CPT® Code 56820

The procedure described by CPT® Code 56820 refers to a colposcopy of the vulva, which is a diagnostic examination performed by a physician to closely inspect the vulvar tissue. A colposcope, a specialized instrument resembling binoculars mounted on a stand, is utilized during this procedure. It is equipped with a light source that enhances visibility, allowing the physician to magnify and examine the vulvar tissue in detail. The examination is comprehensive, covering the entire vulva, and is conducted under varying magnifications—typically two or three—to facilitate the identification of any abnormal tissue. To improve the visualization of abnormal cells, acetic acid is applied to the vulvar area. This application helps to highlight areas of concern by causing abnormal cells to appear differently than normal cells. Following this, different-colored filters are employed to observe blood vessels and any unusual patterns that may indicate pathology. Additionally, an iodine solution is applied to stain the glycogen present in the cells; normal cells will take on a dark-brown hue, while areas that do not stain are indicative of potential abnormalities. These non-staining areas, along with any previously identified abnormal blood vessel patterns, are targeted for biopsy if necessary. It is important to note that CPT® Code 56820 is specifically used for colposcopy of the vulva without any biopsies, while CPT® Code 56821 is designated for cases where one or more biopsies are performed during the procedure.
