Question:

Histology (Pre-2007): Can adenocarcinoma in either a villous or tubulovillous polyp or adenoma be coded as histology for sites other than colon or rectum? See discussion.

Discussion:

When adenocarcinoma of the endometrium arises in a villoglandular polyp is the histology coded as 8263/3?

Answer:

For tumors diagnosed prior to 2007:

Code the Histology field to 8263/3 [adenocarcinoma in a tubulovillous adenoma]. Histology codes 8261 [adenocarcinoma in a villous adenoma] and 8263 [adenocarcinoma in a tubulovillous adenoma] are used for non-colorectal sites when the cancer arises in 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.
