Repair, complex, trunk; 1.1 cm to 2.5 cm

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A complex repair of a wound of the trunk involves a detailed and meticulous surgical procedure aimed at addressing wounds that are larger and more complicated than simple lacerations. This type of repair is necessary when the wound requires more than just a straightforward layered closure, indicating that the injury may involve deeper tissues or significant trauma. The procedure begins with the cleansing of the wound to prevent infection, followed by the administration of a local anesthetic to ensure patient comfort during the repair. Upon inspection, if the wound is determined to necessitate a complex approach, the surgeon may excise any existing scar tissue if the repair is for scar revision. In cases of traumatic lacerations or avulsions, the wound is thoroughly cleansed, and any foreign materials are removed. Debridement may be performed using sharp dissection techniques to remove devitalized tissue, which is crucial for promoting healing. The surgeon may also undermine the surrounding tissues to reduce tension on the wound edges, which is essential for optimal healing and minimizing scarring. Control of bleeding is achieved through chemical means or electrocautery, ensuring a clean surgical field. The closure technique varies based on the wound's location and nature; deeper layers may be closed with absorbable sutures, while superficial layers are typically closed with non-absorbable sutures. In some cases, retention sutures may be employed to hold the wound edges together without exerting tension, utilizing plastic or rubber tubing to facilitate this process. Additionally, stents may be used to maintain tissue alignment or keep an orifice open. Throughout the procedure, careful attention is paid to align the wound edges properly to prevent complications such as scar depression. This code, 13100, specifically applies to complex repairs of trunk wounds measuring between 1.1 cm and 2.5 cm in length, while additional codes are available for longer wounds.

1. Indications

The complex repair of a wound of the trunk is indicated for specific conditions that necessitate a more intricate surgical approach. These indications include:

  • Traumatic Lacerations Wounds resulting from accidents or injuries that require careful repair to restore function and appearance.
  • Avulsions Injuries where a portion of skin or tissue is torn away, necessitating complex closure techniques to ensure proper healing.
  • Scar Revision Procedures aimed at excising and repairing existing scars that may be unsightly or functionally impairing.

2. Procedure

The procedure for a complex repair of a wound of the trunk involves several critical steps, each designed to ensure optimal healing and aesthetic outcomes. The first step is the thorough cleansing of the wound to eliminate any contaminants and reduce the risk of infection. Following this, a local anesthetic is administered to ensure the patient remains comfortable throughout the procedure. Once the area is adequately anesthetized, the surgeon inspects the wound to determine the extent of the damage and whether a complex repair is warranted. If the procedure is for scar revision, the surgeon will excise the scar tissue to facilitate a fresh repair. In cases of traumatic lacerations or avulsions, the wound is meticulously cleaned, and any particulate matter is removed. Debridement may be performed using sharp dissection techniques to remove any non-viable tissue, which is essential for promoting healing. The surgeon may then undermine the surrounding tissues using scissors or a scalpel, which helps to minimize tension on the wound edges during closure. Bleeding control is a crucial aspect of the procedure, achieved through chemical agents or electrocautery to maintain a clear surgical field. The closure of the wound is tailored to its specific characteristics; the deepest layers may be closed with absorbable sutures, ensuring that the knots are buried to prevent irritation. The superficial layers are typically closed with non-absorbable sutures. In some instances, retention sutures may be utilized to hold the edges of the wound together without tension, which involves threading a short length of plastic or rubber tubing over each suture before tying them. Additionally, stents may be employed to maintain tissue alignment or keep an orifice open. Throughout the procedure, careful alignment of the wound edges is emphasized to prevent complications such as scar depression.

3. Post-Procedure

After the complex repair procedure is completed, post-procedure care is essential for optimal recovery. Patients are typically monitored for any signs of complications, such as infection or excessive bleeding. Instructions regarding wound care are provided, which may include keeping the area clean and dry, changing dressings as directed, and avoiding activities that could stress the repair site. Follow-up appointments are often scheduled to assess healing and remove any non-absorbable sutures if used. Patients may also receive guidance on managing pain and discomfort during the recovery period. It is crucial to adhere to all post-operative instructions to ensure proper healing and minimize the risk of complications.

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.
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).
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.)
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.
