Question: How should I code an extravesical ureteroneocystostomy the urologist performed laparoscopically with robotic assistance? Minnesota Subscriber Answer: First, determine whether the urologist performed a cystoscopy and placed a ureteral stent during the encounter. Then report either 50947 (Laparoscopy, surgical; ureteroneocystostomy with cystoscopy and ureteral stent placement) or 50948 (... ureteroneocystostomy without cystoscopy and ureteral stent placement), depending on the answer to that question. The robotic assistance, HCPCS code S2900 (Surgical techniques requiring use of robotic surgical system (list separately in addition to code for primary procedure)), is included in either code and, therefore, not reported separately.
