CPT code 50385 covers transurethral removal and replacement of an internally dwelling ureteral stent performed with imaging guidance and without endoscopic instrumentation. This procedure is commonly performed to manage ureteral obstruction, stent malfunction, or to exchange indwelling stents, and it matters nationally because it affects surgical workflow, site-of-service decisions, and payment policies across outpatient settings. Payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical and procedural scope of the code, typical sites of service, and common modifiers associated with billing for this service. The publication provides benchmarking context and policy-relevant considerations related to coding and site-of-service classification, along with clinical context that clarifies when a transurethral, image-guided approach without endoscopy is reported. Where input data is absent, the summary notes those gaps: associated taxonomies, specific ICD-10 diagnoses, and related codes are not available in the input. This national overview is intended to help coding professionals, payers, and health system administrators understand the fundamental use and reporting considerations for CPT code 50385.
