CPT® Code 82525

The CPT® Code 82525 refers to the laboratory test for measuring copper levels in blood, urine, or liver tissue. Copper is a vital trace mineral that plays a crucial role in various enzymatic reactions within the body, contributing to processes such as iron metabolism, the formation of connective tissue, and the functioning of the nervous system. The assessment of copper levels is important for diagnosing and monitoring several medical conditions. Elevated copper levels may indicate the presence of Wilson disease, a genetic disorder that leads to excessive copper accumulation in the body, as well as conditions such as pregnancy, certain illnesses or infections, stress, and the intake of specific medications, including oral contraceptives and nutritional supplements. Conversely, decreased copper levels can occur due to factors such as corticosteroid use, malnutrition, or malabsorption syndromes, which can impair the body's ability to absorb essential nutrients. The testing process involves obtaining a blood sample through a venipuncture, a liver sample via a liver biopsy, or a urine sample collected over a 24-hour period. The analysis of these samples is performed using quantitative inductively coupled plasma-mass spectrometry, a highly sensitive technique that allows for precise measurement of copper concentrations.
