When conducting a Discovery Sample, how is the error rate determined?
In a Discovery Sample, each sampling unit is evaluated to determine the dollar difference between the amount that was reimbursed and the amount that should have been reimbursed. Once all sampling units have been reviewed, the results of each sampling unit are added together (underpayments may be netted or offset from overpayments). The resulting calculation is the net overpayment. The reviewer divides the net overpayment by the total dollar amount of the sample. The resulting calculation is the error rate.
