CPT® Code 72142

Magnetic resonance imaging (MRI) is a sophisticated imaging technique utilized to visualize the cervical 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 the MRI process, a powerful magnetic field is generated, which aligns the hydrogen atoms in the body. Subsequently, radiowaves are transmitted through this magnetic field, causing the protons in various tissues 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 of the cervical spine is typically indicated when conservative treatments for neck or back pain have failed, or when further evaluation is necessary following surgical interventions. The use of contrast material in CPT® Code 72142 enhances the visibility of the spinal structures, allowing for a more comprehensive assessment of potential abnormalities, such as misalignment of the spine, vertebral body diseases or injuries, intervertebral disc issues, and nerve-related conditions. This detailed imaging aids physicians in correlating the findings with the patient's clinical symptoms, thereby facilitating informed decision-making regarding further treatment options.
