The procedure described by CPT® Code 15757 involves the use of a free skin flap with microvascular anastomosis, which is a surgical technique employed to repair defects in the skin or underlying tissues. This procedure is typically performed under general anesthesia to ensure the patient is completely unconscious and free from pain during the operation. The free skin flap is a section of skin and underlying tissue that is detached from its original site and relocated to a different area of the body where it is needed for reconstruction. The microvascular anastomosis aspect of the procedure is critical, as it involves the precise connection of blood vessels and nerves from the donor tissue to the recipient site, ensuring that the transplanted flap receives adequate blood supply and nerve function post-surgery. The process begins with the careful preparation of the donor area, followed by the removal of the skin flap, which is then sutured into the defect area. The use of half-mattress sutures helps secure the flap in place. To facilitate the anastomosis, microscopy may be employed to enhance the surgeon's view of the small blood vessels and nerves, allowing for meticulous connection. The injection of fluorescent dye serves as a diagnostic tool to confirm the successful joining of these vessels. After ensuring proper vascularization, the wound is sutured closed, and a dressing is applied to protect the area. Additionally, splinting may be utilized to minimize the risk of shrinkage of the skin flap during the healing process. The donor site is also closed and dressed to promote healing and minimize complications.

The procedure associated with CPT® Code 15757 is indicated for various conditions where skin and underlying tissue defects need reconstruction. These indications may include:
The procedure for CPT® Code 15757 involves several critical steps to ensure successful reconstruction of the defect area. These steps include:
Post-procedure care for patients undergoing CPT® Code 15757 includes monitoring the surgical sites for signs of infection, ensuring proper blood flow to the skin flap, and managing pain. Patients may be advised to keep the area clean and dry, and to follow specific instructions regarding dressing changes. It is also important to monitor for any signs of complications, such as flap failure or necrosis. Follow-up appointments will be necessary to assess healing and to remove sutures as needed. Additionally, splinting may be recommended to minimize movement and reduce the risk of skin flap shrinkage during the initial healing phase.
