CPT® Code 80183

The CPT® Code 80183 refers to a laboratory test specifically designed to measure the levels of oxcarbazepine in the blood. Oxcarbazepine, marketed under the brand name Trileptal, is classified as an anticonvulsant medication, primarily utilized in the management of seizure disorders. In addition to its primary use, oxcarbazepine may also be prescribed off-label for various conditions, including anxiety, mood disorders, and benign motor tics. The testing process involves obtaining a blood sample through a procedure known as venipuncture, which is separately reportable. Once the blood sample is collected, serum or plasma is subjected to analysis for the oxcarbazepine metabolite using a sophisticated technique known as quantitative liquid chromatography-tandem mass spectrometry. This method allows for precise measurement of the drug levels in the bloodstream, which is essential for monitoring therapeutic effectiveness and ensuring patient safety.
