Question:

Histology (Pre-2007)--Bladder: What is the correct histology code for this tumor of the bladder? See Discussion.

Discussion:

TURBT was performed with invasive residual tumor remaining - path report reads "Mixed carcinoma of the urinary bladder, with components of invasive high grade urothelial carcinoma, invading deep muscle, and small cell carcinoma."

Answer:

For tumors diagnosed prior to 2007:

Code combined small cell carcinoma [8045]. This mixed carcinoma is both urothelial and small cell. It is important to capture the small cell information in the code because the prognosis for small cell is different from pure urothelial 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.
