CPT® Code 82742

Deleted

The CPT® Code 82742 refers to a laboratory test specifically designed to measure the concentration of Flurazepam in the bloodstream. Flurazepam is a medication classified as a benzodiazepine, which is commonly prescribed under the brand name Dalmane. This medication is primarily utilized for the treatment of insomnia, as it effectively lowers brain activity, facilitating the onset of sleep. In addition to its sedative properties, Flurazepam is also beneficial in managing anxiety, relaxing skeletal muscles, and reducing seizure activity. One notable characteristic of Flurazepam is its long half-life, which allows it to remain detectable in the bloodstream for up to four days following ingestion. This extended duration of action makes Flurazepam particularly useful when administered the night before a medical or dental procedure, as it not only promotes sleep but also helps to alleviate anxiety that may be experienced the following day. The testing process for Flurazepam involves obtaining a blood sample through a procedure known as venipuncture, which is reported separately. The analysis of the serum or plasma is conducted using a sophisticated technique called quantitative liquid chromatography-tandem mass spectrometry, ensuring accurate measurement of the drug's levels in the patient's system.
