CPT® Code 11970

The procedure described by CPT® Code 11970 involves the surgical replacement of a tissue expander with a permanent implant. A tissue expander is a device used in reconstructive surgery to stretch the skin and create additional tissue for later use, often in breast reconstruction. In this procedure, the physician first deflates the existing tissue expander to facilitate its removal. An incision is made at the site of the expander, allowing the surgeon to carefully extract the device. Once the tissue expander is removed, a permanent implant, which is selected based on the appropriate size for the patient's needs, is inserted into the same location. The implant is then stabilized to ensure proper positioning and function. Finally, the incision is closed, completing the procedure. This code is distinct from CPT® Code 11971, which involves the removal of a tissue expander without the insertion of a permanent implant or another expander, highlighting the specific nature of the surgical intervention associated with CPT® Code 11970.
