CPT® Code 80188

The CPT® Code 80188 refers to a laboratory test specifically designed to measure the levels of primidone in the blood. Primidone, which is commonly known by its brand name Mysoline, is classified as an anticonvulsant medication. It is primarily prescribed for the management of seizures and essential tremor, conditions that involve abnormal electrical activity in the brain. The mechanism of action of primidone involves the reduction of this electrical activity, thereby helping to stabilize neuronal function and prevent seizure episodes. The administration of primidone is typically done orally, and it is crucial for healthcare providers to monitor the blood concentration levels of the drug at regular intervals. This monitoring is particularly important when patients experience breakthrough seizures, as these episodes may indicate that the therapeutic levels of the medication are insufficient. To perform this test, a blood sample is collected through a procedure known as venipuncture, which is separately reportable. The analysis of the blood serum is conducted using a technique called fluorescence polarization immunoassay, which allows for accurate measurement of the drug levels in the bloodstream.
