CPT® Code 57455

The procedure described by CPT® Code 57455 involves a colposcopy of the cervix and the upper adjacent vagina, which is a diagnostic examination performed by a physician to assess the health of these areas. A colposcope, a specialized instrument resembling binoculars mounted on a stand with an integrated light source, is utilized to magnify the tissues of the cervix and upper adjacent vagina. This enhanced visualization is crucial for identifying any abnormal tissue that may require further investigation. During the procedure, the colposcope is positioned at the vaginal opening, and a speculum is inserted into the vagina to gently separate the vaginal walls, providing a clear view of the cervix and upper adjacent vaginal wall. The examination is conducted under varying magnifications, typically two or three, to ensure thorough assessment. To improve the visibility of abnormal cells, acetic acid is applied to the cervix and upper adjacent vagina. This application helps to highlight any areas of concern. Following this, different-colored filters are employed to visualize blood vessels and detect any abnormal patterns in blood vessel formation. Additionally, an iodine solution is applied to stain the cells, where normal cells will exhibit a dark-brown color due to the presence of glycogen. Areas that do not take up the iodine stain, as well as those previously identified with abnormal blood vessel patterns, are targeted for biopsy. If necessary, an endocervical curettage (ECC) may be performed, which involves scraping the cervical canal with a curet to collect tissue samples for further analysis. This comprehensive approach allows for accurate diagnosis and management of cervical and vaginal health issues.
