CPT® Code 15738

The procedure described by CPT® Code 15738 involves the use of a muscle, myocutaneous, or fasciocutaneous flap specifically for the lower extremity. This surgical technique is employed to repair defects in the lower leg or foot area, where tissue loss may have occurred due to trauma, surgery, or other medical conditions. The flap is created by harvesting a section of muscle along with its associated skin and fascia from a donor site, which is typically located in the same lower extremity. Once the flap is prepared, it is rotated into position to cover the defect, ensuring that the vascular supply is maintained to promote healing. The surgeon then sutures the flap securely in place, and the donor site is closed, either with sutures or, if necessary, a separate skin graft. It is important to note that if a skin graft is required to close the donor site, this procedure should be reported separately using the appropriate CPT® code. This technique is critical in reconstructive surgery, as it helps restore both function and aesthetics to the affected area.
