Since 2013, new health plans in 24 states were launched under the Consumer Operated and Oriented Plan program of the Affordable Care Act. Some were quite successful in enrolling members (1 million as of earlier this year) and offering lower premiums. But co-ops in seven states already have failed or will be closed by the end of this year due to solvency and funding problems. What has already happened, and what is ahead for the remaining co-ops? An expert panel will analyze case histories of failed co-ops, the public policies that shaped them, and implications for health care consumers and taxpayers.
