CPT® Code 80363

The CPT® Code 80363 refers to a laboratory test specifically designed to measure the presence of opioids and opiate analogs in various biological samples, including meconium stool, urine, serum, or plasma. Opioids and opiate analogs encompass a broad category of substances that include naturally occurring opiates such as codeine, morphine, and thebaine, as well as semi-synthetic opioids like hydromorphone, hydrocodone, oxycodone, oxymorphone, buprenorphine, meperidine, methadone, propoxyphene, tapentadol, and tramadol. These substances share a similar chemical structure and pharmacological effects, primarily acting as narcotic analgesics and central nervous system depressants. Clinically, they are prescribed to manage moderate to severe acute or chronic pain. However, due to their effects on the brain's pleasure centers, they can also induce a euphoric state, which may lead to their misuse and abuse by individuals seeking recreational highs. The testing process involves obtaining a blood sample through venipuncture, a urine sample via random void or catheterization, and collecting meconium stool from a diaper. The analysis of serum, plasma, urine, and stool samples is conducted using quantitative liquid chromatography-tandem mass spectrometry, a sophisticated technique that allows for precise measurement of these substances. It is important to note that CPT® Code 80362 is applicable when testing for 1 or 2 opioids/opiate analogs, while Code 80364 is designated for evaluations involving 5 or more opioids/opiate analogs.
