About 78740: Radionuclide ureteral reflux study
Reports radionuclide imaging of the bladder and upper urinary tract to evaluate suspected urine reflux from the bladder into the ureters.
This nuclear medicine study evaluates whether urine flows backward from the bladder into the ureters, and sometimes toward the kidneys. A radiopharmaceutical is introduced into the bladder and images are obtained during filling and voiding. It is commonly used when vesicoureteral reflux is suspected, including in the evaluation of recurrent urinary tract infections, and may be performed in a nuclear medicine or radiology department. A nuclear medicine physician or radiologist interprets the images.
Select this code when the documented examination is a radionuclide ureteral reflux study, rather than imaging focused on renal drainage or bladder emptying. The record should support the reflux question and the imaging performed. Modifier 26 identifies the interpretation, while modifier TC identifies the equipment-and-staff service; an unmodified claim represents the global service, including both components. CMS separately prices the 26 and TC components.

78740 billing questions
How does this differ from a fluoroscopic voiding cystourethrogram?
This code is for radionuclide imaging of reflux. CPT 74455 describes the fluoroscopic voiding cystourethrography approach.
When should modifier 26 or TC be used?
Use modifier 26 for the physician's interpretation and modifier TC for the technical service. Submit without either modifier when billing the global service.
What documentation supports this study?
Document the clinical concern for ureteral reflux and the radionuclide imaging performed to evaluate it. The report should support the physician's interpretation when billing modifier 26.
Is this the right code for a renal drainage study?
No. A study focused on renal flow or drainage, such as CPT 78708, is distinct from imaging for reflux from the bladder into the ureters.
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.
