Question:

Histology (Pre-2007)--Bladder: What code is used to represent the histology "transitional cell and small cell carcinoma" of the bladder? See discussion.

Discussion:

Code 8045/3 is used for combination codes that represent a mixture of small cell carcinoma and any other carcinoma. When we use this histology code for bladder primaries with mixed transitional cell and small cell carcinoma, we encounter a problem with the SEER edits (site and morphology conflict).

Answer:

For tumors diagnosed prior to 2007:

Please see SEER Inquiry question ID number 20041104.

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.

History:

Code the Histology field to 8120/3 [transitional cell carcinoma] for this case. Refer to the Coding Complex Morphology Diagnoses document. Notice that transitional cell carcinoma is not part of the range of epithelial and glandular carcinomas that combine with small cell carcinoma to form a mixture that is coded to 8045/3.
