Health insurers in Massachusetts will boost rates more than 6 percent for small businesses and individuals in 2016, a troubling sign that costs are once again accelerating.
The increase, approved by the state Division of Insurance last week, is more than double the rise in premiums at the beginning of this year and triple the rise in 2014.
The new rates will affect about 300,000 people who buy health insurance on their own or work for small businesses with 50 or fewer employees and will renew plans in January.
