CPT® Code 63283

The procedure described by CPT® Code 63283 involves a laminectomy performed specifically for the biopsy or excision of an intraspinal neoplasm located intradurally within the sacral region. An intraspinal neoplasm refers to a tumor that can be benign, malignant, or of uncertain behavior, and is situated within the dura mater, which is the protective covering of the spinal cord. In this case, the tumor is positioned outside the spinal cord itself, classified as extramedullary, meaning it does not invade the spinal cord tissue. The surgical approach begins with an incision in the skin over the sacral area, allowing access to the underlying structures. The procedure entails careful dissection to expose the lamina, which is the bony arch of the vertebra, and the facet joint. Utilizing a bone drill, the surgeon removes part or all of the lamina to gain access to the dura mater and the tumor. Once the tumor is located, the dura is incised, and the tumor is assessed to confirm it lies outside the spinal cord. A biopsy may be taken for pathological analysis, and if the tumor is amenable to excision, it is meticulously dissected from surrounding tissues, often with the aid of an operating microscope, before being removed. The procedure concludes with the closure of the dura, either with sutures or a dural patch graft, ensuring the integrity of the protective covering of the spinal cord is maintained.
