Cardiointegram (CIG) as an Alternative to Stress Test or

20.27 - Cardiointegram (CIG) as an Alternative to Stress Test or Thallium Stress Test (Rev. 1, 10-03-03) CIM 50-47 Not Covered A cardiointegram device consists of a microcomputer which receives output from a standard electrocardiogram (EKG) and transforms it to produce a graphic representation of heart electrophysiologic signals. This procedure is used primarily as a substitute for Exercise Tolerance Testing with Thallium Imaging in patients for whom a resting EKG may be inadequate to identify changes compatible with coronary artery disease. Because this device is still considered investigational pending additional data on its clinical efficacy/sensitivity and value as a diagnostic tool, program payment may not be made for its use at this time.
