Summary & Overview
HCPCS C7528: Coronary Angiography with Intravascular Flow Reserve Measurement
HCPCS Level II code C7528 represents a comprehensive coronary angiography procedure that includes catheter placement in the coronary arteries, right and left heart catheterization, left ventriculography when performed, and intravascular Doppler velocity and/or pressure-derived coronary flow reserve measurement for the initial vessel or graft, including pharmacologic stress. This code captures advanced physiologic assessment during invasive coronary angiography and is important for accurate reporting of combined imaging and hemodynamic measurement services. Nationally, precise coding of such procedures affects coverage determinations, quality measurement, and aggregate utilization tracking for complex coronary diagnostics.
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 clinical service tied to the code, benchmarks and utilization context where available, common modifiers and service-line considerations, and implications for billing and policy alignment. The publication also outlines typical sites of service and the clinical scenarios in which intravascular physiologic measurements are performed. Data not available in the input is noted where applicable. This summary is intended for revenue cycle, coding, and clinical leadership seeking a national perspective on reporting and contextualizing advanced coronary angiography with physiologic assessment.
Billing Code Overview
HCPCS Level II code C7528 describes catheter placement in coronary artery(ies) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation. The service also includes right and left heart catheterization with intraprocedural injection(s) for left ventriculography when performed, and intravascular Doppler velocity and/or pressure-derived coronary flow reserve measurement for the initial coronary vessel or graft during coronary angiography, including pharmacologically induced stress.
Service Type: Diagnostic and invasive cardiovascular catheterization with physiologic coronary flow assessment
Typical Site of Service: Hospital catheterization laboratory (inpatient or outpatient) or ambulatory surgical center with interventional cardiology capability
Clinical & Coding Specifications
Clinical Context
A 64-year-old male with a history of hypertension and hyperlipidemia presents to the hospital with exertional chest pain and an abnormal stress test. Coronary angiography with hemodynamic assessment is scheduled. In the catheterization laboratory, arterial and venous access are obtained; selective right and left coronary artery catheterization is performed with intraprocedural contrast injections for coronary angiography. Right and left heart catheterization is completed, including left ventriculography when indicated. Intravascular Doppler velocity and/or pressure-derived coronary flow reserve (CFR) measurement is performed in the initial coronary vessel during pharmacologically induced stress to assess physiologic significance of intermediate coronary lesions. Imaging supervision and interpretation are documented by the interventional cardiologist. The typical site of service is an outpatient or inpatient hospital catheterization laboratory or ambulatory surgical center equipped for invasive coronary diagnostic procedures. Typical patient workflow includes pre-procedure consent and assessment, vascular access and angiographic imaging, physiologic measurements (CFR/FFR), possible left ventriculography, recovery monitoring, and discharge or admission based on findings and comorbidities.
