CPT® Code 83992

The CPT® Code 83992 refers to a laboratory test specifically designed to measure the levels of phencyclidine (PCP) in biological specimens such as blood, urine, or meconium stool. Phencyclidine, commonly known as PCP, is classified as a neurotoxic dissociative anesthetic drug. It is frequently misused by individuals seeking its hallucinogenic effects, which can lead to significant health risks and complications. The testing process involves obtaining a blood sample through a procedure known as venipuncture, which is separately reportable. Alternatively, a urine specimen can be collected via random void, or meconium stool can be gathered from the diaper of a newborn infant. The analysis of these specimens is conducted using a sophisticated technique called quantitative gas chromatography-mass spectrometry, which allows for precise measurement of PCP levels. This test is crucial for assessing exposure to PCP, particularly in cases of suspected drug abuse or in newborns who may have been exposed in utero.
