CPT® Code 63273

The procedure described by CPT® Code 63273 involves a laminectomy performed specifically for the excision of a non-neoplastic intraspinal lesion located within the dura mater in the sacral 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. The laminectomy procedure entails making an incision in the skin over the affected area, which may be in the cervical, thoracic, lumbar, or sacral regions, and extending this incision down to the spinous processes. The muscle is then retracted to access the lamina and facet joint. A bone drill is utilized to remove part or all of the lamina, allowing for exposure of the spinal cord. Once the lesion is identified within the dura mater, the dura is incised, and the lesion is explored to determine its extent. A tissue sample may be collected for pathology examination. The lesion is meticulously dissected from surrounding tissues using an operating microscope, and once fully detached, it is removed. This procedure is critical for addressing non-neoplastic lesions that may cause neurological symptoms or complications.
