About 75831: Unilateral renal vein venography
Report unilateral renal venography for fluoroscopic contrast imaging of one kidney’s venous drainage, such as when evaluating suspected renal vein obstruction or abnormality.
This service is fluoroscopic imaging of one side’s renal veins after contrast is introduced into the venous system, commonly through a catheter. A radiologist or interventional radiologist supervises the imaging and interprets the resulting study, often in a hospital or outpatient imaging setting. The examination can document renal venous anatomy and patency when a clinician is investigating a suspected obstruction or other venous abnormality.
Select this code for a unilateral renal-vein study; use the bilateral renal-vein code when both sides are imaged. The report should identify the side examined and support that renal venography was performed, with the images and interpretation documenting the findings. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff; without either modifier, the claim represents the global service. CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component.

75831 billing questions
When should this code be chosen instead of 75833?
Use 75831 for imaging of one side’s renal veins. Use 75833 when the study images both sides.
Can the professional and technical services be billed separately?
Yes. Modifier 26 reports the professional interpretation, and modifier TC reports the technical service. Billing without either modifier represents the global service.
Does the multiple procedure reduction affect both components?
CMS applies the cardiovascular diagnostic multiple procedure reduction to the technical component.
What documentation supports unilateral reporting?
Document the side examined and include the venographic images and interpretation supporting the renal-vein study.
Is catheter placement included in this code?
This code represents the renal venography imaging service and its supervision and interpretation. Report a separately performed catheter placement service only when supported by the procedure documentation and applicable coding rules.
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.
