Ch. 16, § 5. Random Sample and Extrapolation

(a) The Department shall notify the provider via certified mail of its intent to use extrapolation. The notice shall include: (i) The nature of the claims; (ii) The number of claims; and (iii) The method to be used in extrapolating from the sample. (b) The amount of overpayments determined pursuant to extrapolation shall be refutably presumed to be correct. The provider may rebut the presumption by providing, at the provider's expense, an audit using GAAS or SAS, or by demonstrating that the method used by the Department failed to comply with the requirements of this Section.
