What 75559 covers
This study uses magnetic resonance imaging to assess cardiac structure and function during stress, without contrast material. It is typically performed in a hospital imaging department by MRI staff, with a radiologist or cardiologist interpreting the images. Stress imaging may be used to evaluate how the heart responds to stress when assessing suspected ischemia or other cardiac concerns.
Select this code when the cardiac MRI includes stress imaging and no contrast is administered; a stress study performed with contrast is represented by 75563. The record should support the cardiac MRI protocol, stress imaging, absence of contrast, and the interpreting provider’s findings. The service has professional and technical components: report modifier 26 for interpretation only, modifier TC for equipment and staff only, or no component modifier when billing the global service. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components when applicable.

How to choose
- 75557Cardiac MRIMorphology and function, no contrast
- Use 75557 for cardiac MRI without contrast when stress imaging is not performed. Use 75559 when the study includes stress imaging.
- 75561Cardiac MRIMorphology and function with contrast
- 75561 describes cardiac MRI with contrast but without stress imaging. The stress component distinguishes 75559, which is performed without contrast.
- 75563Cardiac MRIStress imaging with contrast
- Both codes include cardiac MRI stress imaging; contrast use separates them. Report 75563 when contrast is used and 75559 when it is not.
75559 billing questions
How does 75559 differ from 75563?
Both describe cardiac MRI with stress imaging. Use 75559 when the study is performed without contrast and 75563 when contrast is used.
When should 75557 be reported instead?
75557 represents cardiac MRI for morphology and function without stress imaging. Report 75559 when the study also includes stress imaging.
Can the professional and technical portions be billed separately?
Yes. Use modifier 26 for the interpretation and modifier TC for the technical service. Without either modifier, the claim represents the global service.
Does CMS reduce payment when multiple diagnostic imaging services are performed?
The diagnostic imaging multiple procedure reduction applies to both the technical and professional components of this code when applicable.
What documentation supports reporting 75559?
Document the cardiac MRI protocol, that stress imaging was performed, that contrast was not used, and the interpretation of the study.
Can cardiac MRI flow mapping be reported with 75559?
Code 75565 is an add-on for cardiac MRI velocity flow mapping and may be reported with 75559 when that mapping service is performed and documented.
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.
