Audit (A-05-09-00076)

Review of National Government Services, Inc., Medicare Payments to Providers Terminated Between January 1, 2003, and January 31, 2007

Executive Summary

Our review found that National Government Services, Inc. (NGS), a Medicare contractor, had not recovered a total of $2 million in overpayments to 11 providers for Medicare services furnished on or after the effective termination dates of the providersí agreements. Payments for services provided on or after the termination date of a providerís agreement with Medicare are generally not allowable. NGS had not recovered the overpayments because it did not follow its procedures to retroactively identify payments for posttermination services. NGS confirmed that the overpayments were subject to recovery.

We recommended that NGS recover $2 million in overpayments to the 11 terminated providers and follow its procedures to retroactively identify and recover overpayments for services furnished on or after the providersí effective termination dates. NGS agreed with our recommendations.
