What code(s) should be reported for a cystourethroscopy and removal of a 2.2-cm bladder tumor using a laser knife?

The appropriate code for cystourethroscopy and removal of a 2.2-cm bladder tumor using a laser knife is indeed the one that reflects both the nature of the procedure and the technology employed in its execution. In this case, the removal of a bladder tumor via a cystourethroscopy commonly falls under the scope of codes that specifically describe the excision of bladder tumors.

The code 52235 accurately captures the essential components of the procedure, as it is designated for the cystourethroscopy with the fulguration (or coagulation) of bladder tumors that are less than 3 cm. This procedure includes the use of laser technology for tumor removal, which enhances precision and can be pivotal for minimizing damage to surrounding tissues. Given that the tumor in question measures 2.2 cm, this code is appropriate for the reported treatment.

The other codes listed either do not pertain to tumor removal or address different aspects of cystourethroscopy procedures. Thus, B is the most fitting choice, aligning perfectly with the procedural details provided.
