CPT® Code 14020

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.
