CPT® Code 63267

The procedure described by CPT® Code 63267 involves a laminectomy performed specifically for the excision or evacuation of a non-neoplastic intraspinal lesion located in the lumbar region. Non-neoplastic intraspinal lesions can arise from various causes, including infectious agents such as tuberculosis, syphilis, cytomegalovirus, herpes simplex virus, bacteria, or parasites. Additionally, non-infectious lesions may occur due to conditions like sarcoidosis, multiple sclerosis, or systemic lupus erythematosus. Inflammatory lesions, which can result from idiopathic necrotizing processes or radiation myelopathy, also fall under this category. During the laminectomy, the surgeon makes an incision in the skin over the lumbar area, extending down to the spinous processes to access the spine. The procedure involves retracting the muscles away from the lamina and facet joint, followed by the removal of part or all of the lamina using a bone drill. This allows for exposure of the spinal cord and identification of the lesion. The surgeon then explores the extent of the lesion, ensuring it is limited to the tissue outside the dura mater. A tissue sample may be collected for pathology examination, and the lesion is meticulously dissected from surrounding tissues, potentially utilizing an operating microscope for enhanced visualization. Once fully detached, the lesion is either excised or evacuated using suction. This procedure is critical for addressing various non-neoplastic conditions affecting the lumbar spine.
