About 75733: Bilateral adrenal arterial angiography
Bilateral adrenal angiography images the arterial supply to both adrenal glands and is reported when a catheter-directed study evaluates both sides.
Bilateral adrenal angiography uses catheter-directed contrast injections and x-ray imaging to show the arterial supply to both adrenal glands. The examination is generally performed in a hospital angiography suite by an interventional radiologist, with the images interpreted by a physician. It may be used when a focused assessment of adrenal arterial anatomy is needed, such as evaluating a suspected vascular abnormality or planning an intervention.
Report 75733 when the documented study evaluates adrenal arteries on both sides; use unilateral sibling 75731 when only one side is studied. The record should identify the vessels selected, contrast injections and image acquisition, and the physician’s interpretation and findings. Billing without a modifier represents the global service; modifier 26 identifies the interpretation and modifier TC identifies the equipment and staff. CMS prices this code as bilateral, so modifier 50 does not increase payment. When multiple cardiovascular diagnostic procedures are reported, the reduction applies to the technical component.

75733 billing questions
When should 75733 be chosen over 75731?
Use 75733 when the documented adrenal arterial study evaluates both sides. Use 75731 when the angiographic study is unilateral.
Should modifier 50 be added for the bilateral study?
No. CMS prices 75733 as bilateral, and modifier 50 does not increase payment.
How do modifiers 26 and TC apply?
Modifier 26 reports the physician’s interpretation, while TC reports the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
Which part of the service is subject to the multiple procedure reduction?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component. It does not reduce the professional component under the CMS rule provided for this code.
What documentation supports reporting 75733?
Document the bilateral adrenal arterial evaluation, selected vessels, contrast injections and acquired images, along with the physician’s interpretation and findings.
