Medicare Advantage overpayments

Newly released Medicare Advantage plan audits for a sample of 2007 patients show government officials cited 35 of 37 plans they reviewed for overcharging. This chart shows the original amount each plan was paid in 2007, the adjusted amount auditors determined should have been paid, and the alleged net overpayment. Many plans have appealed the findings. Two health plans, Group Health Cooperative in Washington State and a Kaiser Foundation Health Plan in California had no net overpayment.
