Ineligible Medicare Payments to Skilled Nursing Facilities Under the Administrative Responsibility of Mutual of Omaha

The objective of this audit was to determine the extent of ineligible Medicare Skilled Nursing Facility (SNF) payments contained in our database of payments made under the administrative responsibility of Mutual of Omaha (Mutual). Our review of the database estimated that $41.5 million of ineligible SNF payments were made under the administrative responsibility of Mutual during calendar years 1997 through 2001. The overpayments occurred because of the absence of an automated cross-check, within the Centers for Medicare and Medicaid Services Common Working File and Mutual's claims processing system, verifying that a three consecutive day inpatient hospital stay occurred prior to SNF admission.
