Audit Highlights Improper Medicaid Payments

A recent audit by the Office of Inspector General (OIG) for the U.S. Department of Health and Human Services (HHS) has brought to light substantial issues with the New York State Department of Health (NYSDOH), uncovering improper claims for federal Medicaid funds. The audit spans from October 2016 to September 2019, during which New York improperly claimed $7.8 million in federal funds for payments made to Managed Care Organizations (MCOs) on behalf of enrollees whose eligibility status did not meet federal requirements. 

This revelation underscores the persistent problem of improper Medicaid payments—an issue that has plagued both state and federal healthcare systems for years, draining significant financial resources. The audit has broader implications, as it highlights systemic weaknesses in Medicaid oversight and calls for a more robust and efficient system to track and verify eligibility statuses. 

What the Audit Found 

The OIG’s audit found that New York claimed federal funds for individuals who were assigned to incorrect eligibility groups. These enrollees included those who were ineligible, such as individuals enrolled in both Medicaid and Medicare, as well as those who fell into other ineligible categories. At the root of the issue was inconsistent record-keeping and a lack of accurate data reconciliation. 

The discrepancies in New York’s Medicaid system mirror problems seen in other states, where a lack of oversight and proper verification systems has led to significant improper payments. In previous audits, the OIG found that improper Medicaid payments across various states are estimated to exceed $36 billion annually, exacerbating financial pressures on both state and federal budgets. 

The Impact of Improper Medicaid Payments 

Improper Medicaid payments are not a new phenomenon. They have been a longstanding issue, resulting from the complexity of Medicaid eligibility requirements and the inherent challenges in managing a program that serves millions of people. For the federal government, the issue represents a significant drain on resources, particularly at a time when the healthcare system is already struggling to keep up with increasing demands. 

Improper payments can take several forms. The most common type is overpayment, which can happen when payments are made for services rendered to ineligible individuals. This could occur when someone is wrongly categorized, as seen in the New York audit, or when a payment is made for a deceased individual or someone no longer eligible for Medicaid. 

Underpayment, while less common, is also an issue. These payments happen when providers do not receive full compensation for services rendered, often due to administrative errors or issues with documentation. In some cases, payments are made, but the proper regulations or statutes are not followed, leading to legal and financial implications for the state and federal governments. 

The ripple effects of improper Medicaid payments are far-reaching. For one, they reduce the pool of available resources for eligible recipients, potentially limiting access to care for the millions of Americans who rely on Medicaid. Additionally, they strain the administrative capacity of both state and federal agencies, which must divert attention and resources toward addressing these discrepancies rather than focusing on improving healthcare delivery. 

Structural Issues and Oversight Gaps 

One of the primary reasons for improper Medicaid payments is weak oversight at the state level. The OIG’s audit of New York found that the state did not have effective systems in place to consistently verify eligibility statuses, leading to ongoing discrepancies in payments to MCOs. This issue is not unique to New York; other states have also been flagged for similar failures in their Medicaid systems. 

In many cases, states lack the technological infrastructure to accurately match data and reconcile eligibility information with payments. As Medicaid serves a large and diverse population, the complexity of eligibility requirements—especially in states with managed care programs—adds another layer of difficulty to ensuring accuracy. 

OIG has recommended that states, including New York, implement better data-matching technologies and conduct regular audits to catch discrepancies before they become systemic. However, many states have been slow to adopt these changes, in part due to budget constraints and the cost of upgrading legacy systems. 

NYSDOH’s Response and Federal Involvement 

In response to the OIG’s findings, the NYSDOH acknowledged that errors were made but defended its overall payment system, noting that most payments were accurate. The department has committed to reviewing the OIG’s recommendations and taking corrective actions to prevent future occurrences of improper payments. While acknowledging its shortcomings, the NYSDOH emphasized that steps have already been taken to improve the system and reduce the likelihood of such mistakes in the future. 

At the federal level, the Centers for Medicare and Medicaid Services (CMS) has also taken steps to enhance program integrity. These steps include introducing more stringent rules around eligibility verification and the reconciliation of managed care payments. However, as the OIG audit revealed, implementation at the state level remains a significant hurdle. The complex nature of Medicaid, combined with the diversity of state-level healthcare systems, makes it difficult to apply federal rules uniformly across the board. 

For CMS, ensuring program integrity is a top priority, but without strong collaboration between federal and state agencies, improper payments will continue to drain resources. Strengthened oversight, improved technology, and regular audits are key to addressing these issues. 

The Larger Trend of Improper Payments 

The problems identified in the OIG audit of New York reflect a larger trend of improper payments within the U.S. healthcare system. In March 2023, the U.S. Government Accountability Office (GAO) reported an estimated $236 billion in improper payments during the fiscal year, with more than $100 billion coming from Medicare and Medicaid alone. 

While some progress has been made in reducing improper payments, they remain a significant financial burden. For example, the GAO reported that payment errors under Medicaid dropped by $30 billion from the previous year. However, improper payments still remain higher than they were before the COVID-19 pandemic, and much work remains to be done to bring them under control. 

What Needs to Change? 

To prevent improper payments from continuing to drain resources, both state and federal governments must take decisive action. First and foremost, states need to implement stronger oversight mechanisms to ensure that eligibility verification processes are accurate and up-to-date. This means investing in better technology for data matching and reconciliation and conducting regular audits to catch discrepancies before they lead to significant financial losses. 

Additionally, CMS must work more closely with state agencies to ensure that federal rules are being followed consistently across all states. While Medicaid is a federal program, it is administered by the states, which means that collaboration between federal and state entities is essential to ensure program integrity. 

In New York, the OIG has recommended that NYSDOH refund the $7.8 million in federal funds that were improperly claimed and take steps to strengthen its eligibility verification systems. For other states, the audit serves as a cautionary tale about the importance of strong oversight and the risks of inadequate data reconciliation. 

With billions of dollars at stake, addressing these discrepancies is essential to ensuring that Medicaid remains a viable program for the millions of Americans who rely on it for healthcare coverage. Through stronger oversight, better technology, and closer collaboration between federal and state agencies, the healthcare system can reduce improper payments and ensure that resources are being used effectively.
