CPT® Code 80326

The CPT® Code 80326 refers to a laboratory test specifically designed to measure the presence of five or more amphetamines in various biological samples, including serum, urine, saliva, hair, and stool. Amphetamines are a class of central nervous system stimulants that are primarily utilized in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. This category of drugs encompasses not only traditional amphetamines but also designer drugs such as methylenedioxyamphetamine (MDA), methylenedioxymethamphetamine (MDMA, commonly known as Ecstasy), and methylenedioxyethylamphetamine (MDEA, referred to as Eve). These designer drugs possess both stimulant and hallucinogenic properties, which can lead to significant abuse and addiction potential. The testing for amphetamines is crucial, as it helps in monitoring drug use and ensuring patient safety. The detection windows for amphetamines vary by sample type: they can be identified in blood or serum for up to 12 hours post-ingestion, in urine for 2 to 5 days, in saliva for 1 to 5 days, and in hair for as long as 90 days. The methodologies employed for testing include high-performance liquid chromatography coupled with tandem mass spectrometry for serum, urine, and stool samples, while hair samples are analyzed using gas chromatography/mass spectrometry. Saliva testing is conducted through a rapid immunochromatographic assay. This code is part of a series where code 80324 is designated for testing 1 or 2 amphetamines, and code 80325 is for 3 or 4 amphetamines, making 80326 the appropriate choice for testing five or more amphetamines.
