CPT® Code 21248

The procedure described by CPT® Code 21248 involves the surgical reconstruction of the mandible or maxilla using an endosteal implant, which can be in the form of a blade or cylinder. This specific code is designated for partial reconstructions, distinguishing it from CPT® Code 21249, which is used for complete reconstructions. During this procedure, the physician makes an incision in the area of the jaw where teeth are absent, allowing for direct access to the underlying bone. The surgical approach aims to expose the bone as thoroughly as possible to facilitate the precise placement of the implant. The endosteal implant is then inserted into pre-drilled holes that have been carefully prepared in the bone. Following the insertion of the implant, the surrounding tissue is meticulously arranged and sutured around the implant post, ensuring stability and proper healing. In the case of blade-style implants, the tissue is sutured around the implant, while for cylindrical implants, the tissue is closed over the top of the posts. It is important to note that a subsequent surgical procedure will be required to attach the dental prosthesis to the implant, completing the reconstruction process. Finally, all incisions made during the procedure are closed to promote healing and recovery.
