Official Description

Closure of vesicovaginal fistula, abdominal approach

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A vesicovaginal fistula is a pathological condition characterized by an abnormal connection between the bladder and the vagina, resulting in the involuntary passage of urine into the vaginal canal. This condition can lead to significant physical and emotional distress for affected individuals. The surgical procedure denoted by CPT® Code 51900 involves an abdominal approach to effectively close this fistula. During the operation, the abdomen is surgically opened to gain access to the bladder. The surgeon carefully exposes the bladder and makes an incision to locate the fistula tract. This process includes catheterizing the ureters to ensure proper identification and management of the urinary system. The fistula tract is excised, along with any associated scar or necrotic tissue, to promote healing and restore normal anatomy. The procedure also involves meticulous dissection of the bladder wall from surrounding structures, followed by the closure of both the vaginal wall and bladder wall defects. This comprehensive approach aims to eliminate the abnormal passage and restore normal urinary function, thereby improving the quality of life for the patient.

1. Indications

The closure of a vesicovaginal fistula via an abdominal approach is indicated in the following scenarios:

  • Vesicovaginal Fistula The primary indication for this procedure is the presence of a vesicovaginal fistula, which may result from various causes such as childbirth trauma, pelvic surgery, or radiation therapy.
  • Urinary Incontinence Patients experiencing urinary incontinence due to the abnormal connection between the bladder and vagina may require this surgical intervention to restore normal urinary function.
  • Quality of Life Impairment Individuals suffering from the physical and psychological impacts of a vesicovaginal fistula, including social embarrassment and hygiene issues, may be candidates for this procedure to improve their overall quality of life.

2. Procedure

The procedure for the closure of a vesicovaginal fistula through an abdominal approach involves several critical steps:

  • Step 1: Abdominal Incision The surgical process begins with an incision in the abdominal wall to access the bladder. This step is crucial for providing the surgeon with the necessary visibility and access to the affected area.
  • Step 2: Bladder Exposure Once the abdomen is opened, the bladder is carefully exposed. This involves retracting surrounding tissues to ensure that the bladder is fully accessible for the subsequent steps of the procedure.
  • Step 3: Incision in the Bladder An incision is made in the bladder to locate the fistula tract. This step is essential for identifying the abnormal connection that needs to be repaired.
  • Step 4: Catheterization of Ureters The ureters are catheterized to facilitate proper drainage and to prevent any injury to the urinary system during the procedure. This ensures that the urinary flow is managed effectively throughout the surgery.
  • Step 5: Identification of Fistula Tract The fistula tract is located through careful dissection and examination of the bladder. This step is critical for ensuring that the entire fistula and any associated tissue are adequately addressed.
  • Step 6: Placement of Stay Sutures Stay sutures are placed around the fistula tract to stabilize the area and facilitate its excision. This technique helps in managing the tissue during the repair process.
  • Step 7: Excision of Fistula Tract The fistula tract, along with any scar tissue or necrotic tissue, is excised. This step is vital for removing the abnormal tissue and promoting healing.
  • Step 8: Dissection of Bladder Wall The bladder wall is dissected free from the endopelvic fascia and vaginal wall to ensure that the repair can be performed without tension on the surrounding structures.
  • Step 9: Closure of Vaginal Wall Defect The defect in the vaginal wall is closed using appropriate suturing techniques to restore the integrity of the vaginal structure.
  • Step 10: Closure of Bladder Wall Defect Following the closure of the vaginal wall, the bladder wall defect is also closed, ensuring that the bladder is properly sealed and functional.
  • Step 11: Removal of Ureteral Catheters After confirming that the repairs are secure, the ureteral catheters are removed, allowing for normal urinary function to resume.
  • Step 12: Closure of Cystotomy Finally, the cystotomy, or bladder incision, is closed, completing the surgical procedure.

3. Post-Procedure

Post-procedure care following the closure of a vesicovaginal fistula includes monitoring for any signs of complications such as infection or urinary retention. Patients may require a catheter for a period to ensure proper urinary drainage while the bladder heals. Follow-up appointments are essential to assess the success of the repair and to monitor the patient's recovery. Patients are typically advised on activity restrictions and may need to avoid strenuous activities for a specified duration to promote healing. Additionally, education on signs of complications and the importance of adhering to follow-up care is crucial for optimal recovery.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
