Question:

First Course Cancer-Directed Treatment--Bladder: How should Mitomycin-C instillation for bladder cancer be coded?

Discussion:

Answer:

Code the instillation of Mitomycin-C into the bladder for a bladder primary in both the Chemotherapy and Surgery to Primary Site fields. Code the Chemotherapy field to 02 [Single-agent chemotherapy administered as first course therapy]. Mitomycin-C is listed in SEER book 8 as a chemotherapeutic drug, specifically an alkylating agent.

Also, code the Surgery of Primary Site field to 15 [intravesical therapy]. Code the surgical procedure as well as the type of drug (chemotherapy in this case).
