Question: Would a barbotage urine sample done at the same time as cystoscopy ever be coded separately? The documentation states “a barbotage urine sample was obtained and sent for cytology. The cystoscope was removed.” Washington, D.C., Subscriber Answer: The ““barbotage technique” refers to a method of bladder washing used to obtain the urine sample. You can report codes for both procedures: 52000 (Cystourethroscopy (separate procedure)) and 51700 (Bladder irrigation, simple, lavage and/or instillation). Append modifier 59 (Distinct procedural service) to 51700 and include documentation explaining why you are reporting both codes instead of only 52000.
