What 75840 covers
Adrenal venography uses contrast introduced through an intravascular catheter to show adrenal venous drainage under fluoroscopy. The radiologist interprets the images and documents the findings. It may be performed during catheter-based evaluation of suspected endocrine causes of hypertension or adrenal hormone excess, including procedures that involve adrenal vein sampling. The service is typically performed in an interventional radiology or hospital angiography suite.
Choose this code when one adrenal venous system is imaged; bilateral imaging is represented by 75842. Documentation should identify the side and vessels imaged and support the contrast study and interpretation. Report modifier 26 for the professional interpretation, modifier TC for the technical service, or neither when billing the global service. CMS separately prices 26 and TC. The cardiovascular diagnostic multiple procedure reduction applies to the technical component.

75840 vs 75893 vs 75831: Medicare rates
How to choose
- 75893Venous sampling
- 75893 describes venous blood sampling through a catheter, while 75840 covers contrast imaging and interpretation of adrenal veins.
- 75831Renal venography
- 75831 is venography of one kidney's veins. Choose by the venous anatomy imaged, not merely because both studies are renal-region venography.
75840 billing questions
When should 75840 be chosen instead of 75842?
Use 75840 for imaging of one adrenal venous system. Use 75842 when the study images both sides.
Does 75840 include adrenal vein sampling?
It represents contrast imaging and interpretation, not the collection of blood samples. When sampling is performed, 75893 may describe that distinct service if the record supports it.
Which modifiers identify the professional and technical services?
Use modifier 26 for the physician's interpretation and TC for equipment and staff. Without either modifier, the claim represents the global service.
Does the multiple procedure reduction affect both components?
The CMS cardiovascular diagnostic multiple procedure reduction applies to the technical component of 75840.
What documentation supports reporting 75840?
The record should establish unilateral adrenal venous imaging, identify the side and vessels examined, and include the radiologist's interpretation.
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.
