About 74420: Retrograde urinary tract imaging interpretation
Reports imaging and interpretation of the upper urinary tract after contrast is introduced retrograde, such as during cystoscopic evaluation of the ureters.
Retrograde urography uses radiographic imaging, commonly fluoroscopy, to show the ureters and renal collecting system after contrast is introduced through a ureteral catheter. A urologist may perform the study during cystoscopy, or a radiologist may provide imaging supervision and interpretation. A KUB image may be part of the examination, but is not required for this code.
Report this service for the radiologic study and its interpretation, not for placing the ureteral catheter. The record should support the retrograde contrast study and include the images and an interpretation of the findings. When one billing entity provides the complete service, report the global service without a component modifier. Use modifier 26 for the professional interpretation or modifier TC for the technical service, including equipment and staff, when those portions are billed separately.

74420 billing questions
How is this different from intravenous urography?
This code describes imaging after contrast is introduced retrograde through a ureteral catheter. Intravenous urography uses contrast administered into a vein.
Can it be reported with cystoscopic ureteral catheterization?
Yes. The radiologic imaging and interpretation may be reported with the catheterization service, such as CPT 52005, when both services are performed and documented.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and modifier TC for the technical service. Report without either modifier when billing the global service.
Does a KUB image have to be obtained?
No. A KUB image may be included, but the retrograde study can be reported without one.
What documentation supports the imaging service?
The record should identify the retrograde contrast study and include the images and an interpretation describing the urinary tract findings.
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.
