CPT® Code 99170

The CPT® Code 99170 refers to a specialized procedure known as an anogenital examination, which is conducted in children when there is a suspicion of trauma, particularly in cases of potential sexual abuse. This examination is performed using a colposcope, a medical instrument that resembles binoculars mounted on a stand, equipped with a light source. The primary purpose of the colposcope is to magnify the tissues of the anogenital area, which includes the vagina, anus, and perineum, thereby enhancing the clinician's ability to visualize any signs of trauma or injury. During the examination, the colposcope is positioned at the vaginal or anal opening, allowing for a thorough inspection of the area. A speculum is then inserted into the vagina or anus to gently separate the walls, enabling a comprehensive examination of the entire circumference of the vaginal or anal wall. The clinician rotates the speculum to ensure that all areas are adequately inspected. The examination is conducted under varying magnifications, typically two or three, to provide a detailed view of the tissues. Additionally, a videocolposcope may be utilized to capture images of the vaginal and anal tissues, which serves as documentation of any observed trauma. This procedure is critical in pediatric cases where there is a concern for sexual abuse, as it allows for a meticulous evaluation of the anogenital region and the potential recording of evidence through imaging.
