Radiology
About 74485: Fluoroscopic urinary passage dilation imaging
Radiological supervision and interpretation for fluoroscopic dilation of a narrowed ureter or urethra, reported with the associated dilation procedure.
CPT 74485 represents the radiology work for imaging-guided dilation of a narrowed urinary passage, such as a ureteral or urethral stricture. Fluoroscopy helps the treating urologist or interventional radiologist visualize the target and assess the dilation. The service is performed in settings such as an operating room or interventional suite when imaging is used as part of the dilation procedure; it is not simply a diagnostic contrast examination of the urinary tract.
Report 74485 when the documented service includes radiological supervision and interpretation for the dilation, rather than only the therapeutic procedure or a separate diagnostic study. The record should identify the treated passage, describe the imaging performed, and include the interpreting physician’s findings. CMS recognizes separately priced professional and technical components: append modifier 26 for the interpretation, modifier TC for the equipment and staff portion, or report the code without a component modifier for the global service. The applicable component should match the service furnished and billed.
CMS billing rules for 74485
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

74485 billing questions
How is 74485 different from a urethrogram or urography code?
74485 covers radiological supervision and interpretation associated with dilation of a narrowed urinary passage. Codes such as 74420 or 74450 describe contrast examinations, not the dilation-imaging service.
When should modifier 26 or TC be used?
Use modifier 26 for the physician’s interpretation and modifier TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports 74485?
Document the ureteral or urethral target, the dilation performed under imaging, and the interpreting physician’s findings. The report should support the radiological supervision and interpretation, not just the therapeutic dilation.
Can 74485 be reported with the dilation procedure?
It may be reported with the therapeutic procedure when the radiological service is separately documented and furnished. The dilation procedure code describes the treatment; 74485 represents the related imaging supervision and interpretation.
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.
