Summary & Overview
HCPCS C7520: Coronary and Bypass Graft Angiography with Pelvic Arterial Imaging
HCPCS Level II code C7520 represents catheter placement for coronary angiography that explicitly includes catheterization of bypass grafts and concurrent non-selective iliac and/or femoral artery angiography. The code bundles intraprocedural injections, image production, and radiologic supervision and interpretation associated with comprehensive coronary and graft angiographic evaluation. Nationally, this code matters because it captures combined cardiac and peripheral pelvic arterial imaging performed during cardiac catheterization, which affects billing classification and payment pathways for cardiovascular and interventional radiology services.
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 and procedural context for C7520, payer coverage considerations, common billing modifiers, and where this code fits within cardiac catheterization service lines. The publication outlines benchmark considerations, documentation elements tied to the bundled procedure, and typical sites of service where C7520 is reported. Data not available in the input is noted where applicable, including specific associated taxonomies, ICD-10 diagnoses, and related procedure codes.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with exertional chest pain and known history of prior coronary artery bypass grafting (CABG) presents for diagnostic coronary angiography to evaluate for graft patency and native coronary disease. Vascular access is obtained via the right femoral artery. A guiding catheter is advanced into the aortic root and selective catheterization of the native coronary arteries is performed for coronary angiography. Because the patient has prior CABG, catheter placements are also performed in one or more bypass grafts (internal mammary artery graft, saphenous vein graft) to obtain graft angiography. At the same session, non-selective iliac and/or femoral angiography is performed through catheter positioning in the distal aorta or ipsilateral iliac/femoral artery to assess peripheral access anatomy. Intraprocedural injections of iodinated contrast are given for coronary and graft imaging, permanent digital images are produced, and radiologic supervision and interpretation are completed. Typical workflow steps: pre-procedure consent and review, arterial access and sheath placement, catheter selection and placement in coronary arteries and bypass grafts, contrast injections with fluoroscopic imaging, acquisition of diagnostic images, hemostasis and sheath removal, and post-procedure monitoring in recovery.
