Official Description

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.

1. Indications

The laboratory test for dimethadione is indicated for patients who are being treated for epilepsy, particularly those who have not responded adequately to other anti-convulsant medications or treatments. Monitoring the levels of dimethadione is essential for ensuring effective management of the patient's condition and optimizing therapeutic outcomes.

  • Epilepsy Treatment This test is performed for patients with epilepsy who are resistant to other medications.

2. Procedure

The procedure for measuring dimethadione levels involves several key steps that ensure accurate results. First, a healthcare professional will prepare the patient for venipuncture, which is the process of obtaining a blood sample. This involves selecting an appropriate site, typically in the arm, and cleaning the area to prevent infection. Once the site is prepared, a needle is inserted into the vein to draw blood. The collected blood sample is then placed in a suitable container for laboratory analysis. In the laboratory, the sample undergoes testing to quantify the amount of dimethadione present. This quantitative analysis is crucial for clinical monitoring and helps healthcare providers make informed decisions regarding the patient's treatment plan.

  • Step 1: Patient Preparation The healthcare professional prepares the patient for venipuncture by selecting a site and cleaning the area.
  • Step 2: Blood Collection A needle is inserted into the vein to draw a blood sample, which is then placed in a container for analysis.
  • Step 3: Laboratory Analysis The blood sample is tested in the laboratory to quantify the level of dimethadione present.

3. Post-Procedure

After the blood sample has been collected, there are typically no specific post-procedure care requirements for the patient. However, it is important for the healthcare provider to monitor the patient for any immediate adverse reactions to the venipuncture, such as bleeding or discomfort at the site. The results of the dimethadione level test will be communicated to the healthcare provider, who will use this information to assess the patient's response to treatment and make any necessary adjustments to their medication regimen. Regular monitoring may be recommended to ensure optimal therapeutic levels are maintained.
