CPT® Code 85048

An automated white blood cell (WBC/leukocyte) count, represented by CPT® Code 85048, is a laboratory procedure that quantifies the number of leukocytes present in a specific volume of blood. This test is crucial for evaluating variations in leukocyte levels, which can indicate various health conditions. The leukocyte count is particularly significant in monitoring patients with conditions such as HIV and AIDS, where the immune system is compromised, leading to potential decreases in WBCs. Additionally, this count is essential for patients undergoing medical therapies like chemotherapy or radiation therapy, which can also result in a reduction of white blood cells. Furthermore, an elevated leukocyte count may signal the presence of bacterial infections, inflammatory responses, leukemia, or trauma. The procedure utilizes an automated blood cell counting instrument, ensuring accuracy and efficiency in obtaining the leukocyte count, which is vital for diagnosing and managing various medical conditions.
