Summary & Overview
HCPCS C7518: Coronary and Bypass Graft Angiography with IVUS/OCT
HCPCS Level II code C7518 represents combined coronary and bypass graft catheterization for angiography with endoluminal imaging using intravascular ultrasound (IVUS) or optical coherence tomography (OCT), including imaging supervision, interpretation, and reporting. This code captures procedures that integrate diagnostic angiography of native coronary arteries and bypass grafts with advanced intravascular imaging, relevant to centers performing complex coronary evaluations and interventions. Nationally, the code matters because it distinguishes integrated intraprocedural imaging services from standard angiography, which can affect documentation, coding accuracy, and payer coverage determinations.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical and procedural scope of the code, the expected service setting, and the payer landscape considered. The publication provides benchmarks and coding context where available, notes common billing modifiers encountered with complex interventional procedures, and summarizes clinical circumstances in which intravascular imaging is used during diagnostic evaluation and therapeutic intervention. Data not available in the input is noted as such in relevant sections.
Billing Code Overview
HCPCS Level II code C7518 describes catheter placement in coronary artery(ies) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation, with catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) including intraprocedural injection(s) for bypass graft angiography with endoluminal imaging of initial coronary vessel or graft using intravascular ultrasound (ivus) or optical coherence tomography (oct) during diagnostic evaluation and/or therapeutic intervention including imaging, supervision, interpretation and report.
-
Service type: Diagnostic and interventional coronary angiography with intraluminal imaging (intravascular ultrasound or optical coherence tomography), including catheter placement in native coronary arteries and bypass grafts, and imaging supervision and interpretation.
-
Typical site of service: Hospital-based or ambulatory surgical settings where invasive coronary angiography and intravascular imaging are performed, such as cardiac catheterization laboratories and tertiary care centers.
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of prior coronary artery bypass grafting (CABG), hypertension, hyperlipidemia, and recurrent exertional angina presents to the cardiac catheterization lab for diagnostic coronary angiography with intravascular imaging. The patient reports worsening chest pain despite medical therapy and noninvasive testing suggesting ischemia in the distribution of a prior graft. After informed consent, the patient is taken to the catheterization suite where vascular access is obtained (typically via the femoral or radial artery). A coronary catheter is advanced into the native coronary arteries and known bypass grafts (internal mammary and saphenous vein grafts). Contrast injections are performed for diagnostic angiography of native coronaries and grafts. During the procedure, intravascular ultrasound (IVUS) or optical coherence tomography (OCT) is performed in an initial target vessel or graft to characterize lesion morphology and guide potential therapeutic intervention (eg, percutaneous coronary intervention). Imaging supervision, interpretation, and a formal report are completed by the attending interventional cardiologist. Typical sites of service include hospital cardiac catheterization labs and ambulatory surgical centers equipped for cardiac catheterization. Procedural documentation includes vascular access site, catheters used, grafts catheterized, number of injections, IVUS/OCT images obtained, findings, and any adjunctive therapeutic procedures performed during the same session.
