CPT® Code 63270

The procedure described by CPT® Code 63270 involves a laminectomy specifically for the excision of an intraspinal lesion that is classified as non-neoplastic and located intradurally within the cervical 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 be attributed 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 cervical area, extending down to the spinous processes, and retracting the muscle 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. The surgeon then identifies the lesion within the dura mater, incises the dura over the lesion, and explores the extent of the lesion. A tissue sample may be collected for pathology examination to determine the nature of the lesion. Once identified, the lesion is meticulously dissected from surrounding tissues using an operating microscope and is removed once it is completely free. This procedure is critical for addressing non-neoplastic lesions that may cause neurological symptoms or complications due to their location within the spinal canal.
