CPT® Code 82664

The CPT® Code 82664 refers to an electrophoretic technique that is not specified elsewhere in the coding system. This laboratory test employs electrophoresis, which is a sophisticated analytical method utilized for the separation and characterization of various molecules found in blood and other body fluids. Electrophoresis operates on the principle that charged particles will migrate in an electric field, allowing for the separation of these particles based on their size and electrical charge. As a result, this technique generates a distinct pattern of bands that vary in width and intensity, which can be analyzed to provide valuable diagnostic information. The code 82664 is particularly applicable for conducting a chylomicron screen of body fluids, where qualitative electrophoresis is used to assess the presence and characteristics of chylomicrons. Chylomicrons are small lipoprotein particles that play a crucial role in the transport of dietary fats, consisting of triglycerides, phospholipids, cholesterol, and proteins. This test is essential for understanding lipid metabolism and can aid in diagnosing various metabolic disorders.
