CPT® Code 85049

An automated platelet count, designated by CPT® Code 85049, is a laboratory procedure that quantifies the number of platelets in a blood sample. Platelets, or thrombocytes, are small cell fragments in the blood that play a crucial role in the clotting process, helping to prevent excessive bleeding when injuries occur. This procedure is essential for diagnosing various medical conditions, particularly bleeding disorders such as von Willebrand disease, which affects the blood's ability to clot properly. Additionally, it is utilized in the evaluation of bone marrow diseases, including leukemia and other hematological malignancies. The automated platelet count is particularly important for monitoring patients who have undergone bone marrow transplants, are receiving chemotherapy, or suffer from chronic kidney disease or autoimmune disorders, as these conditions can significantly impact platelet production and function. The counting of platelets is performed using sophisticated automated devices that provide accurate and efficient results, ensuring timely diagnosis and management of the aforementioned conditions.
