Radiology
About 74425: Antegrade urinary tract contrast study
Reports radiologic imaging and interpretation of the urinary collecting system after contrast is introduced in an antegrade direction through percutaneous access.
Antegrade urography uses radiographic imaging to show the renal collecting system and ureter after contrast is injected through percutaneous urinary access, commonly a nephrostomy catheter. A radiologist or interventional radiologist evaluates how contrast fills and passes through the urinary tract, including in patients being assessed for obstruction, narrowing, or a leak. The service is typically performed in a hospital or imaging department where fluoroscopic equipment and the existing access route are available.
Report 74425 for the antegrade contrast examination and its radiologic supervision and interpretation, rather than for catheter placement or exchange alone. The record should identify the access route, describe contrast flow and the images obtained, and include the interpreting clinician’s findings. CMS recognizes professional and technical components: report modifier 26 for the interpretation, modifier TC for the equipment and staff, or no component modifier when billing the global service. The components are separately priced by CMS.

74425 billing questions
When is 74425 used instead of retrograde urography?
Use 74425 when contrast is introduced in an antegrade direction through percutaneous urinary access, such as a nephrostomy catheter. Retrograde urography uses contrast introduced from the lower urinary tract.
Does 74425 report nephrostomy catheter placement or exchange?
No. It reports the radiologic examination and interpretation of the urinary tract after antegrade contrast injection, not catheter placement or exchange by itself.
How are the professional and technical components reported?
Use modifier 26 for the professional interpretation and modifier TC for the technical service. Billing without either modifier represents the global service.
What documentation supports 74425?
Document the percutaneous access route, contrast injection and resulting images, and the interpreting clinician’s findings about filling and passage through the collecting system and ureter.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
