CPT code 74400: Urography, intravenous contrast2026 Medicare rate & RVUs

Medicare pays $131.93 for 74400 nationally in the office. Local office rates run $115.02–$183.41.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.

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.
