The OIG has issued a report on “Payments for Ambulance Transportation Provided to Beneficiaries in Skilled Nursing Stays Covered Under Medicare Part A in Calendar Year 2006.” The OIG concluded that ambulance suppliers did not always comply with skilled nursing facility (SNF) consolidated billing requirements in calendar year 2006, resulting in an estimated $12.7 million in potential overpayments.  The OIG recommends that CMS recover the overpayments, provide additional guidance for ambulance suppliers and SNFs, and either establish additional claims edits or post-payment reviews to prevent and detect overpayments.  CMS concurred with the recommendations.
