CPT® Code 15570

The CPT® Code 15570 refers to the formation of a direct or tubed pedicle flap, which can be performed with or without the transfer of the flap to another site on the trunk. A pedicle flap is a type of surgical procedure that involves creating a full-thickness flap of tissue that remains attached to its original blood supply at the donor site. This technique is particularly useful for covering non-adjacent defects, as it allows for the transfer of healthy tissue to areas that require reconstruction. In the case of a direct pedicle flap, the flap is developed and immediately transferred to the recipient site during the same surgical session, with the donor site being approximated to the recipient site to facilitate healing. Conversely, a tubed pedicle flap involves sewing the lateral edges of the flap together to form a tube, which is then transferred to the recipient site. The procedure includes determining the size and configuration of the flap, incising the donor site, and raising a full-thickness flap, which is then sutured to the recipient site in multiple layers. After the flap is secured, the donor site is closed with sutures. In some cases, a separately reportable skin graft or local flap may be necessary to adequately close the donor site. This code is specifically used for the transfer of a flap to the trunk or for the formation of a tubed flap on the trunk that will be transferred to another site later.
