Question:

EOD-Extension--Pancreas: How do you code extension when CT scan shows a mass in the head of the pancreas "encompassing" the hepatic branch of the celiac artery? See discussion.

Discussion:

We do not code the term "encompasses" as involvement. However, should we code this case as extension to the peripancreatic tissue, NOS or as unknown?

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 40 [Extension to peripancreatic tissue, NOS]. There has to be extension to peripancreatic tissue if the mass encompasses the celiac artery.
