CPT® Code 63303

Vertebral corpectomy (vertebral body resection), partial or complete, for excision of intraspinal lesion, single segment; extradural, lumbar or sacral by transperitoneal or retroperitoneal approach

Vertebral corpectomy, as defined by CPT® Code 63303, is a surgical procedure that involves the resection of a vertebral body, which may be either partial or complete, specifically for the purpose of excising an intraspinal lesion. This procedure is performed on a single segment of the lumbar or sacral spine and is characterized by the removal of the vertebral body along with the intervertebral discs located above and below the affected vertebra. The lesions targeted in this procedure are located within the spinal canal but are positioned outside the dura mater, classifying them as extradural lesions. The surgical approach can be either transperitoneal, which involves an incision in the abdomen and entry into the peritoneal cavity, or retroperitoneal, which requires a flank incision to access the spine from an anterolateral position. During the procedure, careful dissection is performed to expose the affected vertebral segment while protecting vital structures in the surrounding area. The use of a surgical microscope aids in the precise removal of the intervertebral discs and the vertebral body, allowing for the identification and exploration of the lesion or tumor. Once the lesion is excised, additional procedures such as bone grafting and spinal instrumentation may be performed to ensure stability and support for the spine. This comprehensive approach is essential for addressing the underlying pathology while maintaining the structural integrity of the spinal column.
