The number of requests by health insurers for double-digit rate increases fell about 41 percentage points since the end of 2009, according to a U.S. report that cited the success of the health-care overhaul. The data today by the U.S. Department of Health and Human Services showed one-third of requests last year asked states to approve premium increases of more than 10 percent. In 2010, three-quarters of petitions sought double-digit jumps, according to the report, which compared 15 states in 2012 with 11 in 2010.
