CPT® Code 80342

The CPT® Code 80342 refers to a laboratory test specifically designed to measure the levels of antipsychotic medications that are not otherwise specified. Antipsychotics are a class of neuroleptic drugs that primarily influence neurotransmitters in the brain, particularly dopamine and serotonin, which play crucial roles in mood regulation and thought processes. These medications are commonly utilized in the treatment of psychotic disorders, such as schizophrenia and bipolar disorder, where patients may experience symptoms like delusions, hallucinations, and disordered thinking. While antipsychotic medications do not provide a cure for these mental health conditions, they are effective in significantly managing and controlling the associated symptoms, thereby improving the quality of life for individuals affected by these disorders. The testing for antipsychotics can be conducted using various analytical methods, including gas chromatography, gas chromatography-mass spectrometry, high-performance liquid chromatography, and liquid chromatography-tandem mass spectrometry. The specific code 80342 is applicable when the laboratory test is focused on detecting 1 to 3 different antipsychotic compounds in a sample, such as urine, serum, or plasma. For tests involving a higher number of compounds, different codes are utilized, with code 80343 designated for 4 to 6 compounds and code 80344 for 7 or more antipsychotic drugs.
