CPT® Code 82101

Deleted

The CPT® Code 82101 refers to a laboratory test that quantitatively measures alkaloids in urine. Alkaloids are a class of naturally occurring organic compounds that often have significant pharmacological effects. This test is particularly relevant in the context of substance abuse monitoring and chronic pain management. It is designed to detect the presence of alkaloid end-products resulting from the ingestion of various drugs or medications, including but not limited to codeine, morphine, cocaine, tobacco, and certain herbal substances. The quantitative aspect of this test is crucial as it provides a measurable evaluation of alkaloid levels in the urine, which can inform clinical decisions regarding a patient's treatment plan. The test is indicated in several scenarios: when there is a medically necessary reason to monitor a patient for drug use, when a qualitative test returns negative results for a prescribed medication, after a positive qualitative test for a drug with potential for abuse that was not prescribed, or when a patient tests positive for illegal substances such as methamphetamine or cocaine. The quantitative results serve as a guide for clinical care, helping healthcare providers make informed decisions about ongoing treatment and management of the patient's condition. To perform the test, a urine sample is collected, which can be obtained either through a voided specimen or catheterization. The analysis of the urine sample is conducted using advanced techniques such as liquid chromatography-tandem mass spectrometry, ensuring accurate and reliable results.
