CPT® Code 82270

Blood, occult, by peroxidase activity (eg, guaiac), qualitative; feces, consecutive collected specimens with single determination, for colorectal neoplasm screening (ie, patient was provided 3 cards or single triple card for consecutive collection)

The CPT® Code 82270 refers to a qualitative test for the presence of occult blood in feces, specifically utilizing peroxidase activity, such as that provided by guaiac. This test is primarily conducted for colorectal neoplasm screening, which is a critical preventive measure in identifying potential colorectal cancers at an early stage. The procedure involves the collection of stool samples, which may be obtained either in a clinical setting during a rectal examination or at home using a designated stool collection kit. The kit typically includes three separate cards or a single triple card, allowing for the collection of three consecutive stool specimens as per the provided instructions. The significance of this test lies in its ability to detect hidden blood in the stool, which is not visible to the naked eye but can indicate underlying health issues, including colorectal neoplasms. The testing process involves applying a chemical reagent to the stool specimens, where a color change indicates the presence of blood. It is important to note that this code is specifically for the screening of colorectal neoplasms, and other codes, such as 82271 and 82272, are designated for different types of samples or reasons for testing.
