CPT® Code 80177

Levetiracetam is a medication classified as an anticonvulsant, primarily utilized in the management of seizure disorders. The CPT® Code 80177 refers to a specific blood test that quantifies the levels of levetiracetam in a patient's bloodstream. This measurement is crucial for healthcare providers to ensure that the patient is receiving an appropriate dosage of the medication, as both subtherapeutic and supratherapeutic levels can lead to inadequate seizure control or increased risk of adverse effects, respectively. The test is performed by obtaining a blood sample through venipuncture, which is a standard procedure for collecting blood. The analysis of the blood sample is conducted using a quantitative enzyme immunoassay, a laboratory technique that allows for precise measurement of the drug concentration in serum and/or plasma. In addition to its primary use for seizure disorders, levetiracetam may also be prescribed off-label for various conditions, including neuropathic pain, Tourette's syndrome, autism, bipolar disorder, anxiety disorder, and Alzheimer's disease, highlighting the importance of monitoring its levels in diverse therapeutic contexts.
