Summary & Overview
CPT 75605: Thoracic Aortography Imaging Supervision and Interpretation
CPT code 75605 denotes the physician or qualified provider component for imaging supervision and interpretation of thoracic aortography with serialography. Nationally, it covers the diagnostic imaging oversight and formal interpretation elements essential to vascular imaging workflows for thoracic aortic evaluation. This code matters because clear reporting of supervision and interpretation separates professional services from technical imaging components and affects documentation, billing clarity, and appropriate reimbursement for specialist clinicians.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for thoracic aortography with serial imaging, an outline of expected sites of service, and which stakeholders typically process claims for the professional component. The publication also summarizes common modifiers used with professional imaging codes and highlights areas where policy or billing practice may affect claim adjudication.
This resource provides operational guidance on claim reporting (professional-only reporting), coding boundaries with technical components, and typical clinical scenarios where 75605 is applicable. Data not available in the input is noted where specific benchmarks, payer-specific rules, or associated taxonomies and ICD-10 diagnoses would normally appear.

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with known thoracic aortic aneurysm presents with worsening chest pain and a new interarm blood pressure differential. Noninvasive imaging (CT angiography) provided limited evaluation of proximal arch anatomy due to motion artifact. The vascular surgery team requests invasive thoracic aortography with serialography to define luminal morphology and branch takeoff prior to endovascular repair. In the angiography suite the patient is prepped and moderate sedation is administered. An interventional radiologist or vascular surgeon supervises imaging acquisition while a technologist performs the angiographic runs; the interpreting physician reviews the serialography images and dictatesthe formal report. The service reported by code 75605 represents only the imaging supervision and interpretation component of thoracic aortography with serialography; technical services (catheterization, contrast, facility resources) are billed separately. Typical site of service is an outpatient or hospital-based angiography/interventional suite or catheterization laboratory.
