I have long argued that the impact of the Affordable Care Act is not nearly as big of a deal as opponents would have you believe. At the end of the day, the law is – in the main – little more than a successful effort to put an end to some of the more egregious health insurer abuses while creating an environment that should bring more Americans into programs that will give them at least some of the health care coverage they need.

There is, however, one notable exception – and it's one that should have a long lasting and powerful impact on the future of health care in our country.

That would be the provision of the law, called the medical loss ratio, that requires health insurance companies to spend 80% of the consumers' premium dollars they collect—85% for large group insurers—on actual medical care rather than overhead, marketing expenses and profit. Failure on the part of insurers to meet this requirement will result in the insurers having to send their customers a rebate check representing the amount in which they underspend on actual medical care.
