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.

75605 billing questions
How is this different from 75600?
75605 is selected for thoracic aortography with serial image acquisition. Use 75600 for a thoracic study without serial imaging.
What do modifiers 26 and TC represent?
Modifier 26 reports the physician’s professional supervision and interpretation. Modifier TC reports the technical service, including equipment and staff; billing without either modifier represents the global service.
Is catheter placement included in this code?
The code represents supervision and interpretation of the imaging, not catheter placement. Catheter placement may be reported separately when performed and supported by the documentation.
What documentation supports reporting 75605?
Document the thoracic aortic segment examined, the use of serial image acquisition, and the interpreting physician’s findings and conclusions.
Which part can be affected by the cardiovascular multiple procedure reduction?
The reduction applies to the technical component. It does not reduce the professional component under the CMS rule supplied for this code.
