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

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.
