CMS Doubles Down on Medicaid Fraud Detection: What’s Next?
The Centers for Medicare & Medicaid Services (CMS) is intensifying its focus on identifying and preventing “fraud, waste and abuse” within Medicaid, a trend that’s been building since the establishment of the Center for Program Integrity (CPI) in 2010. This isn’t simply a “pay and chase” approach; CMS is increasingly leveraging data analytics to proactively detect and deter improper payments. A recent collaborative letter to states in November 2025 signals a renewed push for federal and state partnerships in this effort.
The Rise of Data-Driven Oversight
The CPI’s core mission is to strengthen integrity programs and move away from reactive measures. This shift is exemplified by the February 14, 2026, release of a provider-level spending dataset. While intended to help identify unusual billing patterns, the dataset’s limitations highlight the complexities of interpreting Medicaid spending data.
Decoding the Recent Medicaid Spending Data
The newly released dataset includes key identifiers like National Provider Identifiers (NPIs) for both billing and servicing providers, procedure codes (HCPCS), monthly data, beneficiary counts, claim counts and total payments. It covers fee-for-service and managed care spending from 2018 to 2024. However, crucial data points are missing.
Notably excluded are institutional records and prescription drug costs – representing a significant portion of overall Medicaid spending (hospital care alone accounts for 37%). The data lacks information on enrollment numbers, benefit packages, payment rates, diagnoses, and place of service, all of which are critical for accurate analysis.
Potential Pitfalls in Data Interpretation
CMS acknowledges the potential for misinterpretations. The agency’s example highlighting personal care spending as a major outlier illustrates this point. The broad definition of “personal care” – encompassing services from 15 minutes to a full day – makes it demanding to compare directly with more narrowly defined procedures like psychotherapy visits, which are categorized by length (30, 45, or 60 minutes).
Similarly, comparing providers is complicated by the fact that some are individual practitioners, while others are large government agencies that both administer and deliver Medicaid benefits. Data quality concerns, as highlighted in CMS’s own “data quality atlas,” also pose a challenge. Six states had unusable spending data in 2024, and another 16 had data of “high concern.”
The Impact of the Pandemic and Policy Shifts
Analyzing Medicaid spending trends from 2018-2024 requires acknowledging the disruptive influence of the COVID-19 pandemic. Increased enrollment during the continuous enrollment period and a greater awareness of unmet needs for behavioral health and long-term care led to significant changes in service utilization and spending. State-level policy decisions regarding coverage, eligibility, and provider payment rates further complicate the picture.
Future Trends in Medicaid Program Integrity
Several key trends are likely to shape the future of Medicaid program integrity:
1. Enhanced Data Analytics and AI
CMS is actively integrating artificial intelligence (AI) and machine learning to refine fraud detection algorithms. Expect more sophisticated predictive analytics to identify high-risk providers and claims. This will likely involve analyzing patterns across multiple data sources, not just the newly released dataset.
2. Increased Collaboration with States
The collaborative letter to states signals a commitment to strengthening partnerships. This could involve sharing best practices, providing technical assistance, and coordinating enforcement efforts. The Medicaid Integrity Institute will likely play a central role in this collaboration.
3. Focus on Managed Care Oversight
CPI is prioritizing oversight of Medicaid managed care organizations. This reflects the growing role of managed care in Medicaid and the demand to ensure accountability for taxpayer dollars. Expect increased scrutiny of risk adjustment practices and quality metrics.
4. Addressing Marketplace Agent/Broker Fraud
CMS is also focusing on problematic practices among agents and brokers in the Health Insurance Marketplace. This includes investigating deceptive marketing tactics and enrollment fraud.
5. Expanded Data Transparency (with Caveats)
The release of the provider-level spending dataset suggests a broader trend toward data transparency. However, CMS will need to address data quality concerns and provide sufficient context to avoid misinterpretations. Future data releases may include additional variables and more detailed documentation.
