The Centers for Medicare & Medicaid Services (CMS) released a new report today showing that consumers have received more than $2.4 billion premium rebates since 2011 because the Affordable Care Act requires that health insurance companies spend at least 80 percent of premium dollars on health care. For 2014 alone, over 5.5 million consumers received nearly $470 million in rebates, for an average of $129 per family.
