Summary & Overview
CPT 78730: Ureteral Reflux Study with Bladder Function Radioisotope Evaluation
CPT code 78730 denotes a combined diagnostic procedure that evaluates vesicoureteral reflux and bladder functional defects using a radioisotope during a ureteral reflux study. This mixed imaging and functional assessment matter nationally because it informs management of pediatric and adult patients with recurrent urinary tract infections, suspected reflux, or bladder dysfunction, and influences utilization of nuclear medicine services in outpatient and hospital settings. Key payers typically involved in coverage and payment decisions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical intent of the code, the typical care setting, and the scope of services captured by the code. The publication also summarizes common billing modifiers associated with this type of service, outlines where this procedure fits in clinical workflows, and highlights points payers commonly consider when adjudicating claims.

Billing Code Overview
CPT code 78730 describes a diagnostic procedure in which a provider performs a ureteral reflux study while simultaneously using a radioisotope to evaluate functional defects in the urinary bladder. The procedure assesses both vesicoureteral reflux and bladder function by combining fluoroscopic or radionuclide reflux imaging with radionuclide assessment of bladder dynamics.
-
Service type: Nuclear medicine diagnostic study combined with urinary tract/voiding function assessment
-
Typical site of service: Hospital outpatient department or ambulatory imaging center
Clinical & Coding Specifications
Clinical Context
A pediatric patient with a history of recurrent febrile urinary tract infections is referred for evaluation of suspected vesicoureteral reflux and bladder dysfunction. The clinician performs a radionuclide cystogram with simultaneous ureteral reflux study using a radioisotope to detect reflux and to evaluate functional defects of the urinary bladder (such as post-void residual, bladder emptying dysfunction, or intravesical reflux). The procedure is typically scheduled in an outpatient radiology or nuclear medicine department, or in a hospital outpatient imaging suite. The workflow includes: pre-procedure consent and allergy screening, catheterization of the bladder, instillation of a tracer-labeled saline or radiopharmaceutical, acquisition of dynamic gamma camera imaging during filling and voiding phases, post-void imaging to assess residual activity, interpretation by a radiologist or nuclear medicine physician, and documentation of findings including presence/grade of reflux and any functional bladder abnormality. The patient may require supervision by pediatric nursing staff and may be discharged the same day with follow-up arranged with the referring pediatrician or pediatric urologist.
