CPT® Code 63286

The procedure described by CPT® Code 63286 involves a laminectomy performed specifically for the biopsy or excision of an intraspinal neoplasm located intradurally and intramedullarily within the thoracic region of the spinal cord. An intraspinal neoplasm refers to a tumor that may be benign, malignant, or of uncertain behavior, situated within the protective dura mater of the spinal cord and extending into the spinal cord tissue itself. This procedure is critical for diagnosing and treating tumors that do not extend beyond the dura into the extradural tissues. The surgical approach begins with an incision in the skin over the thoracic area, followed by careful dissection to access the spinal structures. The lamina, which is a bony structure of the vertebra, is partially or completely removed to expose the spinal cord and the tumor. The tumor is then identified, and a biopsy may be taken for pathological examination. Depending on the tumor's characteristics, it may be excised entirely, requiring meticulous dissection to ensure complete removal while preserving surrounding tissues. The procedure concludes with the closure of the dura mater, which may involve sutures or a dural patch graft to ensure proper healing and protection of the spinal cord.
