CPT® Code 76800

An ultrasound examination of the spinal canal and its contents, designated by CPT® Code 76800, is a diagnostic imaging procedure that utilizes high-frequency sound waves to visualize internal structures of the body. This non-invasive technique is particularly effective in assessing the spinal canal in newborns and infants, where the spine has minimal ossification, allowing for clearer imaging. The ultrasound works by emitting sound waves that penetrate the body and reflect off various tissues, with the returning echoes being captured and converted into visual images displayed on a monitor. This method is advantageous in pediatric patients due to the shorter distance between the skin surface and the spinal subarachnoid space, facilitating better visualization. While spinal ultrasound can also be employed intraoperatively in adults and older children, its diagnostic efficacy is limited in these populations. During the procedure, the patient is typically positioned prone, with the neck flexed to optimize access to the spinal area. Acoustic coupling gel is applied to the skin to enhance sound wave transmission. A linear probe is then used to examine the spinal canal and its contents in both sagittal and axial planes, ensuring a comprehensive evaluation along the entire length of the spine. Following the examination, the physician analyzes the captured images and provides a detailed written interpretation of the findings.
