Official Description

Adjacent tissue transfer or rearrangement, scalp, arms and/or legs; defect 10 sq cm or less

© 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 may arise from various causes, including traumatic wounds, lacerations, or surgically induced defects resulting from the excision of lesions or scars. In cases where a lesion or scar is present, the initial step involves excising this tissue to create a primary defect. The surgeon then evaluates the primary defect to determine the most suitable method for 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, each chosen based 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. This technique results in the formation of a secondary defect. To facilitate the movement of the skin flaps, the surrounding tissue is undermined, allowing for adequate mobilization. The elevated tissue is then transferred or rearranged to effectively cover the primary defect. In some instances, the transfer or rearrangement may also address the secondary defect, or alternatively, the secondary defect may be closed using a separately reportable skin graft. The dimensions of both the primary and secondary defects are measured to ascertain the size of the defect, which is critical for accurate coding. For defects measuring 10 square centimeters or less, the appropriate code to use is 14020, while for defects measuring between 10.1 square centimeters and 30 square centimeters, the code 14021 should be utilized.

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 cause damage to the skin and underlying tissues on the scalp, arms, or legs.
  • Lacerations - These are deep cuts or tears in the skin that may require surgical intervention to repair and restore the integrity of the affected area.
  • Surgically Created Defects - These defects may occur as a result of excising lesions or scars, necessitating reconstruction to achieve optimal cosmetic and functional outcomes.

2. Procedure

The procedure involves several critical steps to ensure effective tissue transfer or rearrangement:

  • Step 1: Evaluation of the Primary Defect - The surgeon begins by assessing the primary defect, which may be a result of trauma or surgical excision. This evaluation is crucial for determining the most appropriate technique for tissue transfer or rearrangement.
  • 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 the adjacent tissue transfer technique.
  • Step 3: Incision and Elevation of Tissue - Adjacent skin and subcutaneous tissue are incised and elevated, ensuring that one or more borders of the tissue remain attached. This step is essential for creating a secondary defect that will facilitate the transfer process.
  • Step 4: Undermining Surrounding Tissue - The surrounding tissue is undermined to allow for adequate mobilization of the skin flaps. This step enhances the flexibility and movement of the tissue being transferred.
  • Step 5: Transfer or Rearrangement of Tissue - The elevated tissue is then transferred or rearranged to cover the primary defect. The configuration of the transfer may also address the secondary defect, depending on the surgical plan.
  • Step 6: Closure of Secondary Defect - If the secondary defect is not covered by the transferred tissue, it may be closed using a separately reportable skin graft, ensuring that all defects are adequately addressed.
  • Step 7: Measurement of Defects - Finally, both the primary and secondary defects are measured to determine their sizes, which is essential for accurate coding and billing purposes.

3. Post-Procedure

Post-procedure care involves monitoring the surgical site for signs of infection, ensuring proper healing of the transferred tissue, and managing any discomfort. Patients may be advised on wound care techniques to maintain cleanliness and promote healing. Follow-up appointments are typically scheduled to assess the healing process and to address any complications that may arise. The expected recovery time may vary depending on the extent of the procedure and the individual patient's healing response.

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.
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)
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.)
