Question:

EOD-Extension--Pancreas: Can you explain the difference between code 10 [confined to pancreas] and code 30 [Localized, NOS]. See discussion.

Discussion:

For example, a CT scan mentions no extension beyond the head, body or tail of the pancreas and there is no surgical resection. Should we code extension to 10 or 30?

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 10 [confined to pancreas] because a scan supported the finding of no extension beyond the pancreas.

If the abstractor reviewing the medical record has scans, op reports, and/or pathology reports stating that the tumor is confined to the pancreas, code extension to 10 [confined to pancreas].

However, if the medical record only provides a patient history from a physician stating that the patient had localized pancreas, code extension to 30 [localized, NOS]. The NOS codes are used only when there is not enough information to code the specific codes (in this case, 10 or 20).
