Question:
Histology (Pre-2007)--Colon: What code is used to represent the histology "adenocarcinoma arising in a papillary adenomatous polyp"? See discussion.
Discussion:
Is "adenocarcinoma arising in a papillary adenomatous polyp" equivalent to adenocarcinoma in a villous adenoma [8261/3] or adenocarcinoma in an adenomatous polyp [8210/3]?
Answer:
For tumors diagnosed prior to 2007:
Code the Histology field to 8261/3 [adenocarcinoma in a villous adenoma]. In describing colon polyps, papillary and villous are equivalent terms.
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.
