Question: Is there a specific CPT® code for a diagnostic laparoscopy? The urologist noted recurrent UTI and bladder diverticulum as the diagnoses. Illinois Subscriber Answer: No, the current edition of CPT® does not include a specific code for a diagnostic laparoscopy, performed for the bladder. Therefore, your best option is to report 49320 (Laparoscopy abdomen, peritoneum, and omentum, diagnostic with or without collection of specimen(s) by brushing or washing (separate procedure)) with documentation outlining the urologist’s service. Include diagnoses N39.0 (Urinary tract infection, site not specified) and N32.3 (Diverticulum of bladder).
