CPT® Code 15610

The CPT® Code 15610 refers to the surgical procedure involving the delay of a flap or the sectioning of a flap, specifically at the scalp, arms, or legs. The term "delay of flap" describes a technique where a flap is partially divided to improve its blood supply before it is fully utilized in reconstruction. This staged approach, known as a delay maneuver, is crucial for enhancing vascular circulation at the recipient site, ensuring that the tissue remains viable and healthy during the healing process. On the other hand, "sectioning of flap" involves the complete transection of the flap, followed by its inset at the designated recipient site. This process includes the closure of the defect created by the flap's removal. In cases where a portion of the flap is not used, it is returned to the donor site. If the donor site has been previously closed with a skin graft, this graft may be removed and replaced with the remaining flap tissue. Should there be a need for additional coverage at the donor site, a separate skin graft or local flap can be applied. It is important to note that different codes are designated for similar procedures performed on various body parts, such as CPT® Code 15600 for the trunk, CPT® Code 15620 for the forehead, cheeks, chin, mouth, neck, axillae, genitalia, hands, or feet, and CPT® Code 15630 for the eyelids, nose, ears, or lips.
