CPT® Code 63282

The procedure described by CPT® Code 63282 involves a laminectomy performed specifically for the biopsy or excision of an intraspinal neoplasm that is located intradurally and extramedullarily in the lumbar region. An intraspinal neoplasm refers to a tumor that is situated within the dura mater, which is the protective membrane surrounding the spinal cord, but is not directly within the spinal cord itself. These tumors can vary in nature, being benign, malignant, or of uncertain behavior. The laminectomy procedure entails making an incision in the skin over the lumbar area, where the tumor is identified. The surgical approach requires careful retraction of the muscles and removal of part or all of the lamina, which is the bony structure that covers the spinal canal. This allows for direct access to the dura mater, where the tumor is located. Once the tumor is accessed, a biopsy may be performed to obtain tissue for pathological examination, or the tumor may be excised if feasible. The procedure is conducted with precision, often utilizing an operating microscope to ensure that the tumor is completely separated from surrounding tissues before removal. After the tumor is excised, the dura mater is closed using sutures or a dural patch graft to restore the integrity of the protective covering of the spinal cord.
