What 75833 covers
This service covers x-ray imaging and physician interpretation of the veins draining both kidneys, usually during a catheter-based diagnostic evaluation. A radiologist or other qualified physician assesses the contrast images for findings such as impaired venous flow, obstruction, or abnormal venous anatomy. It may be performed when renal vein disease is suspected or when venous anatomy must be defined for treatment planning.
Select the bilateral code when both renal venous systems are imaged; the unilateral counterpart is 75831. The record should support the clinical reason for imaging, the bilateral examination, and the physician’s interpretation. The code has professional and technical components: modifier 26 identifies interpretation, modifier TC identifies the equipment and staff service, and no component modifier represents the global service. The technical component is subject to the cardiovascular diagnostic multiple procedure reduction when applicable. The code is priced as bilateral, so modifier 50 does not increase payment.

How to choose
- 75831Renal venographyUnilateral study
- 75831 is for imaging one renal venous system; 75833 is for bilateral renal venography.
- 75825Caval venographyInferior vena cava
- 75825 evaluates the vena cava, not the renal veins. Use it when the imaged target is the vena cava.
- 75840Adrenal venographyUnilateral study
- 75840 evaluates adrenal venous anatomy; 75833 is specific to imaging both renal venous systems.
- 75810Abdominal venographySplenic, portal, or hepatic veins
- 75810 evaluates splenic or hepatic veins, rather than the renal veins covered by 75833.
75833 billing questions
When should 75833 be chosen instead of 75831?
Use 75833 when the study images both renal venous systems. Use 75831 for a unilateral renal venography study.
Can the professional and technical services be billed separately?
Yes. Report modifier 26 for the physician’s interpretation or modifier TC for the technical service. Without either modifier, the claim represents the global service.
Should modifier 50 be added for bilateral imaging?
No. The code is already priced as bilateral, and modifier 50 does not increase payment.
What happens when other cardiovascular diagnostic procedures are performed in the same session?
The cardiovascular diagnostic multiple procedure reduction applies to this code’s technical component. It does not change the professional component.
Does this code include selective catheter placement?
This code represents the imaging supervision and interpretation. A separately reportable catheter placement may be coded when performed and documented; the venography record should identify the imaged renal veins and the physician’s 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 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.
