CPT® Code 62303

Myelography is a specialized imaging technique utilized to obtain detailed visualizations of the spinal canal, spinal cord, and spinal nerve roots. This procedure employs real-time fluoroscopy in conjunction with X-ray imaging to create comprehensive images that assist in diagnosing various spinal conditions. Myelography is particularly valuable in identifying issues such as intervertebral disc herniation, spinal stenosis, tumors, infections, inflammation, and other lesions that may arise due to disease or trauma. During the procedure, the patient is typically positioned either lying on their abdomen or side to facilitate access to the lumbar region of the spine. A spinal needle is carefully advanced into the spinal canal under fluoroscopic guidance until cerebrospinal fluid (CSF) is observed flowing freely, indicating proper placement. Subsequently, a non-ionic contrast material is injected into the subarachnoid space through the needle, allowing for enhanced visualization of the spinal structures. The procedure involves tilting the procedure table to enable the contrast dye to flow throughout the subarachnoid space, with fluoroscopy monitoring the flow and X-rays being taken to document any abnormalities. Upon completion of the myelography, the table is returned to a horizontal position, and the patient is permitted to assume a comfortable posture. It is important to note that different CPT® codes are designated for myelography based on the specific spinal region being examined: code 62302 for the cervical region, code 62303 for the thoracic region, code 62304 for the lumbosacral area, and code 62305 when two or more spinal areas are evaluated.
