In the first and second levels of Medicare appeals (redetermination and reconsideration) extrapolated overpayments are reviewed by MAC (Medicare Administrative Contractors) and by QICs (Qualified Independent Contractors).

The OIG audit was to make sure that the MACs and the QICs reviewed the appealed extrapolated overpayments consistently and in compliance with CMS requirements.

What OIG found was that CMS did not always provide sufficient guidance and oversight to ensure that these reviews were performed in a consistent manner.  The most significant inconsistency identified was the use of a type of simulation testing that was performed only by a subset of contractors.  The test was associated with at least $42 million in extrapolated overpayments that were overturned in fiscal years 2017 and 2018.Continue reading
