N.C. Gen. Stat. § 108C-5.1: Post-payment review and recovery audit contracts.

The Department shall not pay contingent fees pursuant to any contract with an entity conducting Medicaid post-payment reviews or Recovery Audit Contractor (RAC) audits before all appeal rights have been exhausted. Any contingent fee for Medicaid post-payment reviews or RAC audits shall be calculated as a percentage of the amount of the final overpayment, as defined in G.S. 108C-2(5). The State share of the contingent fee paid for Medicaid post-payment reviews or RAC audits shall not exceed the State share of the amount actually recovered by the Department and applied to the final overpayment.
