Breast reconstruction
About 11970: Tissue expander to implant exchange
Reports exchange of a tissue expander for a permanent implant, commonly during the later stage of breast reconstruction after mastectomy.
This code describes the operative exchange of a temporary tissue expander for a permanent implant. It is commonly used by plastic surgeons for the later stage of breast reconstruction after mastectomy, once expansion is complete. The exchange includes removing the expander and placing the permanent implant; it is distinct from an operation that only inserts an expander or only removes one.
Select the code when the operative report supports an expander-to-implant exchange, and document the reconstruction site, laterality, and work performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. A bilateral procedure reported with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
