CPT® Code 87491

The CPT® Code 87491 refers to the detection of the infectious agent Chlamydia trachomatis through nucleic acid techniques, specifically utilizing an amplified probe technique. This method is crucial for identifying infections caused by Chlamydia trachomatis, which is a common sexually transmitted disease (STD). The amplified probe technique enhances the sensitivity of the test, allowing for the detection of Chlamydia nucleic acids, which may be present in low quantities in the specimen. This is particularly important as Chlamydia infections often do not present noticeable symptoms, especially in women, leading to potential long-term complications such as infertility if left untreated. In men, while symptoms such as burning and itching of the urethra may occur, they typically do not experience the same level of reproductive damage. The testing process involves collecting a specimen using a swab from areas such as the cervix, male urethra, or eye, and the methodology can vary depending on the test kit used. The amplified probe technique, such as polymerase chain reaction (PCR), is employed to create multiple copies of the Chlamydia nucleic acids, ensuring accurate detection even when the organism is present in low levels. This procedure is vital for timely diagnosis and treatment, thereby reducing the risk of complications associated with untreated Chlamydia infections.
