Summary & Overview
CPT 57311: Urethrovaginal Fistula Repair with Bulbocavernosus Muscle Flap
CPT code 57311 designates a surgical procedure to repair a urethrovaginal fistula using the bulbocavernosus muscle to create protective flaps over the repair. This reconstructive operation addresses abnormal communications between the urethra and vagina that can cause urinary leakage, recurrent infections, and functional impairment. The procedure is clinically significant given its role in restoring continence and pelvic floor integrity and is performed by gynecologic and urologic surgeons with reconstructive training.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical care settings, benchmark considerations relevant to hospital and ambulatory surgery environments, and policy-relevant notes on coverage and coding practice. The publication outlines common billing modifiers and service-line implications and highlights areas where documentation and coding specificity affect payment and quality measurement.
This summary is intended for national audiences including coding professionals, clinicians involved in pelvic reconstructive surgery, and payer policy staff seeking clarity on clinical indications, procedural context, and where coding specificity may influence administrative and reimbursement workflows. Data not available in the input is identified as such in the detailed sections.
Billing Code Overview
CPT code 57311 describes a surgical repair of a urethrovaginal fistula using the bulbocavernosus muscle to create flaps that cover the repair site. The procedure is a form of fistula repair in which the surgeon mobilizes local perineal musculature to reinforce and protect the closure of a urethral defect communicating with the vagina.
-
Service type: Surgical repair of urethrovaginal fistula using local muscle flap reconstruction
-
Typical site of service: Operating room or ambulatory surgery center, commonly performed by gynecologic surgeons or urologic surgeons with reconstructive expertise
Clinical & Coding Specifications
Clinical Context
A 38-year-old female presents with persistent urinary leakage and recurrent urinary tract infections following obstructed labor and vaginal delivery 2 years earlier. Physical examination reveals a vesicovaginal/urethrovaginal fistula with symptoms of continuous urinary dribbling and perineal discomfort. Prior conservative management including catheter drainage and local wound care failed. The urogynecology team schedules an operative repair under general anesthesia. The procedure involves a transvaginal approach with excision of fistulous tract, layered repair of the urethral and vaginal walls, and mobilization of bilateral bulbocavernosus muscle flaps to cover and reinforce the urethrovaginal repair (procedure coded as 57311). Intraoperative cystoscopy confirms fistula location and ureteral patency. A urethral catheter is left in place postoperatively for bladder drainage while the repair heals. Typical workflow includes preoperative evaluation (history, pelvic exam, urinalysis), anesthesia clearance, intraoperative cystoscopy, fistula repair with muscle flap, postoperative inpatient observation for 24–48 hours, catheter management, and follow-up visits for wound and continence assessment.
