CPT® Code 85018

The CPT® Code 85018 refers to a specific blood test that measures the level of hemoglobin (Hgb) in a patient's blood. Hemoglobin is a vital protein found in red blood cells that is responsible for transporting oxygen throughout the body. This test is crucial for assessing various medical conditions, particularly those related to blood health. The measurement of hemoglobin is primarily utilized to evaluate the severity of anemia, a condition characterized by a deficiency of red blood cells or hemoglobin, which can lead to fatigue and weakness. Conversely, it is also used to assess polycythemia, a condition where there is an excess of red blood cells, which can increase the risk of blood clots and other complications. The hemoglobin test can be performed in different settings, including a physician's office or a laboratory. The process begins with the collection of a blood sample, which can be obtained through various methods such as venipuncture, or by using a finger, heel, or ear stick. Once the sample is collected, it may either be sent to a laboratory for analysis or analyzed on-site using a rapid testing system. These rapid testing systems typically consist of a portable photometer and pipettes containing a reagent. The pipette is used to draw the blood sample from the capillary stick, and the blood is mixed with the reagent within the pipette. The photometer then reads the resulting mixture, providing an immediate display of the hemoglobin level. This test is essential for monitoring a patient's response to treatment for anemia or polycythemia and determining the necessity for blood transfusions based on the hemoglobin levels measured.
