CPT® Code 80171

The CPT® Code 80171 refers to a laboratory test that measures the levels of gabapentin in whole blood, serum, or plasma. Gabapentin, which is marketed under brand names such as Gabarone and Neurontin, is a medication that acts as an analog of gamma-aminobutyric acid (GABA), a neurotransmitter that plays a crucial role in regulating neuronal excitability throughout the nervous system. This medication is primarily utilized in the management of seizure disorders and chronic neuropathic pain, providing relief to patients suffering from these conditions. Additionally, gabapentin may be prescribed off-label for various other conditions, including migraine headaches and bipolar disorder, highlighting its versatility in treating different neurological and psychiatric disorders. The testing process involves obtaining a blood sample through a procedure known as venipuncture, which is separately reportable. The analysis of the blood sample is conducted using a sophisticated technique known as quantitative liquid chromatography-tandem mass spectrometry, which allows for precise measurement of gabapentin levels in the sample. This test is essential for monitoring therapeutic levels of the drug, ensuring efficacy, and minimizing potential toxicity in patients undergoing treatment.
