The Department of Health and Human Services (HHS) Office of Inspector General (OIG) recently updated its Work Plan, adding several new audits and reviews. The OIG Work Plan forecasts the projects that the OIG plans to implement over the foreseeable future. These new initiatives are a signal of which areas the OIG views as warranting heightened scrutiny, and providers in these areas should take note of the OIG’s actions.
One of the most notable projects on the OIG Work Plan focuses on auditing Medicare claim lines for which the payment exceeds the actual charge. CMS contracts with various Medicare Administrative Contractors (MACs) to, among other things, process and pay claims submitted by providers for items and services covered under Medicare Part B. Generally, Part B payments are based on a fee schedule, prospective payment system, or some other method, rather than a cost or charge basis. In most cases, a healthcare provider’s billed charges exceed the amount that Medicare pays for Part B items and services. Under this Work Plan item, the OIG is focused on Medicare payments that exceed the billed charges, which can be overpayments. Providers should keep a close watch on their Medicare remittance advices or explanation of benefits to be aware of any payments that exceed the corresponding billed charge.
In terms of specific healthcare services, the OIG is turning its attention to hyaluronic acid injections, commonly used to treat knee osteoarthritis. While these injections are widely used for joint pain, there are ongoing questions about whether they are worth the cost and being used appropriately. The OIG’s audit will review Medicare reimbursements for these treatments and whether providers are following proper billing procedures.
