CPT code 74410 designates an intravenous pyelogram (IVP) — an X-ray examination of the kidneys, ureters, and bladder performed after intravenous administration of contrast. This diagnostic radiology code matters nationally because it is used to image urinary tract anatomy and detect obstruction, stones, or structural abnormalities; appropriate coding affects claims processing, clinical documentation, and utilization monitoring across hospitals and outpatient imaging centers. Key payers typically engaged in national reimbursement and coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context for using 74410, the typical sites where the service is delivered, and which payers are relevant for national policy and coverage patterns. The publication includes benchmarks and payer-focused considerations, summaries of common modifiers and billing practice notes, and a concise clinical overview linking the procedure to common indications. Data not available in the input is clearly noted where applicable.
