On September 16, 2009, CMS published a final rule that implements a provision of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 that prohibits recouping Medicare overpayments from a provider or supplier that seeks a reconsideration from a Qualified Independent Contractor (QIC) and changes how interest is to be paid to a provider or supplier whose overpayment is reversed at subsequent administrative or judicial levels of appeal. The final rule describes the overpayments to which the limitation applies, how the limitation works in concert with the appeals process, and the change in CMS’s obligation to pay interest to a provider or supplier whose appeal is successful at levels above the QIC. The rule is effective November 16, 2009.
