CPT® Code 14302

Add-On Code

Adjacent tissue transfer or rearrangement, any area; each additional 30.0 sq cm, or part thereof (List separately in addition to code for primary procedure)

Adjacent tissue transfer or rearrangement is a surgical procedure aimed at covering a defect in the skin and underlying tissue. This defect may arise from various causes, including traumatic wounds, lacerations, or surgical excisions of lesions or scars. In cases where a lesion or scar is present, the first step involves excising the affected tissue. Following this, the primary defect is carefully evaluated 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 flaps, advancement flaps, or double pedicle flaps, each chosen based on the specific characteristics of the defect. During the procedure, adjacent skin and subcutaneous tissue are incised and elevated, ensuring that one or more borders of the tissue remain attached to the underlying structures. This action creates a secondary defect, which is then addressed by undermining the surrounding tissue to facilitate the mobilization of the skin flaps. The elevated tissue is subsequently transferred or rearranged to effectively cover the primary defect. In some instances, the configuration of the transfer may also address the secondary defect, or alternatively, the secondary defect may be closed using a separately reportable skin graft. To accurately report the procedure, the sizes of both the primary and secondary defects are measured. For defects measuring between 30.1 to 60.0 square centimeters, CPT® code 14301 is utilized, while CPT® code 14302 is designated for each additional 30.0 square centimeters or part thereof. This structured approach ensures that the surgical intervention is appropriately documented and billed, reflecting the complexity and extent of the tissue transfer or rearrangement performed.
