This aims to prevent improper payments before they are made, rather than just recouping them after the fact. Key provisions of the legislation include the authorization for recovery audit contractors to perform prepayment reviews of Medicare claims. It establishes a payment structure for these contractors based on their success in preventing improper payments.
