Official Description

Closure of rectovaginal fistula; vaginal or transanal approach

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 57300 involves the surgical closure of a rectovaginal fistula, which is an abnormal connection between the rectum and the vagina. This condition can be either congenital, meaning present at birth, or acquired due to various factors. Acquired rectovaginal fistulas may arise from infections, traumatic injuries to the perineum during childbirth, complications following surgical procedures involving the vagina or rectum, or as a result of radiation therapy for cancer treatment. The closure can be performed using either a vaginal or transanal approach, depending on the specific circumstances and anatomy of the patient. In the vaginal approach, the surgeon elevates the vaginal mucosa surrounding the fistula to expose it, followed by the placement of purse-string sutures to invert the fistula into the rectal lumen, ultimately closing the vaginal mucosa. Conversely, the transanal approach utilizes an anoscope to locate the fistula, where an advancement flap of mucosal and submucosal tissue is created, and in some cases, muscle tissue is also involved. The procedure includes debriding the fistula tract, suturing the muscle tissue over the fistula, excising the tip of the fistula in the rectum, and advancing the flap to cover the closed fistula tract, while leaving the vaginal side of the fistula open. This detailed surgical intervention aims to restore normal anatomy and function, alleviating the complications associated with rectovaginal fistulas.

1. Indications

The closure of a rectovaginal fistula is indicated in the following situations:

  • Congenital Fistula A rectovaginal fistula that is present at birth, requiring surgical intervention to correct the abnormal passage.
  • Infection Fistulas that develop as a result of infections that compromise the integrity of the rectal or vaginal tissues.
  • Trauma from Childbirth Fistulas that occur due to injuries sustained during vaginal delivery, which may lead to abnormal connections between the rectum and vagina.
  • Surgical Complications Fistulas that arise as complications from previous surgical procedures involving the rectum or vagina.
  • Radiation Therapy Complications Fistulas that develop as a result of radiation treatment for malignancies affecting the pelvic region.

2. Procedure

The procedure for closing a rectovaginal fistula can be performed using either a vaginal or transanal approach, depending on the specific case and the surgeon's assessment.

  • Vaginal Approach In this method, the surgeon elevates the vaginal mucosa surrounding the fistula to expose it adequately. Purse-string sutures are then placed around the fistula, allowing it to be inverted into the rectal lumen. Following this, the vaginal mucosa is closed to complete the procedure.
  • Transanal Approach This approach begins with the use of an anoscope to identify the fistula. The surgeon outlines an advancement flap of mucosal and submucosal tissue, which is then elevated. In some cases, muscle tissue may also be required for the repair. The fistula tract is debrided to remove any unhealthy tissue, and the muscle tissue is sutured closed over the fistula. The tip of the fistula located in the rectum, above the closed muscle tissue, is excised. Finally, the flap is advanced and sutured over the closed fistula tract, while the vaginal side of the fistula is intentionally left open.

3. Post-Procedure

Post-procedure care for patients who have undergone closure of a rectovaginal fistula typically involves monitoring for any signs of complications, such as infection or recurrence of the fistula. Patients may be advised on specific hygiene practices to maintain the surgical site and prevent infection. Follow-up appointments are essential to assess healing and ensure that the fistula has been successfully closed. Additionally, patients may receive guidance on dietary modifications and activity restrictions during the recovery period to promote optimal healing.

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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, 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).
