Summary & Overview
HCPCS C9763: Cardiac MRI for Morphology and Function with Stress Imaging
HCPCS Level II code C9763 denotes cardiac magnetic resonance imaging for morphology and function with quantification of segmental dysfunction, performed with stress imaging. This advanced cardiac MRI service provides detailed structural and functional assessment of the heart under stress conditions to identify ischemia, viability, and region-specific contractile abnormalities. Nationally, the code captures a high-acuity imaging service that influences diagnostic pathways for suspected coronary artery disease and complex cardiomyopathies.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coverage and reimbursement considerations across major payers, typical sites of service where the procedure is delivered, and clinical context for use of stress cardiac MRI. The publication summarizes common billing modifiers and operational considerations; where payer-specific policies exist, the analysis highlights typical preauthorization and documentation expectations.
The report provides benchmarks for utilization and reimbursement patterns (when available), discusses coding nuances for cardiac MRI stress protocols, and outlines policy updates relevant to advanced cardiac imaging services. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code C9763 describes cardiac magnetic resonance imaging (MRI) for morphology and function with quantification of segmental dysfunction, performed with stress imaging. The service involves MRI-based assessment of cardiac structure and ventricular function, including measurement of regional wall motion and segmental performance under pharmacologic or exercise-induced stress.
Service Type: Cardiac magnetic resonance imaging with stress imaging, functional and morphological assessment
Typical Site of Service: Hospital outpatient imaging centers or ambulatory imaging centers equipped for cardiac MRI and stress protocols
Clinical & Coding Specifications
Clinical Context
A 62-year-old male with known ischemic cardiomyopathy and exertional angina is referred for cardiac magnetic resonance imaging with pharmacologic stress to evaluate myocardial viability and ischemia. The patient arrives to the outpatient cardiovascular imaging center after fasting for four hours. Pre-scan screening confirms no contraindications to MRI (no incompatible implants, adequate renal function for gadolinium) and recent beta-blocker avoidance per protocol. An IV line is placed for contrast and stress agent administration. Baseline cine sequences are obtained to assess cardiac morphology and global and segmental function. Pharmacologic stress (adenosine or regadenoson) is administered while perfusion and delayed enhancement sequences are acquired to detect stress-induced ischemia and quantify segmental dysfunction. The technologist documents sequence start and end times; the interpreting cardiologist or radiologist reviews images, measures left ventricular volumes, ejection fraction, and regional wall motion, and documents quantitative segmental dysfunction. Final report includes findings on morphology, function, perfusion under stress, and late gadolinium enhancement to assess scar versus inducible ischemia. Typical post-procedure workflow includes monitoring for adverse reactions, medication reversal as needed, and communication of results to the referring cardiologist or primary care provider.
