Question:

Histology (Pre-2007): What code is used to represent the histology "PD infiltrating duct ca with focal sarcomatoid pleomorphic features?"

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code histology as 8500/33 [Infiltrating duct carcinoma, poorly differentiated]. "Features" is a term from the list indicating a majority of the tumor, however; in this case "features" is modified by "focal" which does not indicate a majority of the tumor.

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.
