CPT® Code 80306

Drug test(s), presumptive, any number of drug classes, any number of devices or procedures; read by instrument assisted direct optical observation (eg, utilizing immunoassay [eg, dipsticks, cups, cards, or cartridges]), includes sample validation when performed, per date of service

The CPT® Code 80306 refers to a laboratory procedure designed for the presumptive testing of drugs in a patient's system. This test is utilized to detect the presence or absence of various drug classes during a specific medical encounter. Presumptive drug testing serves as an initial screening method, which is typically followed by more definitive testing to identify specific drugs and their quantitative levels. It is important to note that presumptive testing does not provide qualitative identification of individual drugs or the exact amounts present in the sample. The procedure involves obtaining a sample, which is usually blood or urine, through a separately reported procedure. The methodologies employed in this testing include immunoassays, chromatography, and mass spectrometry, which are essential for accurate detection and analysis. The code 80306 specifically indicates that the presumptive drug testing is performed using FDA-specified equipment that supports moderate complexity testing methodologies, with the results being read through instrument-assisted direct optical observation. This includes the use of various devices such as dipsticks, cups, cards, or cartridges, and may also involve sample validation processes when applicable.
