Aetna CEO: Why insurance will be costing more

 The fact that many current health-care plans do not offer all the benefits required under Obamacare means that many premiums are likely to jump dramatically, Aetna CEO Mark Bertolini told CNBC.

Bertolini, appearing on Tuesday's "Closing Bell," said that most Americans with current plans are below the 60 percent essential Affordable Care Act benefit requirement, and individual plan participants will have to pay a minimum of a 20 percent increase to upgrade, he said.
