"The whole idea of Medicare Advantage was to drive down the cost of health insurance for the elderly as private insurance companies competing for seniors’ business.
That’s not what happened. By 2010, the average Medicare Advantage per-patient cost was 117 percent of regular fee-for-service. The Affordable Care Act gives those private plans a haircut and tethers reimbursement levels to the quality of care administered, and patient satisfaction."

Hospitals agreed to these cuts because they knew, at the same time, they would likely see an influx of paying patients with the Affordable Care Act’s insurance expansion."
