Summary & Overview
CPT 75563: Cardiac MRI Stress and Rest with and without Contrast
CPT code 75563 represents a cardiac magnetic resonance imaging (MRI) examination performed both at rest and under stress, with imaging acquired before and after intravenous contrast to evaluate cardiac morphology and function. This study is clinically important for noninvasive assessment of ischemia, myocardial viability, and structural heart disease when echocardiography or nuclear testing is inconclusive. Nationwide, utilization of cardiac MRI stress studies is growing as MRI provides high-resolution functional and tissue characterization without ionizing radiation.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context and service setting, common billing considerations, and expected site-of-service patterns. The publication summarizes benchmark metrics where available, highlights relevant policy and coverage themes that affect authorization and payment, and outlines typical documentation elements used to support medical necessity. When specific data elements were not provided in the input, the report notes that those items are not available.
This summary is designed for provider billing staff, payer policy analysts, and health system administrators seeking a clear, national-level primer on CPT code 75563, its clinical role, and the administrative considerations affecting access and reimbursement for stress cardiac MRI with and without contrast.
Billing Code Overview
CPT code 75563 describes a cardiac magnetic resonance imaging (MRI) study performed with and without pharmacologic or exercise stress, first acquiring images without intravenous contrast and then with contrast administration to better visualize cardiac morphology and function under stress. The procedure assesses ventricular size, wall motion, perfusion, and other structural features during rest and stress conditions.
Service type: Diagnostic imaging — cardiac MRI with stress, rest and contrast-enhanced sequences
Typical site of service: Outpatient imaging center or hospital radiology/cardiology department
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with known ischemic heart disease and exertional chest pain is referred for a stress cardiac MRI to evaluate myocardial perfusion and ventricular function. The procedure is performed in an outpatient MRI suite at a hospital-based imaging center. The workflow includes pre-procedure screening for MRI safety and renal function, resting cine and perfusion sequences without contrast, administration of a pharmacologic stress agent (e.g., dobutamine or regadenoson) with continuous monitoring, acquisition of stress cine and perfusion images, followed by intravenous gadolinium-based contrast for delayed-enhancement imaging to assess scar and viability. Hemodynamic monitoring and ECG are recorded throughout, and a supervising cardiologist or radiologist interprets images. The report documents wall motion at rest and stress, perfusion defects, ejection fraction, and presence or absence of late gadolinium enhancement to guide revascularization or medical management decisions.
