CPT® Code 15770

The CPT® Code 15770 refers to a specific type of surgical graft known as a derma-fat-fascia graft. This composite graft is composed of three distinct layers: the epidermis, dermis, and fat, with fascia at the base. The graft is typically harvested from the ear, where the anatomical structure allows for the collection of these layers in a single piece. The process begins with the determination of the size and configuration of the graft, which is traced onto the donor site to ensure precision. Prior to excision, mattress sutures may be placed through the graft to stabilize the tissue layers, preventing them from separating during the harvesting process. Once the graft is excised, it is prepared for transfer to the recipient site, where it will be used to address soft tissue defects. The donor site is then closed primarily to promote healing. This type of grafting is often performed for reconstructive or aesthetic purposes, aiming to correct volume loss or contour deformities resulting from various conditions such as disease, trauma, tumor removal, or congenital defects. The procedure is integral in restoring the natural appearance and function of the affected area.
