Report Materials
Why OIG Did This Audit
- Medicare providers are required to submit to their Medicare administrative contractor (MAC) annual cost reports, which are financial documents that convey the provider’s costs associated with providing services to Medicare enrollees. MACs use them to determine the final amount of Medicare program reimbursement due providers for their cost reporting period (the final settlement of the cost report).
- MACs may audit a provider’s cost report after performing a mandatory desk review to further verify compliance with the law, regulations, and Medicare manual instructions relating to the final settlement of the cost report.
- CMS’s primary goal is for the MACs to arrive at correct final settlements of the cost report. If there is an error made in the final settlement, the cost report final settlement may be reopened and adjusted to correct for the error. We performed this audit of one MAC, Novitas Solutions, Inc. (Novitas), to determine whether Novitas reopened and corrected cost report final settlements because of obvious errors in their audits.
What OIG Found
Novitas reopened 8 of 281 (2.8 percent) audited cost reports to correct the final settlements that contained obvious errors. These 8 audited cost reports required 10 reopenings because of human errors by Novitas.
- As a result of these 10 errors, the reopened cost reports resulted in corrected final settlements to providers totaling $1.1 million in net overpayments, consisting of $1.4 million in overpayments and $285,076 in underpayments.
- Auditors and supervisors required additional education on the criteria and audit requirements applicable to certain payments and bad debts. Novitas’ procedures for review by supervisors did not detect the incorrect audit adjustments.
- The risk exists that delays in the finalization of audited cost reports could prevent some Medicare funds from being expended in the most efficient and effective ways.
What OIG Recommends
We recommend that Novitas:
- develop and deliver additional education to auditors and audit supervisors regarding applicable criteria and review requirements and
- develop and implement enhanced procedures so that supervisors are better qualified to detect incorrect audit adjustments.
Novitas agreed with both of our recommendations and described actions it has taken to address them.
