Question:
Histology (Pre-2007)--Colon: What code is used to represent histology when the surgeon describes a sessile polyp and the final path diagnosis is stated as: "Rectal sessile polyp: Invasive moderately differentiated adenocarcinoma" (pathologist does not state that it is "arising in a sessile polyp")?
Discussion:
Answer:
For tumors diagnosed prior to 2007:
Code the Histology field to 8210/3 [adenocarcinoma arising in a polyp]. The structure in which this adenocarcinoma is arising, is a polyp.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
