CPT® Code 72255

Myelography is a specialized diagnostic imaging procedure that involves the use of contrast material to visualize the spinal cord and its surrounding structures. This procedure is performed by injecting a contrast agent into the subarachnoid space, which is the area surrounding the spinal cord. The injection is typically done using a needle that is carefully placed into the spinal canal. Once the contrast material is introduced, real-time fluoroscopic X-ray imaging is utilized to monitor the flow of the contrast as it moves through the subarachnoid space. This allows the radiologist to assess various components of the spinal anatomy, including the spinal cord, spinal canal, nerve roots, meninges, and blood vessels. The dynamic imaging provided during the procedure enables the identification of abnormalities such as intervertebral disc herniation, meningeal inflammation, spinal stenosis, tumors, and other lesions that may arise from infections or prior trauma. In addition to real-time imaging, permanent X-ray images may also be captured for further analysis. Myelography can be performed on different regions of the spine, with specific CPT® codes assigned for cervical, thoracic, and lumbosacral myelography, as well as for examinations involving multiple spinal regions.
