As a commonly billed vascular imaging service, it affects outpatient imaging utilization, vascular lab workflows, and payer coverage policies.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find information on national benchmarking for utilization and reimbursement patterns, typical sites of service, clinical context for ordering the study, and common billing considerations.
