Summary & Overview
CPT 74455: Voiding Urethrocystography Imaging Supervision and Interpretation
CPT code 74455 represents imaging supervision and interpretation for a voiding urethrocystography, a fluoroscopic study used to assess bladder and urethral anatomy and voiding function. This code is used when the provider bills only for the professional and technical interpretation components of the voiding cystourethrogram. Nationally, the code is important for radiology departments and urology practices that evaluate patients with urinary dysfunction, recurrent urinary tract infections, suspected vesicoureteral reflux, or obstructive symptoms.
Key payers commonly relevant for reimbursement and coverage policies include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise benchmarks and context for coding and billing workflow, an overview of clinical indications and typical settings where the service is delivered, and a summary of common administrative modifiers used with imaging supervision and interpretation services. The publication also highlights billing considerations surrounding professional and technical component reporting and clarifies the scope of CPT code 74455 compared with other radiologic urologic studies.
This national summary is intended to orient revenue cycle staff, radiology and urology clinicians, and policy analysts to the clinical purpose of the code, who commonly pays for the service, and which operational topics to review when coding and documenting voiding urethrocystography exams.
Billing Code Overview
CPT code 74455 describes imaging supervision and interpretation for a voiding urethrocystography. This procedure involves fluoroscopic imaging of the bladder and urethra during filling and voiding to evaluate voiding function and identify structural or functional abnormalities.
-
Service type: Imaging supervision and interpretation (radiologic diagnostic procedure)
-
Typical site of service: Outpatient radiology or hospital imaging suite where fluoroscopic voiding studies are performed.

Clinical & Coding Specifications
Clinical Context
A 7-year-old boy with a history of recurrent urinary tract infections and daytime urinary incontinence is referred to pediatric urology. The child reports dysuria and a history of febrile UTIs despite prophylactic antibiotics. After urinary culture and renal ultrasound, the urologist orders a voiding urethrocystography to evaluate for vesicoureteral reflux and urethral/bladder outlet abnormalities. The patient arrives at the radiology suite; the technologist explains the procedure, obtains informed consent from the parent, and places a sterile urinary catheter. Under fluoroscopic guidance, contrast is instilled into the bladder while the patient is observed during filling and voiding phases. The interpreting provider performs imaging supervision and interpretation, documents findings (presence and grade of reflux, urethral anatomy, bladder contour), and finalizes a report. The study represented by 74455 includes both technical and professional components for imaging supervision and interpretation, billed when the provider is reporting the imaging interpretation component for the voiding cystourethrogram.
