Official Description

Repair, complex, scalp, arms, and/or legs; 1.1 cm to 2.5 cm

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Complex repair is a surgical procedure that involves the closure of a wound requiring more than one layered closure technique. This type of repair is typically necessary for wounds that are more extensive or complicated, such as those that may involve scar revision, debridement, extensive undermining, or the use of stents and retention sutures. The procedure is performed under local anesthesia to ensure patient comfort while the physician meticulously cleans the wound site. The complex repair process involves addressing the subcutaneous tissue, dermis, and epidermis, particularly in areas such as the scalp, arms, and/or legs. For the closure, dissolving sutures are often utilized for the deeper layers beneath the skin, promoting healing without the need for suture removal. In instances where multiple wounds of the same complexity are present in the same anatomical area, the total lengths of these similar wounds are combined to determine the appropriate coding. Specifically, CPT® Code 13120 is designated for repairs measuring between 1.1 cm and 2.5 cm, while additional codes are available for larger repairs, ensuring accurate representation of the complexity and extent of the surgical intervention.

1. Indications

Complex repair procedures are indicated for various conditions and scenarios where a simple closure is insufficient. The following are explicitly provided indications for performing a complex repair:

  • Extensive Wounds Wounds that require more than one layered closure due to their size or complexity.
  • Scar Revision Situations where existing scars need to be revised for cosmetic or functional improvement.
  • Debridement Cases where tissue removal is necessary to promote healing or prevent infection.
  • Extensive Undermining Wounds that necessitate the undermining of tissue to allow for proper closure.
  • Use of Stents or Retention Sutures Instances where additional support is required to maintain the integrity of the closure.

2. Procedure

The procedure for a complex repair involves several critical steps that ensure the effective closure of the wound. Each step is essential for achieving optimal healing and aesthetic outcomes.

  • Step 1: Preparation The procedure begins with the patient being positioned comfortably, and the area surrounding the wound is cleaned thoroughly to minimize the risk of infection. Local anesthesia is administered to ensure the patient remains comfortable throughout the procedure.
  • Step 2: Wound Assessment The physician assesses the wound to determine the extent of the damage and the complexity involved. This assessment helps in planning the repair strategy, including the need for scar revision or debridement.
  • Step 3: Complex Repair Execution The physician performs the complex repair by carefully closing the wound in layers. This may involve suturing the subcutaneous tissue, dermis, and epidermis, ensuring that each layer is properly aligned and secured. Techniques such as undermining may be employed to facilitate closure without tension.
  • Step 4: Suture Application Dissolving sutures are used for the deeper layers beneath the skin, which will gradually dissolve as the tissue heals. This choice of sutures eliminates the need for a follow-up visit for suture removal, enhancing patient convenience.
  • Step 5: Final Inspection Once the repair is complete, the physician inspects the wound to ensure that it is properly closed and that there are no complications. The area is then dressed appropriately to protect the wound during the initial healing phase.

3. Post-Procedure

After the complex repair procedure, patients are typically advised on post-procedure care to promote healing and prevent complications. This may include instructions on keeping the wound clean and dry, monitoring for signs of infection, and avoiding strenuous activities that could stress the repair site. Patients may also be informed about the expected recovery timeline and any follow-up appointments necessary to assess healing progress. It is crucial for patients to adhere to these guidelines to ensure optimal outcomes and minimize the risk of complications.

This is a primary code that can be used with these additional add-on codes.

20701 Add-on Code MPFS Status: Active Code APC N Removal of drug-delivery device(s), deep (eg, subfascial) (List separately in addition to code for primary procedure)
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).
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.
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.)
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
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.
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
