Official Description

Suture, secondary, of abdominal wall for evisceration or dehiscence

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 49900 refers to the procedure of secondary suture of the abdominal wall specifically for cases of evisceration or dehiscence. Dehiscence is a medical term that describes the reopening of a surgical wound or incision that was previously closed with sutures. This condition can occur due to various factors, including infection, inadequate healing, or excessive tension on the wound. Evisceration, on the other hand, involves the protrusion of intra-abdominal contents through the open wound, which can pose significant risks to the patient, including infection and organ damage. During the procedure, the surgical team inspects the suture line and the abdominal wall for any signs of infection, ensuring that the area is clean and suitable for reclosure. The old sutures are carefully removed to prepare the wound for new suturing. Any eviscerated abdominal contents are also examined and returned to the abdominal cavity to restore normal anatomy. The edges of the wound, which include the peritoneum, fascia, subcutaneous tissue, and skin, are meticulously trimmed to promote proper healing. Running sutures are then loosely placed along the entire length of the surgical wound, encompassing the peritoneum, fascia, and muscle layers. After all sutures are in place, they are tightened, and the knot is securely tied. Finally, the subcutaneous tissue and skin are closed over the abdominal wall, completing the procedure and aiming to restore the integrity of the abdominal wall.

1. Indications

The procedure described by CPT® Code 49900 is indicated in specific clinical scenarios where there is a need to address complications related to previous abdominal surgeries. The following conditions warrant the performance of this procedure:

  • Dehiscence The reopening of a surgical wound or incision that was previously closed, which may lead to complications if not addressed.
  • Evisceration The protrusion of intra-abdominal contents through an open wound, necessitating surgical intervention to prevent further complications and restore anatomical integrity.

2. Procedure

The procedure for secondary suture of the abdominal wall involves several critical steps to ensure proper closure and healing of the wound. Each step is essential for addressing the complications of dehiscence and evisceration:

  • Inspection of the Suture Line and Abdominal Wall The surgical team begins by thoroughly inspecting the suture line and the surrounding abdominal wall for any signs of infection. This step is crucial to ensure that the area is free from contaminants that could impede healing.
  • Removal of Old Sutures Once the inspection is complete, the old sutures that were used in the previous closure are carefully removed. This is necessary to prepare the wound for new suturing and to eliminate any potential sources of infection.
  • Inspection and Return of Eviscerated Contents If any abdominal contents have eviscerated, they are inspected for viability and then gently returned to the abdominal cavity. This step is vital to restore the normal anatomical position of the organs.
  • Trimming of Wound Edges The edges of the wound, including the peritoneum, fascia, subcutaneous tissue, and skin, are trimmed to promote a clean closure. This helps to ensure that the new sutures will hold effectively and that the wound will heal properly.
  • Placement of Running Sutures Running sutures are then loosely placed along the entire aspect of the surgical wound, encompassing the peritoneum, fascia, and muscle layers. This technique allows for even distribution of tension across the wound.
  • Tightening of Sutures After all sutures have been placed, they are tightened to secure the wound edges together. The knot is then tied to ensure that the sutures remain in place and provide adequate support to the healing tissue.
  • Closure of Subcutaneous Tissue and Skin Finally, the subcutaneous tissue and skin are closed over the abdominal wall, completing the procedure. This step is essential for protecting the underlying structures and facilitating the healing process.

3. Post-Procedure

Post-procedure care following the secondary suture of the abdominal wall is critical for ensuring proper recovery. Patients are typically monitored for signs of infection, such as increased redness, swelling, or discharge at the surgical site. Pain management may be provided as needed, and patients are advised on activity restrictions to avoid undue stress on the surgical site. Follow-up appointments are essential to assess the healing process and to remove sutures if non-absorbable materials were used. Additionally, patients may receive instructions on wound care to maintain cleanliness and promote healing.

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.)
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.
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).
