Since 2004, the government has paid Medicare Advantage plans using a complex tool called a risk score. The idea is to pay higher rates for sicker patients and less for those in good health. But over the past decade, officials have struggled to control sharp increases in risk scores that have cost taxpayers billions of dollars. The industry says higher scores result from sicker patients and more thorough documentation of their health. Critics dispute that and want the government to make public more billing records that would help determine if health plans are being paid too much. This graphic plots changes in risk scores at more than 5,700 health plans in 3,000 counties nationwide between 2007 and 2011.
