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.
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.

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.
