CPT® Code 77059

Deleted

The CPT® Code 77059 refers to magnetic resonance imaging (MRI) performed on both breasts. This imaging technique is a noninvasive and non-radiating method that utilizes the magnetic properties of hydrogen atoms present in the body. When exposed to radiowaves within a strong magnetic field, the nuclei of these hydrogen atoms emit radiofrequency signals. A computer then processes these signals, converting the data into high-resolution, tomographic, three-dimensional sectional images of the internal structures of the breasts. This imaging is crucial for evaluating breast tissue and identifying any abnormalities. During the procedure, patients may be administered a sedative to help them remain still while lying on a motorized table that moves into the MRI machine, which is often referred to as a tunnel. Additionally, contrast material may be injected to enhance the quality of the images obtained, allowing for a more detailed examination of the breast tissue.
