Summary & Overview
HCPCS C7522: Coronary Angiography with CFR and Right Heart Catheterization
HCPCS Level II code C7522 represents a complex diagnostic and physiologic coronary procedure: catheter placement for coronary angiography with right heart catheterization and intravascular Doppler or pressure-derived coronary flow reserve (CFR) measurement during pharmacologic stress. This code captures both imaging and advanced physiologic assessment integral to contemporary ischemia evaluation and revascularization planning. Nationally, the use of such advanced physiologic measurements informs clinical decisions and affects facility and professional billing patterns due to its combined diagnostic and interpretive components.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the service captured by C7522, discussion of common billing considerations and modifiers, and context on where the procedure is typically performed. The publication summarizes expected service lines and clinical context for cardiology and interventional cardiology teams, outlines payer relevance, and highlights where benchmarks or coverage policies can influence utilization. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code C7522 describes catheter placement in coronary artery(ies) for coronary angiography with intraprocedural injections, imaging supervision and interpretation, and right heart catheterization. The procedure includes intravascular Doppler velocity and/or pressure-derived coronary flow reserve measurement for the initial coronary vessel or graft and is performed during coronary angiography with pharmacologically induced stress.
Service Type: Diagnostic coronary angiography with advanced physiologic assessment (coronary flow reserve) and right heart catheterization.
Typical Site of Service: Cardiac catheterization laboratory or interventional cardiology suite in an acute care hospital or outpatient cardiac catheterization center.
Clinical & Coding Specifications
Clinical Context
A 64-year-old male with progressive exertional angina and a history of prior coronary artery bypass grafting presents for invasive coronary assessment. Noninvasive testing (stress imaging) demonstrated reversible ischemia in the distribution of the left anterior descending territory. Coronary angiography with right heart catheterization is scheduled to evaluate native coronary arteries and graft patency, measure intracoronary pressure and flow reserve, and perform pharmacologic vasodilator stress to assess physiological significance of lesions.
Pre-procedure workflow includes informed consent, review of anticoagulation and renal function, and periprocedural medication planning (antiplatelet and vasodilator agents). Vascular access is obtained (femoral or radial), coronary catheters are advanced to the coronary ostia for angiographic injections, and simultaneous right heart catheterization is performed. Intravascular Doppler velocity and/or pressure-derived coronary flow reserve (CFR) measurements are obtained in the initial coronary vessel or graft, with pharmacologically induced hyperemia (for example, intravenous or intracoronary adenosine). Imaging supervision and interpretation are performed by the interventional cardiologist, with hemodynamic data recorded for diagnostic and treatment planning purposes. Post-procedure monitoring includes access site assessment, hemodynamic observation, and discharge planning or admission based on findings and patient stability.
