CPT® Code 63280

The procedure described by CPT® Code 63280 involves a laminectomy performed specifically for the biopsy or excision of an intraspinal neoplasm that is located intradurally and extramedullarily in the cervical region. An intraspinal neoplasm refers to a tumor that can be benign, malignant, or of uncertain behavior, situated within the protective dura mater of the spinal cord but not invading the spinal cord itself. This distinction is crucial as it influences the surgical approach and potential outcomes. During the procedure, the surgeon makes an incision in the skin over the cervical area where the tumor is located, extending down to the spinous processes to access the spine. The muscle tissue is carefully retracted to expose the lamina and facet joint, allowing for the use of a bone drill to remove part or all of the lamina, which is the bony arch of the vertebra. This step is essential for exposing the spinal cord and the tumor within the dura mater. Once the tumor is identified, the dura is incised, and the tumor is assessed to confirm that it lies outside the spinal cord. A biopsy may be taken for pathological examination, and if the tumor is amenable to excision, it is meticulously dissected from surrounding tissues, often with the aid of an operating microscope to ensure precision. After complete removal, the dura is closed with sutures or a dural patch graft to restore the integrity of the protective covering of the spinal cord.
