This July 1, 2017, 1127 hospitals will be included in the Centers for Medicare and Medicaid Services (CMS's) Cardiac Bundle. Of those, 475 will also participate in the Cardiac Rehabilitation Program. Like other mandated retrospective bundled payment programs, these new models are aimed at controlling costs while ensuring quality for what are often expensive and complex procedures. In the case of the Cardiac Bundle, Acute Myocardial Infarctions (heart attacks) and Coronary Artery Bypass Grafts (CABG or bypass surgery) are at aim. Cardiac Rehabilitation has been added to a selection of participating hospitals to test the effectiveness of rehab programs in driving down risk and cost for AMI and CABG patients. Taken together, the bundle is part of a broader program driven by CMS to prevent cardiovascular disease, which causes one in three deaths within the U.S. and costs more than $300 billion each year.
