Faculty

Dr. Maykuth is a statistical expert with particular skill in experimental design, statistical sampling and methodology. She has been President of her firm for over 30 years.

She has been involved in more than 150 civil and criminal trials relating to statistics and consumer attitudes and behaviors. She has been directly responsible for statistical review of over 120 Medicare and Medicaid fair hearing officer and Medicare and Medicaid administrative law judge hearings which involved the application of statistical sampling and projection techniques in audits of a variety of categories of health care providers and suppliers. Her firm is frequently engaged to assist providors conduct Voluntary Repayment estimations and in establishing criteria for measurement in quality based payment systems.

Mr. Ross concentrates his practice on Medicaid, Medicare and private insurance audits & investigations, and health law including fraud and abuse, governmental investigations, criminal defense, administrative hearings, Federal and State False Claims whistleblower cases, Medicaid compliance plans, and Article 78 cases.

In addition to serving the OMIG as General Counsel, he was the Deputy Medicaid Inspector General for Audits and Investigations and oversaw all audits and investigations involving Medicaid providers.
Description
Medicare and individual state Medicaid agencies routinely use samples of providers’ claims universes to extrapolate overpayment determinations. Each year, CMS informs Congress about the large dollar amounts it anticipates it will recoup from healthcare provider’s fraud and abuse activities. Many healthcare providers are impacted by these audits and must defend their documentation and other practices. To successfully challenge these audit determinations of overpayments that need to be repaid to federal health care programs, counsel for providers need to understand proper statistical sampling and extrapolation methods. They need to know how to identify and attack questionable methods and processes to minimize potential repayment obligations.
Government auditors’ statistical practices are presumed valid. it is the provider's burden to overcome that presumption and present sufficient credible 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 disallowances, which typically are relatively small and not worth challenging separately, to be repaid.
Listen as our authoritative panel illustrates how Medicare and Medicaid programs use statistical sampling and extrapolation to seek to recover very large dollar amounts of alleged Medicare and Medicaid overpayments. The panel will discuss how counsel for healthcare providers can obtain the information required to effectively challenge the sampling process and calculated demand amounts.
