Summary & Overview
CPT 51820: Bladder and Urethral Repair with Ureteral Reimplantation
CPT code 51820 denotes a surgical repair of bladder and urethral defects combined with reimplantation of one or both ureters into the bladder. This code covers complex reconstructive urologic surgery intended to correct anatomical abnormalities that impede urinary function. Nationally, procedures captured by this code are clinically significant because they address conditions that can lead to recurrent infections, renal damage, or impaired quality of life if left untreated.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common billing considerations tied to this reconstructive urology procedure. The publication outlines benchmarks and utilization patterns where available, highlights relevant policy updates affecting coverage and coding, and summarizes clinical circumstances under which the procedure is commonly performed. Data limitations are noted where input was not provided. The content is intended for national audiences including coding professionals, practice administrators, and policy analysts seeking a clear, practical summary of CPT code 51820 and its role in surgical urologic care.
Billing Code Overview
CPT code 51820 describes a surgical procedure to correct defects of the urinary bladder and urethra with concurrent reimplantation of one or both ureters into the bladder. The procedure typically addresses congenital or acquired anatomic abnormalities that impair urinary storage or drainage and may be performed to restore normal urinary tract continuity and function.

Clinical & Coding Specifications
Clinical Context
A typical patient is a pediatric or adult patient presenting with urinary incontinence, recurrent urinary tract infections, hydronephrosis, or vesicoureteral reflux (VUR) refractory to conservative management. Common presenting history includes febrile UTIs in childhood, prenatal hydronephrosis detected on ultrasound, or acquired bladder neck/urethral defects after trauma or prior surgery. Diagnostic workup includes renal and bladder ultrasound, voiding cystourethrogram (VCUG), renal scintigraphy when indicated, urinalysis, urine culture, and urodynamic testing if dysfunction is suspected. The typical workflow for 51820 begins with preoperative evaluation and imaging confirming bladder and urethral defects with ureteral reflux or malposition. Under general anesthesia, the surgical team performs bladder repair and urethral reconstruction with reimplantation of one or both ureters into the bladder to restore competence and prevent reflux. Intraoperative steps include cystoscopic assessment, mobilization of ureter(s), creation of a submucosal tunnel or reimplantation site, layered bladder and urethral closure, and placement of stents or drains as indicated. Postoperative care involves catheter management, pain control, monitoring for hematuria or infection, antibiotic prophylaxis as appropriate, and follow-up imaging (ultrasound or VCUG) to confirm anatomic and functional repair. Typical sites of service are inpatient hospital operating rooms or ambulatory surgical centers depending on patient age, comorbidity, and expected complexity. The service type is operative/surgical reconstructive urologic procedure.
