Because of the Affordable Care Act, insurance companies now must reveal how much of premium dollars they actually spend on health care and how much they spend on administration, such as salaries and marketing. This information was not shared with consumers in the past. Not only is this information made available to consumers for the first time, If an insurance company spends less than 80% of premiums on medical care and quality (or less than 85% in the large group market, which is generally insurance provided through large employers), it must rebate the portion of premium dollars that exceeded this limit.[1] This 80/20 rule is commonly known as the Medical Loss Ratio (MLR) rule.
