CPT code 72191 represents pelvic computed tomographic angiography (CTA), a contrast-enhanced CT study that visualizes the arterial and venous vasculature of the pelvis with computerized image selection and reconstruction. Nationally, this imaging code matters for vascular diagnosis, preoperative planning, and emergency evaluation of pelvic bleeding or ischemia. Utilization patterns for pelvic CTA influence imaging capacity, contrast media use, and radiology workflow.

Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coverage considerations, typical sites of service, and operational implications for radiology departments and outpatient imaging centers. The publication summarizes reimbursement benchmarks where available, common billing modifiers used with advanced imaging services, and relevant clinical contexts in which pelvic CTA is commonly ordered (for example, assessment of pelvic trauma, vascular occlusive disease, and preprocedural mapping).

This national-level brief provides clinicians, billing professionals, and policy analysts with concise context on CPT code 72191, highlighting service definition, typical delivery settings, and the types of benchmarks and policy updates that affect coding and payment for pelvic CTA.
