Massachusetts insurers to boost rates about 10%

Major health insurers in Massachusetts plan to raise premiums by about 10% in 2010, prompting many employers to reduce benefits and shift additional costs to workers. Increases will range from 7%-12%, capping a decade of consecutive double-digit premium increases, according to a survey of the state's top health insurers. Actual rates for 2010 will depend on the size of the employer and the type of coverage, with small businesses and individuals expected to be hit hardest. Overall, premiums in Massachusetts are more than twice as high as they were 10 years ago.
