What 75600 covers

This service covers contrast imaging of the thoracic aorta and the physician’s radiological supervision and interpretation. It may be performed in a hospital angiography suite or an outpatient catheterization setting to evaluate the aorta’s anatomy or suspected disease, such as an aneurysm or dissection. The defining distinction from the related serial-imaging code is that this examination is performed without serialography. A radiologist or another qualified physician interprets the images.

Choose the code based on the imaging performed, not simply the suspected diagnosis. The report should identify the thoracic aortic coverage, describe the contrast examination and findings, and support that serial imaging was not performed. Report modifier 26 for the professional interpretation or TC for the technical service; reporting without either modifier represents the global service. When multiple cardiovascular diagnostic procedures are reported, the multiple-procedure reduction applies to this code’s technical component. Catheter placement is distinct from the imaging interpretation and may be separately reported when appropriate.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

75600 billing questions

When should this code be chosen instead of 75605?

Use 75600 when the thoracic aortic contrast examination is performed without serialography. Use 75605 when serial radiographic imaging is performed.

Can the professional and technical portions be billed separately?

Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.

Does this code include aortic catheter placement?

The code represents the thoracic aortic imaging supervision and interpretation, not catheter placement itself. Report catheter placement separately when appropriate to the procedure.

What documentation supports reporting 75600?

Document the thoracic aortic coverage, the contrast examination, the interpretation and findings, and that the study was performed without serialography.

How does the multiple-procedure reduction affect this service?

When multiple cardiovascular diagnostic procedures are reported, the reduction applies to the technical component of 75600.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
