CPT® Code 72240

Myelography is a specialized diagnostic imaging procedure that involves the use of contrast material to visualize the spinal cord and its surrounding structures. This technique is performed by injecting a contrast agent into the subarachnoid space, which is the area surrounding the spinal cord. The procedure is conducted under radiological supervision, utilizing real-time fluoroscopic X-ray imaging to monitor the flow of the contrast material. The radiologist carefully introduces a needle into the spinal canal to facilitate the injection of the contrast agent. As the contrast material disperses through the subarachnoid space, it enhances the visibility of critical anatomical structures, including the spinal cord, spinal canal, nerve roots, meninges, and blood vessels. This real-time imaging allows for immediate assessment of any abnormalities. Additionally, permanent X-ray images may be captured during the procedure for further analysis. Myelography is particularly useful in diagnosing various spinal conditions, such as intervertebral disc herniation, meningeal inflammation, spinal stenosis, tumors, and other lesions that may arise from infections or prior trauma. For coding purposes, CPT® Code 72240 specifically refers to myelography of the cervical spine, while other codes are designated for thoracic, lumbosacral, and multi-region examinations.
