Ninety-four of the one hundred sampled high-dollar Medicare Part B payments ($10,000 or more) that National Government Services made to providers during calendar years (CY) 20032005 were appropriate.  However, National Government Services overpaid providers $39,196 for the remaining six payments.  Providers refunded two overpayments totaling $30,075 and partially refunded one overpayment ($7,707 of $7,837) prior to the end of our fieldwork.  Four overpayments totaling $1,414 remained outstanding.  National Government Services, the Medicare Part B carrier for about 48,000 providers in 16 southeastern New York counties, made 942 high-dollar payments in CYs 20032005.

We recommended that National Government Services (1) recover the $1,414 in overpayments, (2) review the remaining 842 high-dollar claims processed during CYs 20032005 and work with the providers that claimed these services to recover any overpayments, (3) consider identifying and recovering any additional overpayments made for high-dollar Part B claims paid after CY 2005, and (4) use the results of this audit in its provider education activities.  National Government Services agreed with our recommendations.
