Radiology
About 74455: Voiding urethrocystography interpretation
Reports radiologic supervision and interpretation of a contrast study that images the bladder and urethra during voiding, commonly to assess reflux or obstruction.
This study, commonly called a voiding cystourethrogram, uses fluoroscopic imaging as contrast fills the bladder and the patient voids. The images show the bladder and urethra during emptying and can demonstrate vesicoureteral reflux or urethral obstruction. It is commonly performed in radiology departments for children being evaluated for urinary tract abnormalities, including after recurrent febrile urinary infections, and may also be used for suspected urethral problems in adults. A radiologist interprets the images and reports the findings.
Report 74455 for the radiologic service when the study captures the voiding phase and evaluates the urethra and bladder; a bladder-only cystogram or a retrograde urethral study represents a different imaging service. Documentation should identify the clinical indication and describe the imaging and interpretation, including relevant findings during voiding. The contrast instillation service, when performed, is commonly reported separately with 51600. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and reporting without either modifier represents the global service.

74455 billing questions
When should 74455 be used instead of 74430?
Use 74455 when imaging includes the voiding phase to evaluate the urethra and bladder. Code 74430 is for a bladder cystography study rather than a voiding urethrocystography.
How does 74455 differ from 74450?
74455 covers imaging during voiding. 74450 is used for retrograde urethrocystography, in which contrast is introduced retrograde rather than evaluating the urinary tract during voiding.
Can 51600 be reported with 74455?
Yes. When contrast is instilled for the study, 51600 may be reported for the injection procedure, while 74455 represents the radiologic service and interpretation.
Which modifier identifies the radiologist's interpretation?
Append modifier 26 for the professional component. Modifier TC identifies the technical component, and the unmodified code represents the global service.
What documentation supports 74455?
The record should support a voiding study of the bladder and urethra, the clinical indication, and the radiologist's interpretation of the images, including findings observed during voiding.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
