What 50690 covers
A urologist injects contrast through a ureteral catheter to outline the ureter and, when needed, the renal collecting system on X-ray. The injection may be performed during an operative or endoscopic encounter to assess anatomy or investigate a suspected narrowing, obstruction, or filling defect. This code represents the injection procedure, not the radiologist’s interpretation of the images.
Select 50690 when the documented service is injection through a ureteral catheter for retrograde ureterography or ureteropyelography. The record should identify the access route, contrast injection, and study performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

- 52005Ureteral catheterization
- 52005 describes cystourethroscopy with ureteral catheterization and may include instillation or ureteropyelography. 50690 describes the injection procedure through a ureteral catheter, not the cystoscopic catheterization service.
- 74420Retrograde urography
- 74420 covers radiological supervision and interpretation of retrograde urography; 50690 covers the contrast injection procedure.
50690 billing questions
How does 50690 differ from 50684?
50690 describes contrast injection through a ureteral catheter for a retrograde study. 50684 is for an antegrade nephrostogram or ureterogram through existing access.
Does 50690 include the image interpretation?
No. 50690 represents the injection procedure; 74420 describes radiological supervision and interpretation for retrograde urography when that service is performed and documented.
Can 50690 be reported with 52005?
52005 describes cystourethroscopy with ureteral catheterization and may include instillation or ureteropyelography. Do not use 50690 as a substitute for that cystoscopic service or separately report the same work without support for distinct services.
Can modifier 50 be used when both ureters are studied?
No. CMS identifies bilateral adjustment as inapplicable to 50690, so modifier 50 is not appropriate.
How does the multiple-procedure reduction affect 50690?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard 50% reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
