CPT® Code 87172

The CPT® Code 87172 refers to a diagnostic procedure known as a pinworm exam, specifically utilizing a method called the cellophane tape preparation. This examination is designed to detect the presence of pinworms, which are small parasitic worms that can infect the intestines, particularly in children. The procedure involves placing a piece of clear tape over the anal area, which is then removed to collect any pinworm eggs or adult worms that may be present. The tape is subsequently examined under a microscope to identify these parasites. This method is effective because pinworms typically lay their eggs around the anus, especially at night, making the tape collection a practical approach for diagnosis. The pinworm exam is a straightforward, non-invasive procedure that plays a crucial role in diagnosing enterobiasis, the infection caused by pinworms, and is particularly important in pediatric populations where such infections are more common.
