This CLE webinar will prepare counsel for healthcare providers to understand the demands of Medicare and Medicaid compliance audits and overpayment investigations. The panel will review sampling process and outline approaches for providers and their counsel to challenge overpayment extrapolations. They will explore critical steps to address requirements for self-report and to review extrapolation audits.

Description

Medicare contractors, such as Zone Program Integrity Contractors (ZPICs) and Uniform Program Integrity Contractors (UPICs), and the Office of Inspector General (OIG), and Medicaid agencies frequently use statistical sampling and extrapolation to determine overpayments in their audits and investigations. A sample of claims is audited, and the results are extrapolated to the claims universe, resulting in substantial repayment demands on providers.

When the government auditor uses statistical sampling to establish the overpayment amounts, the burden is on the provider to present sufficient evidence to refute the results of the sampling and extrapolation process. If the provider succeeds, the extrapolated repayment amount will be removed from the case, leaving only the sample error and corresponding repayment to be challenged. This is typically much less of a financial burden.

To challenge these overpayment determinations, Medicare and Medicaid providers must understand the legal and statistical standards required for an extrapolated result to be valid. It is critical for healthcare 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 auditors are using statistical sampling to recover overpayments. The panel will also guide counsel for healthcare providers on how to challenge the sampling results and the alleged overpayment, leveraging lessons from prior matters.
