Official Description

Incision and drainage of deep supralevator, pelvirectal, or retrorectal abscess

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 45020 refers to the procedure of incision and drainage of a deep supralevator, pelvirectal, or retrorectal abscess. This surgical intervention is necessary when there is a collection of pus located in the deeper regions of the pelvic area, specifically above the levator ani muscle, around the rectum, or behind the rectum. The procedure aims to relieve pressure, remove infected material, and promote healing. During the process, a proctoscope or sigmoidoscope may be utilized to accurately locate the abscess. The technique involves making incisions, typically radial or cruciate, to ensure adequate drainage of the abscess. The specific approach taken depends on the abscess's location and origin, with careful dissection and probing to ensure complete drainage and to check for any associated complications, such as fistulous tracts. This procedure is critical for managing infections that can lead to significant morbidity if left untreated.

1. Indications

The procedure described by CPT® Code 45020 is indicated for the following conditions:

  • Deep Supralevator Abscess - An abscess located above the levator ani muscle, often requiring surgical intervention for drainage.
  • Pelvirectal Abscess - An abscess situated in the pelvic region near the rectum, necessitating incision and drainage to alleviate infection and pressure.
  • Retrorectal Abscess - An abscess found behind the rectum, which may require a more complex approach for effective drainage.

2. Procedure

The procedure for incision and drainage of a deep supralevator, pelvirectal, or retrorectal abscess involves several critical steps:

  • Step 1: Identification of the Abscess - The surgeon begins by using a proctoscope or sigmoidoscope to locate the abscess accurately. This visualization is essential for determining the appropriate approach for drainage.
  • Step 2: Incision Making - Depending on the abscess's location, the surgeon makes a radial or cruciate incision over the area of fluctuance, which is the point where the abscess is most prominent. This incision is made as close to the anal verge as possible to facilitate effective drainage.
  • Step 3: Exposure of the Abscess Cavity - The edges of the incision are excised to expose the abscess cavity fully. This step is crucial for allowing wide drainage of the infected material.
  • Step 4: Drainage of the Abscess - The abscess cavity is probed using a gloved finger to break up any loculations, ensuring that all infected material is evacuated. The cavity is inspected for any fistulous tracts that may need to be addressed.
  • Step 5: Post-Drainage Management - After the abscess has been drained, the incisions may be left open to allow for continued drainage, packed with iodophor gauze for 24 hours, or a drain may be placed to facilitate ongoing drainage and prevent re-accumulation of pus.

3. Post-Procedure

Post-procedure care for patients undergoing incision and drainage of a deep supralevator, pelvirectal, or retrorectal abscess includes monitoring for signs of infection, ensuring proper wound care, and managing any pain or discomfort. Patients may be advised on how to care for the incision site, including keeping it clean and dry. Follow-up appointments are typically scheduled to assess healing and to check for any complications, such as the formation of new abscesses or fistulas. The recovery period may vary depending on the extent of the procedure and the patient's overall health.

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.
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.)
