Thank you for your inquiry specific to CMS145v9- Coronary Artery Disease (CAD): Beta-Blocker Therapy-Prior Myocardial Infarction (MI) or Left Ventricular Systolic Dysfunction (LVEF <40%). After reviewing your test case scenario and conducting additional testing, we have confirmed that the measure logic, as currently written, will erroneously include the patient in both populations, as the logic currently does not consider LVSDFindings that start before the end of the second qualifying encounter. While we will look to implement a solution to this discrepancy, there is currently no solution. We greatly appreciate you bringing this issue to our attention.
