HHS OIG Discovers What Medicare Providers Have Long Known
The US Department of Health and Human Services (“HHS”) Office of Inspector General (“OIG”) recently released a report wherein it found what Medicare providers have long known, that Medicare Administrative Contractors (“MACs”) frequently commit significant errors and do not comply with Medicare requirements when they conduct audits of Medicare providers.
Specifically, OIG reviewed MAC audits of Medicare costs reports and found that, for federal fiscal years 2019–2021, each of the 12 MAC jurisdictions failed to comply with the contract requirements for audit and reimbursement desk review and audit quality for at least 1 of the 3 years. The Centers for Medicare & Medicaid Services (“CMS”) also identified 287 total audit issues among all MAC jurisdictions during that period, including MACs not performing proper reviews; inadequate review of graduate medical education and indirect medical education reimbursement; improper review of allocation, grouping, or reclassification of charges to cost centers; improper calculation and reimbursement for nursing and allied health programs; and inadequate review of bad debts.
Issues with MAC reviews are nothing new to Medicare providers. In addition to auditing cost reports, MACs also audit claims under Medicare fee-for-service and perform the first level of claims appeals, referred to as Redetermination. In regard to audits, MACs are often criticized for misinterpreting criteria, applying the wrong criteria, using nurse reviewers with little to no experience in the clinical area under review, and taking excessive amounts of time to complete reviews. However, MAC audit issues might not present such a significant issue if MACs did not also perform the first level of appeal – Redetermination – of their own audits.
