CPT® Code 62305

Myelography via lumbar injection, including radiological supervision and interpretation; 2 or more regions (eg, lumbar/thoracic, cervical/thoracic, lumbar/cervical, lumbar/thoracic/cervical)

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 to flow freely, indicating proper placement. Subsequently, a contrast material, specifically a non-ionic dye, is injected into the subarachnoid space through the needle. This contrast agent enhances the visibility of the spinal structures during imaging. The procedure involves tilting the procedure table to allow the contrast dye to flow throughout the subarachnoid space, which is monitored in real-time using fluoroscopy. X-rays are then obtained to document any abnormalities present. 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 CPT® Code 62305 is specifically designated for instances where two or more regions of the spine are examined, distinguishing it from codes that pertain to single regions.
