CPT® Code 83695

The CPT® Code 83695 refers to the laboratory test for measuring lipoprotein (a), commonly abbreviated as Lp (a). This test is crucial for assessing the levels of lipoprotein (a) in the blood, which is a type of lipoprotein that consists of low-density lipoprotein (LDL) cholesterol bound to a specific protein known as apolipoprotein (a). The measurement of Lp (a) is significant because its levels are primarily determined by genetic factors and tend to remain stable throughout an individual's life. This test serves as an important risk marker for cardiovascular disease, as elevated levels of lipoprotein (a) can indicate an increased risk for heart-related conditions. Factors that may lead to elevated Lp (a) levels include hormonal changes such as depleted estrogen, genetic conditions like familial hypercholesterolemia, and other health issues such as hypothyroidism, diabetes, and kidney disease. To perform this test, a blood sample is collected, typically through a procedure known as venipuncture, which is separately reportable. The analysis of the serum or plasma is conducted using a method called quantitative immunoturbidimetry, which allows for accurate measurement of lipoprotein (a) concentrations in the blood.
