CPT® Code 77057

This CPT® code 77057 refers to a bilateral screening mammography procedure, which involves taking two views of each breast. Mammography is a specialized form of radiographic imaging that utilizes low-dose ionizing radiation to create images of the breast tissue. The technique is designed to detect early signs of breast cancer in women who do not exhibit any symptoms or palpable masses. During the procedure, the breast is placed between two plates on a mammography machine, which is specifically designed for this purpose. This compression serves multiple functions: it evens out the dense breast tissue, reduces the thickness of the breast, and stabilizes it to minimize movement, thereby enhancing the quality of the images obtained. The two-view study means that each breast is imaged from two different angles, which increases the likelihood of identifying any abnormalities that may not be visible from a single view. Screening mammograms are crucial for early detection of breast cancer, as they can identify tumors that are too small to be felt during a physical examination.
