Our audit found that 1,619 of the 1,913 selected line items for which Noridian Administrative Services, LLC (Noridian), made Medicare payments to providers for outpatient services for the period January 1, 2006, through June 30, 2009, were incorrect. The line items included overpayments totaling approximately $5.8 million, which the providers had not refunded by the beginning of our audit. Providers refunded overpayments on 108 line items totaling approximately $2.2 million before our fieldwork. The remaining 186 line items were correct.
Medicare uses an outpatient prospective payment system to pay certain outpatient providers. In this method of reimbursement, the Medicare payment is not based on the amount that the provider charges. Billed charges generally exceed the amount that Medicare pays the provider. Therefore, a Medicare payment that significantly exceeds the billed charges is likely to be an overpayment.
The deficiencies in the 1,619 incorrect line items included (1) incorrect units of service, (2) a combination of incorrect units of service and incorrect Healthcare Common Procedure Coding System (HCPCS) codes, (3) HCPCS codes that did not reflect the procedures performed, (4) unallowable services, and (5) a lack of supporting documentation.
We recommended that Noridian (1) recover the approximately $5.8 million in identified overpayments, (2) implement system edits that identify line item payments that exceed billed charges by a prescribed amount, and (3) use the results of this audit in its provider education activities. Noridian concurred with our recommendations.
