Urology
About 50686: Ureteral pressure-flow study
Report this study when a urologist perfuses the upper urinary tract and measures pressure to assess whether suspected ureteral obstruction is functionally significant.
This pressure-flow study, commonly called a Whitaker test, evaluates suspected obstruction in the upper urinary tract, including an equivocal blockage near the ureteropelvic junction. A urologist infuses fluid through access to the renal collecting system while measuring pressure, often comparing renal-pelvic pressure with bladder pressure. It is typically performed in a procedural or radiology setting when imaging alone has not clarified whether hydronephrosis reflects meaningful obstruction.
Report the study for the pressure measurement and perfusion service, supported by documentation of the access used, fluid perfusion, pressure readings, and clinical question being evaluated. CMS assigns 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 is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
CMS billing rules for 50686
- Global period
- Minor procedure with a 0-day global period: same-day preoperative and postoperative care is included.
- Multiple procedures
- Standard multiple procedure reduction: the highest-valued procedure is paid in full and others at 50% when performed in the same session.
- Bilateral procedures
- Bilateral adjustment does not apply; the descriptor or anatomy makes modifier 50 inappropriate.
- Assistant at surgery
- Assistant at surgery is paid only with documentation of medical necessity.
- Co-surgeons

50686 compared with similar codes
Office rates for Nevada, from the same CMS release.
50690 describes antegrade contrast imaging of the collecting system or ureter. Code 50686 is for pressure-flow testing, not an imaging injection alone.
50600 describes operative exploration of the ureter. Code 50686 assesses upper-tract pressure during perfusion rather than surgically exploring the ureter.

50686 billing questions
How is this different from ureterography codes 50684 and 50690?
50686 measures pressure during fluid perfusion to assess functional obstruction. Codes 50684 and 50690 describe contrast-injection imaging procedures.
When is a Whitaker test considered?
It may be used when hydronephrosis or suspected upper-tract obstruction remains functionally uncertain after other evaluation. The documented purpose should be pressure-flow assessment, not simply anatomic imaging.
Should modifier 50 be appended for testing both sides?
No. CMS identifies modifier 50 as inappropriate for this code.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's global period.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
