Formation of direct or tubed pedicle, with or without transfer; scalp, arms, or legs

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 15572 refers to the formation of a direct or tubed pedicle flap, specifically for use on the scalp, arms, or legs. This procedure is a critical component in reconstructive surgery, particularly in the management of non-adjacent defects that require coverage. A pedicle flap is a type of tissue transfer that maintains its blood supply from the donor site, allowing for better healing and integration at the recipient site. In this context, a direct pedicle flap is created and immediately transferred to the recipient site during the same surgical session, with the donor site being approximated to the recipient site to facilitate healing. Conversely, a tubed pedicle flap involves sewing the lateral edges of the flap together to form a tube, which can then be transferred to the recipient site. The procedure involves careful planning of the flap's size and shape, followed by an incision at the donor site to raise a full-thickness flap. This flap is then sutured to the recipient site in multiple layers to ensure stability and proper healing. The donor site is subsequently closed with sutures, although in some cases, a separate skin graft or local flap may be necessary to adequately close the donor site. This code is specifically utilized for flaps transferred to the scalp, arms, or legs, distinguishing it from other codes that apply to different anatomical sites.

1. Indications

The procedure associated with CPT® Code 15572 is indicated for the following conditions:

  • Non-adjacent defects that require coverage on the scalp, arms, or legs.
  • Reconstructive needs following trauma, surgical excision, or congenital defects in the specified anatomical areas.
  • Skin loss due to various etiologies, necessitating the use of a pedicle flap for effective closure and healing.

2. Procedure

The procedure for CPT® Code 15572 involves several critical steps to ensure successful flap formation and transfer:

  • Step 1: Planning the Flap The surgeon begins by determining the appropriate size and configuration of the flap based on the defect's dimensions and location. This planning is essential to ensure that the flap will adequately cover the defect while maintaining its blood supply.
  • Step 2: Incision at the Donor Site An incision is made at the donor site, which is the area from which the flap will be harvested. This incision is carefully designed to allow for the full-thickness flap to be raised while preserving the underlying blood vessels that will supply the flap.
  • Step 3: Raising the Flap The full-thickness flap is then raised from the donor site. This involves dissecting the tissue carefully to ensure that the blood supply remains intact. The flap must be mobilized adequately to allow for transfer to the recipient site.
  • Step 4: Transferring the Flap Once the flap is raised, it is transferred to the recipient site. For a direct pedicle flap, this transfer occurs immediately, with the donor site approximated to the recipient site. In the case of a tubed pedicle flap, the lateral edges of the flap are sewn together to form a tube before transfer.
  • Step 5: Suturing the Flap The flap is sutured to the recipient site in multiple layers to ensure proper alignment and stability. This layered approach helps to secure the flap and promotes optimal healing.
  • Step 6: Closing the Donor Site After the flap has been successfully transferred and secured, the donor site is closed with sutures. In some instances, if the donor site cannot be closed adequately, a separately reportable skin graft or local flap may be required to achieve closure.

3. Post-Procedure

Post-procedure care for patients undergoing the formation of a direct or tubed pedicle flap includes monitoring the flap for signs of viability, such as color, temperature, and capillary refill. Patients are typically advised to keep the area clean and dry, and to follow specific instructions regarding activity restrictions to promote healing. Follow-up appointments are essential to assess the healing process and to address any complications that may arise. Additionally, the surgeon may provide guidance on wound care and signs of infection to watch for during the recovery period.

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.
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.
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).
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.)
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
