Higher prices from hospitals, doctors and other providers are the biggest driver of rising health costs, according to a recent study analyzing billions of private insurance claims.
The report from the Health Care Cost Institute is the biggest study to date of privately insured patients. The study examined 3 billion health care claims from 33 million people insured by Aetna, Humana and UnitedHealthcare during 2009 and 2010.
