Billing code 75733: Adrenal angiographyMedicare rate & RVUs

Medicare pays $175.02 for 75733 nationally in the office. Local office rates run $155.45–$235.76.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 75733 covers

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.

75731 is for a unilateral adrenal arterial study; 75733 represents bilateral evaluation and is already priced as bilateral.

75726Visceral angiography

75726 addresses abdominal arterial imaging more broadly. Choose 75733 for a focused study of both adrenal arterial supplies.

75774Arterial imaging

75774 describes qualifying additional selective vessel imaging after a basic examination; it is not the code for the bilateral adrenal study itself.
