CPT® Code 85007

The CPT® Code 85007 refers to a specific laboratory procedure known as a blood count that includes a blood smear and a microscopic examination with a manual differential white blood cell (WBC) count. This procedure is essential for evaluating the composition of blood, particularly in identifying abnormalities in blood cells. A blood smear involves spreading a thin layer of blood on a microscope slide, which is then stained to enhance the visibility of the cells. The microscopic examination allows for the assessment of the morphology of blood cells, which can reveal critical information about a patient's health status. Typically, a blood smear is performed following an automated blood test that suggests the presence of abnormal or immature blood cells. It may also be indicated when a physician suspects a hematological condition, such as anemia, which affects blood cell production. The process begins with obtaining a blood sample through a venipuncture, which is a separate reportable procedure. Once the blood sample is collected, a technician prepares the smear and examines it under a microscope, focusing on identifying immature or abnormal cells. In the context of CPT® Code 85007, the procedure includes a manual differential WBC count, where the technician meticulously examines and counts the five distinct types of white blood cells: neutrophils, eosinophils, basophils, monocytes, and lymphocytes. Each type of WBC has unique characteristics and functions, and their relative proportions can provide valuable insights into a patient's immune response and overall health. For instance, neutrophils are the most abundant WBCs in healthy adults, while eosinophils and basophils are typically present in smaller percentages and can indicate specific conditions when elevated. Monocytes and lymphocytes play crucial roles in the immune system, with lymphocytes being responsible for antibody production. Overall, this procedure is a vital diagnostic tool in clinical practice, aiding in the detection and management of various medical conditions.
