CPT® Code 85008

The CPT® Code 85008 refers to a specific laboratory procedure known as a blood count that includes a blood smear and a microscopic examination without a manual differential white blood cell (WBC) count. This procedure is essential for evaluating the characteristics of blood cells, particularly when there are indications of abnormalities. A blood smear involves spreading a thin layer of blood on a microscope slide, which is then stained and examined under a microscope by a trained technician. This examination allows for the identification of immature or abnormal blood cells that may not be detected through automated blood tests alone. The procedure is typically indicated when an automated test suggests the presence of irregularities in blood cell production or morphology, such as in cases of anemia or other hematological conditions. It is important to note that while this code does not include a manual differential WBC count, which is a more detailed analysis of the different types of white blood cells, it still provides valuable information regarding the overall health of the blood. A blood sample for this procedure is obtained through a venipuncture, which is a separate reportable service. The technician's examination focuses on identifying any significant deviations in the blood cell population, which can aid in diagnosing various medical conditions.
