CPT® Code 82747

The CPT® Code 82747 refers to a laboratory test that measures the levels of folic acid, also known as folate, specifically in red blood cells (RBCs). Folic acid is a vital nutrient, classified as Vitamin B9, which plays a crucial role in various bodily functions, including the growth, division, and repair of cells. This nutrient is particularly important during periods of rapid growth, such as fetal development during pregnancy and early infancy. Adequate levels of folic acid are essential for the production of healthy red blood cells, which helps prevent anemia across all age groups. The test associated with this code is utilized not only for diagnosing anemia but also for identifying certain neuropathies and monitoring the effectiveness of treatments for these conditions. To perform this test, a blood sample is collected, typically through a procedure known as venipuncture, which is reported separately. It is important to note that when measuring serum folic acid levels, the CPT® Code 82746 should be used instead. The measurement of folic acid in RBCs reflects the levels present at the time the cells were produced, which can be up to two months prior to the test. Both the RBC and serum folic acid tests are generally conducted using a quantitative chemiluminescent immunoassay method, ensuring accurate and reliable results.
