What 74415 covers
This examination tracks intravenously administered contrast through the kidneys and urinary tract using radiographs, including nephrotomographic images focused on the kidneys. It may be used to assess suspected abnormalities of the renal collecting systems or urinary tract. Imaging staff acquire the study, typically in a hospital radiology department, and a radiologist interprets the images.
Choose this code when the documented examination uses infusion and/or bolus contrast and includes nephrotomography; the contrast method alone is not enough to distinguish it from related urography services. The report and image record should support the urinary tract examination and the nephrotomographic views. CMS allows billing the professional component with modifier 26 for interpretation, the technical component with modifier TC for equipment and staff, or the global service without either modifier.

How to choose
- 74410Intravenous urography
- Use 74415 when nephrotomography is included with the intravenous contrast study. 74410 is the related infusion and/or bolus urography code without nephrotomography.
- 74400Urography
- 74400 is another intravenous urography option, with KUB and/or tomography features. Select 74415 when the documented infusion and/or bolus examination includes nephrotomography.
- 74420Retrograde urography
- 74420 describes retrograde rather than intravenous contrast administration. The contrast route and examination performed separate it from 74415.
74415 billing questions
How does 74415 differ from 74410?
Both describe intravenous urography using infusion and/or bolus contrast. 74415 is the choice when nephrotomography is included; 74410 is the related code without that feature.
What documentation supports reporting 74415?
The imaging record should support the intravenous contrast examination and show that nephrotomographic views of the kidneys were obtained. The interpretation should document the findings from the study.
Can the professional and technical services be billed separately?
Yes. Report modifier 26 for the professional interpretation or modifier TC for the technical service; bill without a modifier for the global service.
Is nephrotomography required for this code?
Yes. The distinguishing feature is nephrotomography as part of the intravenous urography examination.
How does 74415 differ from retrograde urography?
74415 follows contrast given intravenously. Retrograde urography, such as 74420, evaluates the urinary tract with contrast introduced retrograde rather than through an intravenous injection.
