CPT code 75561: Cardiac MRI, morphology and function with contrast2026 Medicare rate & RVUs in Louisiana

Medicare pays $333.21–$349.52 for 75561 in the office in Louisiana, from Rest of Louisiana to New Orleans, LA. Which amount applies depends on the service address.

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

What 75561 covers

This cardiac MRI evaluates heart structure and function using images acquired before and after intravenous contrast, without stress imaging. It can assess ventricular size and performance, chamber anatomy, myocardium, and cardiac masses; contrast-enhanced tissue assessment may help evaluate conditions such as cardiomyopathy, myocarditis, scar, or selected congenital abnormalities. A technologist performs the scan in a hospital or outpatient imaging facility, and a radiologist or cardiologist interprets the study.

Report 75561 when the performed protocol includes contrast-enhanced morphology and function imaging without a stress component. Documentation should identify the clinical indication, contrast administration, imaging performed, and findings supporting the structural and functional assessment. Medicare recognizes professional and technical components: use modifier 26 for the interpretation, modifier TC for equipment and staff, or neither modifier when billing the global service. When multiple diagnostic imaging procedures are performed, the diagnostic imaging multiple-procedure reduction applies to both the professional and technical components.

How to choose

75557Cardiac MRIMorphology and function, no contrast

75557 describes cardiac morphology and function imaging without contrast. Use 75561 when the performed study includes contrast-enhanced imaging.

75559Cardiac MRIStress imaging, no contrast

75559 includes stress imaging but not contrast. 75561 is the contrast-enhanced morphology and function study without stress imaging.

75563Cardiac MRIStress imaging with contrast

75563 includes both stress imaging and contrast. Choose 75561 when contrast is used but the cardiac MRI does not include stress imaging.

75565Cardiac MRIVelocity flow mapping

75565 covers additional cardiac MRI velocity flow mapping and is an add-on, not a substitute for the primary morphology and function study.

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.
