CPT code 75565: Cardiac MRI, velocity flow mapping2026 Medicare rate & RVUs in California

Medicare pays $48.97–$62.54 for 75565 in the office in California, from Chico, CA to San Benito County, CA. 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 75565 covers

This add-on captures and analyzes blood-flow velocity during cardiac MRI, such as flow across a valve or through a vessel. It can help quantify regurgitant flow or assess a suspected shunt, including in congenital heart disease. An MRI technologist performs the acquisition, with interpretation by a radiologist or cardiologist. The service is used with a primary cardiac MRI examination, not as a stand-alone study.

Report 75565 only when velocity flow mapping is performed in addition to the primary cardiac MRI; the record should support the mapping acquisition and its interpretation. CMS treats it as an add-on paid within the primary procedure's global period. The diagnostic test has professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and reporting without either modifier represents the global service.

How to choose

75557Cardiac MRIMorphology and function, no contrast

75557 identifies the primary cardiac MRI without stress imaging or contrast. Add 75565 only when velocity flow mapping is also performed.

75561Cardiac MRIMorphology and function with contrast

75561 identifies a primary cardiac MRI with contrast and without stress imaging. It does not, by itself, identify velocity flow mapping.

75563Cardiac MRIStress imaging with contrast

75563 identifies a primary cardiac MRI with stress imaging and contrast. 75565 is a separate add-on when velocity flow mapping is performed with that examination.

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.
