Question: Alabama Subscriber Answer: You are correct in thinking that you should be reporting 52354 (Cystourethroscopy, with ureteroscopy and/or pyeloscopy; with biopsy and/or fulguration of ureteral or renal pelvic lesion). This is the only code you should be reporting. Report the one CPT code, 52354, for both the biopsy and the laser ablation.
