Tissue expanders are used when there is insufficient skin left on the chest following a mastectomy to provide adequate coverage of a breast implant. Tissue expanders are inflatable breast implants that have silicone outer shells and either an internal valve or external port to allow for saline fluid injections that stretch the skin over time. Once the skin has been stretched sufficiently, the tissue expander is removed and replaced with a permanent breast implant. This type of breast reconstruction is known as staged reconstruction.
The initial insertion of a tissue expander is assigned to CPT code 19357.
