CMS is hosting two special open door forums on the Recovery Audit Contractor (RAC) program, through which the RACs will review all Medicare Part A and B paid claims to identify Medicare overpayments and underpayments. The RACs will be paid a contingency fee based on overpayments and underpayments they find. The first forum, scheduled for November 12, 2008, is designed for Part A providers, while the second forum on November 13 is targeted at Part B providers.
