Reconstructive surgery
About 11971: Tissue expander removal without implant placement
Removal of a temporary tissue expander without placing an implant, commonly during breast reconstruction when expansion is discontinued or the device must be removed.
The surgeon removes a temporary tissue expander from its reconstructive pocket without inserting a permanent implant during that operation. Plastic and reconstructive surgeons most often perform this service during staged breast reconstruction, such as when an expander is removed because of infection, exposure, or a decision not to proceed with implant reconstruction. Tissue expanders used at other reconstructive sites may also be removed under this code when the service fits the code’s scope.
Report 11971 when the operative service removes the expander and no implant is inserted; an expander-to-implant exchange is a different service. The operative report should identify the site and side, the expander removal, and whether an implant was placed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
