CPT code 75573: Cardiac CT, congenital heart disease2026 Medicare rate & RVUs

Medicare pays $309.29 for 75573 nationally in the office. Local office rates run $275.46–$413.24.

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

What 75573 covers

This examination uses contrast-enhanced computed tomography to map cardiac structures in congenital heart disease. It can show chamber connections, great vessels, and venous anatomy, with three-dimensional image processing and functional assessment when performed. Radiologists commonly interpret the study in coordination with congenital cardiologists or cardiac surgeons. It may be used to define anatomy in a patient with a known or suspected congenital defect or to support procedural planning when detailed cross-sectional imaging is needed.

Choose this code for a congenital heart disease evaluation, rather than a general cardiac morphology study or a coronary-focused CT angiogram. The report should establish the congenital indication and document the structures assessed and interpretation; the imaging record should support the contrast-enhanced cardiac study. CMS recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or neither for the global service. The diagnostic imaging multiple procedure reduction applies to both the technical and professional components.

How to choose

75572Cardiac CTStructure and morphology

75573 is selected for a congenital heart disease evaluation. 75572 covers contrast-enhanced cardiac morphology imaging without that congenital focus.

75574Coronary CTAWith contrast and 3D reconstruction

75574 is coronary CT angiography, while 75573 evaluates congenital cardiac anatomy. The intended structures and imaging protocol distinguish them.

75561Cardiac MRIMorphology and function with contrast

75561 uses MRI with contrast for cardiac morphology; 75573 uses CT with contrast for congenital heart disease evaluation.

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.
