In a June 2, 2014 letter addressed to Secretary Sebelius, the American Hospital Association (AHA) expressed concern regarding an increase in OIG’s hospital compliance reviews that use audit findings to extrapolate overpayment amounts.  The AHA requested an immediate end to the audits, arguing that they are redundant to RAC reviews and the overpayments identified are erroneous and inconsistent with Medicare guidance.  AHA’s letter is available here.
