CPT® Code 82143

An amniotic fluid scan, identified by CPT® Code 82143, is a diagnostic procedure that utilizes spectrophotometric methodology to assess bilirubin levels within the amniotic fluid. This scan is particularly significant in the context of evaluating potential maternal-fetal blood incompatibility or hemolytic disease of the fetus, conditions that can arise when there is an incompatibility between the blood types of the mother and the fetus. To perform this test, a separate procedure known as amniocentesis is conducted to obtain a sample of the amniotic fluid. During the scan, a spectrophotometer is employed, which is an instrument that measures the intensity of light at a specific wavelength as it passes through the amniotic fluid. This measurement provides a quantitative assessment of the bilirubin concentration present in the fluid, which is crucial for determining the health status of the fetus and guiding further clinical management. The results of the amniotic fluid scan can help healthcare providers make informed decisions regarding the need for additional interventions or monitoring during the pregnancy.
