CPT® Code 19357

The CPT® Code 19357 refers to the procedure of tissue expander placement in breast reconstruction, which is a critical step in the process of restoring breast shape and volume following a mastectomy. This procedure involves the surgical insertion of a tissue expander, a device designed to gradually stretch the skin and underlying tissues of the breast area. The physician begins by making an incision at the site of a previous mastectomy, which allows access to the chest wall. Underneath the remaining chest wall tissue, a pocket is created to accommodate the tissue expander. This expander is then inserted into the pocket, where it can be inflated over time to achieve the desired breast size. The inflation process involves the injection of saline into the expander, which can either remain inside the body or have its inflation point brought outside for easier access. The gradual expansion of the tissue expander is essential, as it allows the skin and tissue to adapt and stretch, preparing for the eventual placement of a permanent implant. Once the desired size is achieved, the tissue expander is typically removed in a subsequent surgical procedure, at which point a permanent breast implant may be placed. This method not only aids in the physical reconstruction of the breast but also plays a significant role in the psychological and emotional recovery of patients following breast cancer treatment.
