Question:

EOD-Extension--Liver: Can we use CT scan descriptions such as "portal vein thrombosis" or "extensive infiltration of the liver" or "diffuse infiltration of the liver" to code extension for liver primaries? See discussion.

Discussion:

1. Would you code portal vein involvement for a CT scan description of "portal vein thrombosis"?

2. Would you code more than one lobe of the liver as involved for CT scan descriptions of "extensive infiltration of the liver" or "diffuse infiltration of the liver"?

Answer:

For cases diagnosed 1998-2003:

1. No. Thrombosis can be caused by non-cancerous conditions.

2. Yes. Code the EOD-Extension field to 65 [Multiple (satellite) nodules in more than one lobe of the liver] when "extensive infiltration" or "diffuse infiltration" is stated.
