CPT® Code 82271

The CPT® Code 82271 refers to a qualitative test for the presence of occult blood in a fecal (stool) sample, specifically utilizing peroxidase activity, such as that provided by guaiac. This test is primarily employed for screening purposes related to colorectal neoplasms, which are abnormal growths in the colon or rectum that may indicate cancer or precancerous conditions. The term "occult" signifies that the blood is not visible to the naked eye, making this test crucial for early detection of potential gastrointestinal issues. The process involves obtaining a stool sample, which can be collected either in a clinical setting during a rectal examination or at home using a stool collection kit. The kit typically includes multiple cards for the collection of consecutive stool specimens, which are then tested for hidden blood using a chemical reagent. The presence of blood is indicated by a color change on the test card after the reagent is applied. It is important to note that this code is specifically for testing samples from sources other than stool, while different codes exist for other specific testing scenarios, such as the stool samples collected for reasons other than colorectal neoplasm screening.
