This CLE webinar will provide insight to counsel for Medicare and Medicaid providers on how to effectively evaluate and potentially challenge overpayment sampling and extrapolations in provider audits.

Description

Medicare and individual state Medicaid agencies are using statistical sampling and extrapolation to determine overpayments in their audits and investigations. Centers for Medicare & Medicaid Services (“CMS”) revised its Medicare Program Integrity Manual (MPIM) provisions on sampling and extrapolation which became effective in 2019. The MPIM provides additional information regarding several aspects of the sampling and extrapolation process that providers should consider when challenging extrapolated reviews by payors.

A sample of claims is audited and the results of that audit are extrapolated to the claims universe, resulting in substantial repayment demands on providers. When facing an alleged overpayment, Medicare and Medicaid providers generally have the burden of demonstrating that the reimbursement they received was proper. If the Medicare or state Medicaid agency uses statistical sampling and extrapolation to establish the overpayment, it is the provider's burden generally to present sufficient evidence to refute the sampling and the extrapolation process. If the provider is successful, the extrapolated repayment amount will be removed from the case, leaving only the sample disallowance findings and corresponding repayment to be challenged. This is typically much less of a financial burden to the provider than the extrapolated result.

To challenge these state determinations of overpayment, Medicaid providers can look to Medicare rulings and cases for persuasive, but not binding, guidance. The rules of statistics need to be observed for an extrapolated result to be valid. It is critical for Medicare and Medicaid providers and their counsel to understand proper statistical sampling and extrapolation methods, and to know how to challenge questionable processes to minimize potential repayment obligations.

Listen as our authoritative panel examines how Medicare and Medicaid programs are using statistical sampling and extrapolation to recover alleged Medicare and Medicaid overpayments. The panel will discuss how counsel for health care providers can effectively challenge the sampling and extrapolation methodology and the alleged resulting overpayment.
