What 50684 covers
A urologist injects contrast through a catheter positioned in the ureter to outline the ureter and, when needed, the renal pelvis on imaging. This retrograde study can help assess the collecting system during cystoscopy or another urologic procedure, such as evaluation of a suspected narrowing, obstruction, or filling defect. The code represents the injection service; imaging supervision and interpretation may be represented separately when supported and reported under the applicable imaging code.
Documentation should identify the catheter route, the side examined, the contrast injection, and the clinical purpose. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral reporting with modifier 50, CMS pays 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.
