CPT® Code 70552

Magnetic resonance imaging (MRI) of the brain, specifically coded as CPT® 70552, is a sophisticated imaging technique that utilizes the magnetic properties of hydrogen atoms within the body to create detailed images of the brain and brain stem. This noninvasive procedure does not involve radiation, making it a safer alternative for patients requiring diagnostic imaging. During the MRI process, the patient is positioned on a motorized table that moves into a large cylindrical scanner, which houses a powerful magnet. The magnetic field generated by the scanner aligns the hydrogen atoms in the body. Following this alignment, radiowaves are transmitted into the magnetic field, causing the protons in various tissues to emit specific radiofrequency signals. These signals are captured and processed by a computer, which constructs high-resolution, three-dimensional images of the brain. MRI of the brain is instrumental in diagnosing a wide range of conditions, including tumors, cysts, and other masses, as well as swelling, infections, and vascular disorders such as aneurysms and intracranial hemorrhages. It is also valuable in assessing diseases of the pituitary gland, strokes, developmental anomalies, hydrocephalus, and chronic conditions affecting the central nervous system, including headaches and multiple sclerosis. The use of contrast material, such as gadolinium, enhances the imaging quality and allows for better visualization of certain abnormalities. When contrast is administered prior to the imaging, the procedure is reported using code 70552. In contrast, if the MRI is performed without contrast, code 70551 is used, and if it is initially done without contrast followed by the use of contrast for additional imaging, code 70553 is applicable. The physician is responsible for reviewing the MRI results, identifying any abnormalities, and providing a comprehensive written interpretation of the findings.
