Summary & Overview
HCPCS C9733: Non-ophthalmic Fluorescent Vascular Angiography
HCPCS Level II code C9733 represents non-ophthalmic fluorescent vascular angiography, a diagnostic imaging procedure that visualizes blood vessels using fluorescent contrast agents outside ophthalmic applications. This code is relevant nationally for tracking utilization and coverage of specialized vascular imaging performed in outpatient and ambulatory settings. The procedure supports diagnosis and procedural planning for vascular conditions across multiple specialties.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of coverage considerations and payer inclusion, typical sites of service where the procedure is billed, and clinical context for when the imaging modality is used. The publication highlights benchmark elements such as common modifiers used in billing practice, payer lists, and service-line placement. Where specific data fields were not provided in the input, the report notes their absence as "Data not available in the input." The content is intended to inform billing administrators, coding professionals, and policy analysts about the role and classification of C9733 in contemporary billing workflows.
Billing Code Overview
HCPCS Level II code C9733 describes non-ophthalmic fluorescent vascular angiography, a diagnostic imaging service that captures vascular structures using fluorescent contrast outside of ophthalmic (eye) applications. The service type is diagnostic vascular imaging using fluorescent angiographic techniques. The typical site of service is outpatient imaging suites, hospital outpatient departments, or ambulatory surgical centers where vascular imaging is performed.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old male with peripheral vascular disease and intermittent claudication referred for diagnostic vascular imaging to localize lower-extremity arterial stenosis and plan intervention. The vascular lab schedules a non-ophthalmic fluorescent vascular angiography (procedure code C9733) performed in an outpatient vascular/interventional radiology suite or ambulatory surgical center.
The clinical workflow: the patient arrives fasting, an intravenous line is placed, and informed consent is confirmed. The interventional radiologist or vascular surgeon injects an intravenous fluorescent dye (such as indocyanine green) while a trained technologist operates near-infrared or fluorescence-capable imaging equipment. Real-time imaging is recorded to assess arterial inflow, perfusion defects, collateral circulation, and microvascular integrity. The interpreting physician documents findings, uploads stills and cine loops to the medical record, and provides a procedural report describing the vascular territories imaged, contrast used, quantitative timing when applicable, and any immediate complications. The professional component and/or technical component may be reported with appropriate modifiers as required by payer policy. Typical sites of service are an outpatient vascular lab, interventional radiology suite, or ambulatory surgical center.
