Summary & Overview
CPT 75600: Thoracic Aortography Imaging Supervision and Interpretation
CPT code 75600 designates the professional component for thoracic aortography imaging — specifically supervision and interpretation of a thoracic aortogram performed without serialography. It matters nationally because it separates the provider’s interpretive and supervisory work from technical imaging services, affecting billing, claims adjudication, and Medicare and commercial payment policies for vascular imaging procedures. Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise explanation of what CPT code 75600 represents, how it is used in imaging service lines, and the typical clinical context for thoracic aortography. The publication summarizes payer coverage patterns and common billing modifiers, highlights implications for facility versus professional billing, and outlines benchmarking and policy considerations affecting reimbursement and claims processing.

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of hypertension and peripheral vascular disease presents with sudden onset chest and back pain. The vascular surgery team requests imaging to evaluate for suspected thoracic aortic aneurysm or acute aortic pathology. The patient is transported to the angiography suite where an interventional radiologist or vascular surgeon supervises acquisition of thoracic aortography images without serialography while a technologist or radiology nurse manages contrast administration and image capture. The supervising physician reviews real-time fluoroscopic images, provides interpretation, documents findings (including aortic contour, presence of aneurysm, dissection flap, or extravasation), and communicates results to the referring clinician. Billing captures only the imaging supervision and interpretation component for thoracic aortography using 75600 when the facility reports the technical component separately or the technical services are provided by others.
