Last week, Sens. Baucus (D-MT) and Grassley (R-IA) and Reps. Stark (D-CA), Levin (D-MI) and Waxman (D-CA) released a GAO report describing how physician self-referrals affect overall health spending. According to the report, in 2010, Medicare spent about $109 million that it could have avoided without self-referrals. In a statement, Baucus explained that "[s]elf-referrals offer an incentive for providers to order more tests than they would otherwise. It's clear they are driving up costs. Providers' bottom lines shouldn't be getting in the way of their patients' care and best interests."
