CPT® Code 83825

The CPT® Code 83825 refers to a quantitative test for mercury levels in various biological samples, including blood, urine, hair, fingernails, and other body tissues. Mercury is classified as a heavy metal, and exposure to high levels can be toxic to the human body. Individuals may encounter mercury through several routes, such as consuming certain types of fish that contain mercury, exposure to dental amalgams used in fillings, the presence of thimerosal as a preservative in some vaccines, or through occupational exposure in certain work environments. The testing process involves obtaining a blood sample, which is performed through a separately reportable venipuncture. The analysis of whole blood is conducted using quantitative atomic absorption or quantitative inductively coupled plasma-mass spectrometry techniques. Additionally, a random voided or 24-hour urine specimen can be collected and tested using quantitative inductively coupled plasma-mass spectrometry. For scalp hair, fingernail clippings, and other body tissue samples, the testing is performed using inductively coupled plasma/mass spectrometry methods. This comprehensive approach allows for accurate measurement of mercury levels, which is essential for assessing potential toxicity and guiding further medical evaluation or intervention.
