What 75557 covers

This service uses magnetic resonance imaging to assess cardiac anatomy and function without contrast material. A cardiac radiologist or other qualified interpreting physician reviews images of the chambers, myocardium, and related structures; the study may be performed in a hospital or outpatient imaging center. Clinical indications can include evaluation of cardiomyopathy, ventricular function, or congenital cardiac anatomy when a noncontrast protocol is appropriate.

Select 75557 for a noncontrast, nonstress cardiac MRI; a study that uses contrast or stress imaging belongs to a different code in the cardiac MRI family. The report should support the protocol performed and the structural or functional findings assessed. Billing without a modifier represents the global service; modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff portion. When multiple diagnostic imaging services are subject to the multiple procedure reduction, it applies to both the technical and professional components.
