around" the superior mesenteric vein and artery, and "encasing" the portahepatis?

Discussion:

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 40 [extension to peripancreatic tissue, NOS]. Neither of the terms "extending around" nor "encasing" are interpreted as involvement with tumor by SEER.
