What 74400 covers
This study, commonly called an intravenous urogram or IVP, follows contrast as the kidneys filter it into the collecting systems and ureters. A radiology team obtains images of the urinary tract, sometimes including a kidney-ureter-bladder view or tomographic images. Urologists and other clinicians may request it to evaluate findings such as hematuria, suspected urinary obstruction, or structural abnormalities. A radiologist interprets the images and documents the findings.
Choose this code for the intravenous excretory approach, rather than an infusion protocol or contrast introduced through a urinary catheter or nephrostomy access. The report should support the route of contrast administration and the imaging performed, including any KUB or tomography. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and billing without either modifier represents the global service.

How to choose
- 74410Intravenous urographyInfusion and/or bolus
- Both describe intravenous urography, but 74410 is for an infusion technique. Select according to the contrast-administration method documented.
- 74415IV urographyWith nephrotomography
- 74415 describes infusion urography with nephrotomography; 74400 is the intravenous excretory study that may include tomography without that infusion protocol.
- 74420Retrograde urographyWith or without KUB
- 74420 is for retrograde urography, with contrast introduced through urinary tract access rather than administered intravenously as for 74400.
- 74425Antegrade urographyNephrostomy-route contrast imaging
- 74425 describes antegrade urography, using contrast introduced through antegrade urinary access instead of intravenous excretion.
74400 billing questions
When is 74400 appropriate instead of an infusion urography code?
Use 74400 for intravenous excretory urography without the infusion technique described by the infusion codes. The documented contrast-administration method guides selection.
What does billing 74400 without a modifier represent?
It represents the global diagnostic service, including the professional interpretation and the technical equipment and staff.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and report; use modifier TC for the technical portion involving equipment and staff.
Can the study include KUB views or tomography?
Yes. The code covers intravenous urography with or without KUB and with or without tomography; the imaging report should identify what was performed.
How does 74400 differ from retrograde or antegrade urography?
74400 follows contrast given intravenously. Retrograde and antegrade studies introduce contrast into the urinary tract through different access routes.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
