CPT® Code 63278

The procedure described by CPT® Code 63278 involves a laminectomy performed specifically for the biopsy or excision of an intraspinal neoplasm located in the extradural space of the sacral region. An intraspinal neoplasm refers to a tumor that can be either benign, malignant, or of uncertain behavior, which means its potential for growth and spread is not clearly defined. In this surgical intervention, the neoplastic tumor is situated outside the dura mater, the protective membrane surrounding the spinal cord. The procedure begins with an incision made in the skin over the appropriate spinal region, which can include the cervical, thoracic, lumbar, or sacral areas, depending on the tumor's location. The incision is deepened to reach the spinous processes, which are bony protrusions along the spine. During the operation, the muscles are carefully retracted to expose the lamina and facet joint, which are parts of the vertebrae. A bone drill is then utilized to remove a portion or the entirety of the lamina, allowing access to the spinal cord. Once the spinal cord is exposed, the surgeon identifies the tumor and assesses its extent, confirming that it is confined to the tissue outside the dura mater. A tissue sample may be collected for pathology examination to determine the nature of the tumor. Following the biopsy, the surgeon may either close the surgical site or proceed to excise the tumor. If excision is possible, the tumor is meticulously dissected from the surrounding tissues, often with the aid of an operating microscope to ensure precision. The procedure concludes with the complete removal of the tumor, if feasible, ensuring that all affected tissue is excised to minimize the risk of recurrence.
