About 50396: Percutaneous intrarenal pressure measurement
Reports percutaneous measurement of pressure within the renal collecting system, typically during evaluation of suspected urinary outflow obstruction.
This service measures pressure within the kidney’s collecting system by introducing a needle and injecting fluid while pressure is assessed. Urologists and interventional radiologists may perform it during a diagnostic workup for suspected obstruction, such as when evaluating impaired drainage at the ureteropelvic junction. The procedure may include contrast injection, but the defining service is the pressure measurement rather than imaging alone.
Report the code when the documented service is an intrarenal pressure study, not simply renal-pelvis access, drainage, or a contrast study. The record should support the indication, percutaneous technique, pressure measurement, and any contrast used. 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 procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral performance, modifier 50 is paid at 150%. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons and team surgery are not permitted.

50396 billing questions
When should this be reported instead of a nephrostogram?
Report this code for a documented intrarenal pressure measurement. A nephrostogram evaluates the collecting system with contrast imaging; imaging alone does not represent a pressure study.
Does contrast injection by itself support this code?
No. Contrast may be used during the pressure study, but the service must include measurement of intrarenal pressure.
How is bilateral performance reported?
When the procedure is performed bilaterally, report modifier 50. CMS pays the bilateral procedure at 150% under the supplied payment rule.
How does the multiple-procedure reduction affect payment?
For procedures performed in the same session, CMS pays the highest-valued procedure in full and pays other procedures at 50%.
What care is included in the global period?
The 0-day global period includes same-day preoperative and postoperative care.
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 under the supplied CMS rules.
