What 75893 covers

This service covers radiological supervision and interpretation during catheter-based collection of blood from selected veins. Interventional radiologists commonly perform or interpret the imaging in a hospital or other procedural setting. A classic use is selective adrenal vein sampling to compare hormone levels from adrenal drainage with peripheral blood when evaluating suspected hormone-producing adrenal disease. The code represents the imaging service, not the laboratory analysis of the collected specimens.

Report it when the record supports catheter-based venous sampling and includes the relevant imaging supervision and an interpretation. The catheterization for blood collection may be reported separately with 36500 when supported. Submit 26 for the professional interpretation, TC for the technical service, or neither modifier for the global service. The cardiovascular diagnostic multiple procedure reduction applies to the technical component when applicable; it does not reduce the professional component.

How to choose

36500Venous samplingSelective organ blood samples
36500 represents venous catheterization for blood collection. 75893 represents the associated radiological supervision and interpretation, when performed.
75840Adrenal venographyUnilateral study
Use 75840 for adrenal venous imaging. Use 75893 when the service is catheter-based venous blood sampling with radiological supervision and interpretation.
75820Extremity venographyOne arm or leg
75820 is venography of an arm or leg to image venous anatomy; 75893 concerns catheter-based collection of venous blood.

75893 billing questions

How is 75893 different from adrenal venography?

75893 covers imaging supervision and interpretation for venous blood sampling. Adrenal venography, such as 75840, documents the adrenal veins rather than the blood-sampling service.

Can 75893 be reported with 36500?

Yes, the imaging service may be reported with 36500 for venous catheterization for blood sampling when both services are performed and documented.

Which modifier identifies the interpretation?

Append modifier 26 for the professional interpretation or TC for the technical service. 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. It does not apply to the professional component.

What documentation supports reporting 75893?

Document the catheter-based venous sampling procedure, the imaging supervision provided, and the interpretation. For adrenal sampling, the record should identify the relevant sampling sites and the clinical question being evaluated.

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.
