Question:

CS Eval--Colon: Should 1 [No surgical resection done...] or 3 [Surgical resection performed...] be used to correctly reflect this field when a surgical observation is "adherent to duodenum" but the extension per the pathology is stated to be to the "subserosal tissue"? See Discussion.

Discussion:

7/2/04 Op Findings 5 cm mass in mid transverse colon involving also the right colon; mass was adherent to duodenum without obvious invasion. 7/2/04 Path: Rt & Transverse Colon: 6x5 cm mass, micro: MD Adenoca with invasion of subserosal tissue; margins neg. 17/17 colic LNs negative.

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.For the case described above, code extension as 46 [Adherent to other organ...no microscopic tumor found in adhesion]. Code CS TS/Ext eval as 3 [Surgical resection performed...].

Surgery was performed for this case. The fact that the adherence to the duodenum was proven not to be tumor involvement should be coded as 3 in CS TS/Ext Eval. By using eval code 3, the case will map to a pathologic T indicating that the patient had resective surgery. Eval code 1 would map to a clinical T, incorrect for this case.
