Official Description

Drainage of retroperitoneal abscess, open

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A retroperitoneal abscess is defined as a localized collection of pus situated in the abdominal cavity, specifically behind the peritoneum, which is the membrane lining the abdominal wall and covering the abdominal organs. This type of abscess may also be referred to as an extraperitoneal abscess due to its location outside the peritoneal cavity. The procedure coded as CPT® 49060 involves the surgical drainage of this abscess through an open approach. Surgeons can access the retroperitoneum via various incisions, including an anterior or posterior subcostal incision, a midline abdominal incision, or a flank incision, depending on the specific circumstances and location of the abscess. During the procedure, the entire retroperitoneal cavity is thoroughly explored to locate the abscess. Once identified, loculations within the abscess are separated, and all debris, which may consist of pus, blood, and necrotic tissue, is meticulously evacuated. To ensure complete removal of all infectious material, the abscess site is vigorously irrigated with sterile saline or an antibiotic solution. Following the irrigation, a drain is strategically placed within the abscess cavity to facilitate ongoing drainage, and the incision is then closed around the drain to promote healing while allowing for continued monitoring and management of the abscess site.

1. Indications

The procedure coded as CPT® 49060 is indicated for the management of a retroperitoneal abscess, which may arise due to various underlying conditions. The following are specific indications for performing this procedure:

  • Presence of a Retroperitoneal Abscess - The primary indication for this procedure is the confirmed diagnosis of a retroperitoneal abscess, which may present with symptoms such as abdominal pain, fever, and signs of infection.
  • Failure of Conservative Management - When initial conservative treatments, such as antibiotics or percutaneous drainage, are ineffective in resolving the abscess, surgical intervention becomes necessary.
  • Complications from the Abscess - The presence of complications, such as sepsis or significant pain, may warrant immediate surgical drainage to prevent further deterioration of the patient's condition.

2. Procedure

The procedure for the drainage of a retroperitoneal abscess involves several critical steps, each designed to ensure effective management of the abscess while minimizing complications:

  • Step 1: Incision - The procedure begins with the selection of an appropriate incision site, which may be an anterior or posterior subcostal incision, a midline abdominal incision, or a flank incision. The choice of incision depends on the location of the abscess and the surgeon's preference. The incision is made to provide adequate access to the retroperitoneal space.
  • Step 2: Exploration of the Retroperitoneal Cavity - Once the incision is made, the surgeon carefully explores the entire retroperitoneal cavity. This exploration is crucial for identifying the abscess and assessing its extent, as well as any associated structures that may be affected.
  • Step 3: Loculation Separation and Debris Evacuation - After locating the abscess, the surgeon separates any loculations within the abscess. This step is essential to ensure that all pockets of pus are accessed. The surgeon then proceeds to evacuate all debris, which may include pus, blood, and necrotic tissue, to promote healing and reduce the risk of infection.
  • Step 4: Irrigation - Following the evacuation of debris, the abscess site is vigorously irrigated with sterile saline or an antibiotic solution. This irrigation is performed to ensure that all infectious material is removed and to help cleanse the area, reducing the likelihood of postoperative complications.
  • Step 5: Drain Placement - After thorough irrigation, a drain is placed within the abscess cavity. The drain serves to facilitate ongoing drainage of any residual fluid or pus, thereby preventing the reaccumulation of the abscess.
  • Step 6: Closure of the Incision - Finally, the incision is closed around the drain. This closure is performed in a manner that allows for continued drainage while promoting healing of the surgical site.

3. Post-Procedure

Post-procedure care following the drainage of a retroperitoneal abscess is critical for ensuring proper recovery and monitoring for potential complications. Patients are typically observed for signs of infection, such as fever or increased pain at the incision site. The drain placed during the procedure will require regular monitoring to assess the output and ensure it is functioning correctly. Patients may also be prescribed antibiotics to prevent infection. Follow-up appointments are essential to evaluate the healing process and to determine if further intervention is necessary. Additionally, patients should be educated on signs of complications, such as persistent abdominal pain or changes in drainage, which should prompt immediate medical attention.

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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient 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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
