CPT® Code 82542

Column chromatography, includes mass spectrometry, if performed (eg, HPLC, LC, LC/MS, LC/MS-MS, GC, GC/MS-MS, GC/MS, HPLC/MS), non-drug analyte(s) not elsewhere specified, qualitative or quantitative, each specimen

Column chromatography, often combined with mass spectrometry, is a sophisticated analytical technique used to separate and identify chemical components within a sample. This method involves two phases: a stationary phase, where the sample is placed, and a mobile phase, which can be either a gas or liquid that moves through the stationary phase. As the sample is introduced, the various components interact differently with the stationary phase, leading to their separation. Once separated, these components are then measured and analyzed using mass spectrometry, which provides precise information about their molecular structure and weight. This dual approach enhances the sensitivity and specificity of the analysis, making it particularly effective for detecting a wide range of substances, including contaminants in biological fluids such as blood, urine, oral fluids, hair, and sweat. The CPT® Code 82542 encompasses both qualitative and quantitative assessments of non-drug analytes that are not specified elsewhere, ensuring comprehensive testing for each specimen analyzed.
