CPT code 75731: Adrenal angiography, unilateral2026 Medicare rate & RVUs in California

Medicare pays $160.67–$202.37 for 75731 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

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

What 75731 covers

This study uses catheter-delivered contrast and X-ray imaging to show arterial supply to one adrenal gland. An interventional radiologist or other physician qualified to perform angiography typically conducts it in a hospital angiography suite. The study may be used when clinicians need to assess an adrenal arterial abnormality, vascular anatomy, or a suspected source of bleeding; it describes diagnostic imaging, not treatment of the vessel.

Report 75731 for the unilateral study; use 75733 when both adrenal sides are imaged. The record should identify the side examined, catheter position and contrast imaging performed, and include the physician’s interpretation and clinical indication. The code has professional and technical components: report modifier 26 for interpretation, TC for equipment and staff, or neither for the global service. When multiple cardiovascular diagnostic procedures are performed, the CMS multiple-procedure reduction applies to the technical component.
