CPT code 71275 denotes a computed tomographic angiography (CTA) of the chest performed with contrast to visualize thoracic blood vessels excluding the heart. This imaging code is widely used for evaluation of pulmonary arteries, aortic pathology, and other vascular conditions in the chest where high-resolution arterial-phase imaging is required. Nationally, CTA chest studies represent a significant share of advanced diagnostic imaging utilization and are central to acute care pathways for suspected pulmonary embolism and vascular injury.
