Dimethadione

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 82654 refers to a laboratory test specifically designed to measure the concentration of dimethadione in the blood. Dimethadione is a significant metabolite of trimethadione, which is an anti-convulsant medication. This test is particularly relevant for patients who are undergoing treatment for epilepsy, especially those whose condition is resistant to other forms of medication or therapeutic interventions. The measurement of dimethadione levels is crucial for clinical monitoring, as it helps healthcare providers assess the effectiveness of the treatment and make necessary adjustments to the patient's medication regimen. To perform this test, a blood sample is collected through a procedure known as venipuncture, which is a separate and reportable action. The results of this test can provide valuable insights into the patient's response to treatment and guide further clinical decisions.
