2007 MP/H Rules. Colon, (H4)

Question:

MP/H Rules/Histology--Colon: When the microscopic description indicates a colon tumor is "tubulovillous," but the final diagnosis only states "adenocarcinoma," is the histology coded to 8263/3 [adenocarcinoma in a tubulovillous adenoma]?

Discussion:

Answer:

For cases diagnosed 2007 or later:

Yes. This is an example of a site-specific exception to the general rule to code only from the final diagnosis. The Colon Histology Rules specifically state that "other parts of the pathology report" may be used to identify a tumor arising from a polyp, adenomatous polyp, villous adenoma, or tubulovillous adenoma.
