Health insurers are proposing to raise Obamacare rates more than in the past — some by more than 70 percent — now that they are finally equipped with all the information they need to price those plans.

Plans wanting to raise rates by at least 10 percent next year posted the proposed increase online Monday, as required by the 2010 healthcare law. Insurers are allowed to raise rates each year, but they must publish significant increases ahead of time.
