Question:

Histology (Pre-2007): What code is used to represent the histology "adenocarcinoma in a tubulovillous adenoma with a mucinous component, the mucinous component is less than 50%"? See discussion.

Discussion:

For mucinous only, the tumor must contain at least 50% mucinous to be coded to the specific histology.

Answer:

For tumors diagnosed prior to 2007:

Code the Histology field to 8263/3 [adenocarcinoma in a tubulovillous adenoma]. Because the mucinous component involves less than 50% of the tumor, the histology is not coded to mucinous. For mucinous only, the tumor must be at least 50% mucinous, mucin producing, to be coded to the specific histology.

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.
