CPT® Code 80175

The CPT® Code 80175 refers to a laboratory test specifically designed to measure the levels of lamotrigine in the blood. Lamotrigine, marketed under the brand name Lamictal, is classified as an anticonvulsant medication belonging to the phenyltriazine class. It is primarily utilized in the management of seizure disorders, including epilepsy, and is also indicated for the treatment of bipolar disorder. In addition to its approved uses, lamotrigine may be prescribed off-label for various conditions such as peripheral neuropathy, migraine headaches, and depression that does not involve manic episodes. 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 quantitative enzyme immunoassay, which allows for precise measurement of the drug's concentration in serum and/or plasma, thereby aiding healthcare providers in monitoring therapeutic levels and adjusting dosages as necessary.
