CPT code 50705 is an add-on image-guided urologic procedure used to deliberately occlude the ureter, typically employed when urinary diversion via nephrostomy has failed to resolve a ureterovaginal fistula. The code specifies use of ultrasound and/or fluoroscopy with radiological supervision and interpretation, reflecting a specialized interventional service that intersects urology and interventional radiology. Nationally, this code matters because it identifies a targeted, resource-intensive intervention for complex urinary tract complications and carries implications for facility resources, imaging utilization, and care coordination. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a concise clinical and billing overview of CPT code 50705, including the service context, typical site of service, and common modifiers and payer considerations where available. The publication also outlines benchmarking and policy-relevant points for payers and administrators, and provides clinical context on when an add-on ureteral occlusion is used.
