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.

Simply put, Medicare rarely audits dentists because Medicare generally does not cover or pay for dentistry. However, doctors of dental surgery and doctors of dental medicine may perform far more complex surgical procedures than the examinations, cleanings, and fillings that are in the common perception of what a dentist does. Where Medicare does cover and subsequently audits services provided by dentists, the issues raised are generally complex and nuanced. Dentists who bill Medicare should be familiar with the Medicare claims appeal process and some of the issues specific to Medicare coverage of dental services.

The Medicare claims appeal process is a lengthy and complex 5-step process. After the provider receives a determination of claim denials and demand to repay an alleged overpayment, the first appeal step is Redetermination, often before the same Medicare contractor that issues the initial claim denials. Second is Reconsideration before a different Medicare contractor. Third is review by an Administrative Law Judge (ALJ), which may include a hearing – often telephonic – where the provider can present evidence and testimony. Fourth is appeal to the Medicare Appeal Council, the highest adjudicatory body within the Department of Health and Human Services. Fifth is appeal to federal court, which is often limited in scope and may not be appropriate in every case. It can take several months, if not years, for a case to fully work its way through the Medicare claims appeal process, depending on the circumstances.

Medicare audits of services provided by dentists nearly always involve the “dental services exclusion.” By law, the Medicare program does not cover services performed in connection with the care, treatment, filling, removal, or replacement of teeth or structures directly supporting the teeth, which is generally considered to include the periodontium. Procedures on other parts of the mandible or maxilla may be covered where they are medically necessary and meet other coverage criteria. Because of the key distinction between procedures in connection with the teeth and structures directly supporting the teeth, dentists who bill Medicare may consider how they document procedures to clearly document procedures which may not be subject to the coverage exclusion. Procedures on the teeth and periodontium may also be covered where they are inextricably linked to a primary covered service. Further, Medicare contractors may mistakenly interpret the statutory coverage exclusion to mean that Medicare never covers any services provided by a dentist, simply because they are performed by a dentist. However, this assertion is generally inconsistent with the Social Security Act and Medicare guidance.

On March 12, 2024, several senators wrote a letter to the Government Accountability Office (GAO) Comptroller General, requesting an investigation into the policies and procedures CMS has in place to prevent Medicare fraud, waste, and abuse. The senators noted that in 2022, GAO estimated there were $47 billion in improper Medicare payments with $1.7 billion being reclaimed, representing a 2.8% recovery rate.

The senators’ letter was likely prompted by a recent investigation from the National Association of Accountable Care Organizations (NAACOS), which uncovered an alleged fraudulent urinary catheter scheme. NAACOS discovered that ten medical device companies went from billing 15 patients for catheters to over 500,000 patients for catheters within a period of two years. This alleged scheme has been estimated to cost CMS over $2 billion and has garnered significant media attention. Of particular concern to the senators is the fact that NAACOS publicly commented on this issue prior to any announcements from CMS.

The senators noted that this alleged scheme highlights “critical vulnerabilities” within CMS’ fraud, waste, and abuse policies. To this point, they requested that the fraud prevention measures of the Medicare Fraud Strike Force, a team with representatives from the Department of Health and Human Services (HHS), Office of Inspector General (OIG), and Federal Bureau of Investigation (FBI), should be investigated by GAO in order to identify weaknesses and areas for improvement.
