Official Description

Adjacent tissue transfer or rearrangement, scalp, arms and/or legs; defect 10.1 sq cm to 30.0 sq cm

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An adjacent tissue transfer or rearrangement is a surgical procedure aimed at addressing defects located on the scalp, arms, and/or legs. These defects can arise from various causes, including traumatic wounds, lacerations, or surgical excisions of lesions or scars. The procedure begins with the evaluation of the primary defect to determine the most suitable method of tissue transfer or rearrangement. Various techniques may be employed, such as Z-plasty, W-plasty, V-Y plasty, rotation flap, advancement flap, or double pedicle flap, depending on the specific characteristics of the defect. During the procedure, adjacent skin and subcutaneous tissue are carefully incised and elevated, ensuring that one or more borders of the tissue remain attached to maintain blood supply. This action creates a secondary defect, which is then addressed by undermining the surrounding tissue to facilitate the mobilization of the skin flaps. The tissue is subsequently transferred or rearranged to effectively cover the primary defect. In some cases, the transfer may also cover the secondary defect, or alternatively, the secondary defect may be closed using a separately reportable skin graft. Accurate measurement of both the primary and secondary defects is essential to determine the appropriate coding, with CPT® Code 14021 specifically designated for defects measuring between 10.1 square centimeters and 30.0 square centimeters.

1. Indications

The procedure of adjacent tissue transfer or rearrangement is indicated for the following conditions:

  • Traumatic Wounds - These are injuries resulting from accidents or external forces that create defects in the skin and underlying tissues.
  • Lacerations - These are deep cuts or tears in the skin that may require surgical intervention to repair and restore function and appearance.
  • Surgically Created Defects - These defects may arise from the excision of lesions or scars, necessitating reconstruction to achieve optimal healing and aesthetic results.

2. Procedure

The procedure involves several critical steps to ensure effective reconstruction of the defect:

  • Step 1: Evaluation of the Primary Defect - The surgeon begins by assessing the primary defect to determine the most appropriate method of tissue transfer or rearrangement. This evaluation considers the size, location, and characteristics of the defect.
  • Step 2: Excision of Lesion or Scar - If a lesion or scar is present, it is excised to create a clean primary defect that can be addressed through tissue transfer.
  • Step 3: Incision and Elevation of Adjacent Tissue - Adjacent skin and subcutaneous tissue are incised and elevated, ensuring that one or more borders remain attached to preserve blood supply. This step is crucial for the viability of the transferred tissue.
  • Step 4: Creation of a Secondary Defect - The elevation of the tissue creates a secondary defect, which will also need to be addressed during the procedure.
  • Step 5: Undermining Surrounding Tissue - The surrounding tissue is undermined to allow for adequate mobilization of the skin flaps, facilitating their movement to cover the primary defect.
  • Step 6: Transfer or Rearrangement of Tissue - The mobilized tissue is then transferred or rearranged to cover the primary defect effectively. The configuration may also address the secondary defect, or it may be closed with a separately reportable skin graft if necessary.
  • Step 7: Measurement of Defects - Finally, both the primary and secondary defects are measured to determine the appropriate coding for the procedure, ensuring accurate documentation and billing.

3. Post-Procedure

Post-procedure care involves monitoring the surgical site for signs of infection, ensuring proper healing of the tissue transfer, and managing any discomfort. Patients may be advised on activity restrictions to promote optimal recovery. Follow-up appointments are essential to assess the healing process and to address any complications that may arise. The surgeon will provide specific instructions regarding wound care and any necessary follow-up treatments.

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)
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.)
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.
SG Ambulatory surgical center (asc) facility service
RT Right side (used to identify procedures performed on the right side of the body)
LT Left side (used to identify procedures performed on the left side of the body)
XP Separate practitioner, a service that is distinct because it was performed by a different practitioner
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.
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 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.
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.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 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).
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).
