CPT code 75605: Thoracic aortography, serial image acquisition2026 Medicare rate & RVUs

Medicare pays $120.91 for 75605 nationally in the office. Local office rates run $107.48–$157.81.

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

What 75605 covers

This service covers the physician’s supervision and interpretation of serial images obtained as contrast passes through the thoracic aorta. It may be used to assess aortic anatomy when evaluating suspected aneurysm, dissection, coarctation, or narrowing. A radiologist, cardiologist, vascular surgeon, or another qualified physician may interpret the study during a catheter angiography session in a hospital or other imaging setting.

Select this code when the documented thoracic aortography uses serial image acquisition; 75600 is the related thoracic study without serial imaging. The report should identify the imaged aortic segment, describe the imaging performed, and include the physician’s findings and interpretation. Catheter placement and contrast administration may be represented by separate procedure coding when performed and supported. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and billing without either modifier represents the global service. When the cardiovascular diagnostic multiple procedure reduction applies, it affects the technical component.
