3. Private insurance exchanges

The number of private health insurance exchanges will likely rise this year as more companies consider private exchanges as a way for their employees to buy health insurance using a defined contribution.

For example, IBM and Time Warner have both decided to move some retirees to private exchanges where they can shop for individual coverage using a health retirement account.

"Our expectation is that private exchanges will continue to grow in popularity in 2014, as they give employees an opportunity to customize coverage and provide a predictable amount of spend for the employer," DeVore wrote.
