CPT® Code 72147

Magnetic resonance imaging (MRI) is a sophisticated imaging technique utilized to visualize the thoracic spinal canal and its contents. This noninvasive procedure employs the magnetic properties of hydrogen nuclei present in the body, allowing for detailed imaging without the use of ionizing radiation. During an MRI, a powerful magnetic field is generated, which causes the hydrogen atoms in the body to align with the magnetic field. Subsequently, radiowaves are transmitted into this magnetic field, prompting the protons within the hydrogen nuclei to emit specific radiofrequency signals. These signals are captured by a computer, which processes the data to produce high-resolution tomographic images in three-dimensional slices. The patient undergoing this procedure is positioned on a motorized table that moves into a large MRI scanner, often referred to as a tunnel, which houses the magnet. MRI scans of the thoracic spine are typically indicated when conservative treatments for back or neck pain have proven ineffective, prompting the need for further investigation or consideration of more aggressive treatment options. In the context of CPT® Code 72147, the procedure involves the administration of contrast material, which enhances the visibility of the spinal structures, allowing for a more comprehensive assessment. This is in contrast to CPT® Code 72146, where no contrast medium is utilized. The physician analyzes the resulting images to identify various conditions that may be contributing to the patient's symptoms, including abnormal spinal alignment, vertebral body diseases or injuries, intervertebral disc issues such as herniation or degeneration, the adequacy of the spinal canal for accommodating the spinal cord and nerve roots, and any signs of nerve compression or inflammation, as well as monitoring for changes post-surgery.
