Summary & Overview
CPT 75774: Supervision & Interpretation of Selective Angiography
CPT code 75774 designates the radiological supervision and interpretation for selective angiography studies of additional blood vessels performed after the primary angiographic examination. Angiography uses radiopaque contrast to visualize vascular anatomy and is essential for diagnosing vascular disease and guiding interventional treatment. Nationally, accurate coding of supervision and interpretation services affects clinical documentation, billing clarity, and appropriate payment for added imaging work.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for using CPT code 75774, typical sites of service, and common billing modifiers associated with radiology supervision and interpretation. The publication also outlines benchmarking and coverage considerations, coding nuances for separate procedures performed after the basic examination, and how this code is positioned relative to primary angiographic service lines.
This summary gives clinicians, coders, and revenue-cycle professionals a focused reference on when CPT code 75774 is reported, why it is reported as a separate supervisory/interpretive service, and what sections of payer policy and claims processing are most relevant nationally. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 75774 describes radiological supervision and interpretation of selective angiography studies of additional blood vessels performed after the basic angiographic examination. Angiography is an X‑ray study that uses a radiopaque contrast agent to visualize blood vessels to help diagnose and guide treatment of vascular conditions.
-
Service type: Diagnostic radiological supervision and interpretation for selective angiographic studies performed in addition to the primary angiographic exam.
-
Typical site of service: Hospital radiology departments, outpatient imaging centers, and interventional suites where angiographic procedures are performed.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with progressive claudication and suspected peripheral arterial disease is referred for vascular imaging. After a diagnostic lower extremity arterial angiogram identifies disease in the superficial femoral artery, the interventional radiologist performs selective catheterization of a tibial branch for additional targeted imaging. Radiological supervision and interpretation for this selective study is documented separately from the primary angiographic series. The procedure typically occurs in an outpatient endovascular suite, hospital radiology department, or catheterization laboratory with fluoroscopic capability. The workflow includes pre-procedure consent, intravenous access, arterial access (commonly femoral), selective catheter placement, administration of radiopaque contrast, image acquisition of the additional targeted vessel territory, interpretation by the attending physician, and documentation of the selective study as an add-on service to the primary angiography using the appropriate CPT code and modifiers.
