Coding Complex Morph Dx's, 3. Rule 4 (Revised August 2002)

Question:

Histology (Pre-2007)--Breast: What code is used to represent the histology "duct carcinoma, colloid type"? See discussion.

Discussion:

Do we use 8480/3 [colloid carcinoma] or 8523/3 [duct carcinoma] mixed with other types of carcinomas?

Answer:

For tumors diagnosed prior to 2007:

Code the Histology field to 8480/3 [colloid carcinoma] per Rule 4. The lesion is colloid type of ductal carcinoma, not ductal carcinoma mixed with colloid carcinoma.

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.
