What 74430 covers
This study images the bladder after contrast is introduced retrograde through a urethral catheter. Fluoroscopic images, sometimes with a preliminary or follow-up abdominal image, can help assess bladder integrity, including a suspected leak after pelvic trauma or bladder surgery. A radiologist typically interprets the study in a hospital radiology department or outpatient imaging setting; the contrast instillation may be performed by another clinician.
Report 74430 for the retrograde bladder imaging service, not for a study that images the bladder during voiding. Documentation should identify the bladder contrast examination, the images obtained, and the interpreting clinician’s findings. The service may be billed globally, or divided between the professional interpretation (modifier 26) and the technical service, including equipment and staff (modifier TC). CMS separately prices both components.

74430 billing questions
How does this differ from a voiding cystourethrogram?
Use 74430 for retrograde bladder imaging that is not performed during voiding. A study that images the urethra and bladder during voiding is reported with 74455.
Can the contrast instillation be reported separately?
Code 51600 describes the injection procedure for cystography and may be reported with 74430 when that service is performed and documented.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and report, or modifier TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports 74430?
The record should show a retrograde contrast examination of the bladder, the imaging performed, and the interpretation. A study performed during voiding points to 74455 instead.
Is 74430 reported for each image?
No. It represents the bladder imaging study, rather than an individual image.
