In the context of coding for cystourethroscopy involving the removal of bladder tumors, the appropriate coding practice entails that only the largest tumor should be coded. This is based on the National Correct Coding Initiative (NCCI) guidelines, which stipulate that for procedures that are performed in an anatomical structure where multiple lesions or tumors are treated during the same session, only the primary procedure or the procedure performed on the largest lesion is reported.

By this rule, the rationale is to avoid duplication of coding for procedures that represent the same anatomical manipulation or for similar services rendered at one time. It also simplifies the documentation and billing process by consolidating treatments into the most significant code.

While the other options suggest various approaches that may seem plausible, they do not align with the prevalent coding conventions for this specific scenario. For example, using multiple CPT codes with modifiers or separately coding for each tumor might not accurately reflect the coding principles intended to streamline and clarify billing practices. Thus, focusing on coding for just the largest tumor ensures consistency with accepted coding guidelines.
