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.

75557 billing questions

When should 75557 be chosen instead of 75561?

Use 75557 when the cardiac MRI is performed without contrast. A study that uses contrast is reported with 75561, subject to the protocol actually performed.

How does 75557 differ from 75559?

75557 describes a nonstress cardiac MRI. 75559 is for cardiac MRI with stress imaging, without contrast.

Can 75565 be reported with 75557?

Yes, 75565 is the add-on for cardiac MR velocity-flow mapping when that additional mapping is performed and documented.

Which modifiers identify the MRI components?

Report modifier 26 for the physician's interpretation and modifier TC for the technical portion. Reporting 75557 without either modifier represents the global service.

Do multiple-procedure reductions affect 75557?

The diagnostic imaging multiple procedure reduction applies to the technical and professional components when applicable.

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.
