Coding Complex Morph Dx's, 3. Revised August 2002

Question:

Histology (Pre-2007)--Breast: What code is used to represent the histology "invasive ductal carcinoma, mucinous type and invasive lobular carcinoma"?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code the Histology field to 8522/3 [infiltrating duct and lobular carcinoma] per rule 1 of the Coding Complex Morphologic Diagnoses, because the tumor is both lobular and ductal.

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.
