Health Insurers Plan Hikes

Aetna Inc., some BlueCross BlueShield plans and other smaller carriers have asked for premium increases of between 1% and 9% to pay for extra benefits required under the law, according to filings with state regulators.

These and other insurers say Congress’s landmark refashioning of U.S. health coverage, which passed in March after a brutal fight, is causing them to pass on more costs to consumers than Democrats predicted.
