Medicaid Fraud: Federal Enforcement and Compliance
Key Takeaway for Healthcare Providers: Documentation.
Learn how CMS, HHS OIG, and DOJ address Medicaid fraud, improper payments, documentation deficiencies, and healthcare compliance risks.
Medicaid Fraud Remains a Federal Oversight Priority
The total amount of Medicaid fraud remains unknown, according to a Congressional Research Service report. Importantly, improper Medicaid payments do not automatically indicate fraud or abuse. CMS estimated that 77% of improper Medicaid payments in fiscal year 2025 resulted from insufficient documentation.
DOJ’s New Fraud Division Signals More Aggressive Enforcement – Documentation Is Your Lifeline.
Medical coding errors fall into the broad categories of “fraud” and “abuse.”
- Fraud involves intentional misrepresentation.
- Abuse means “the falsification was an innocent mistake, but representative,” according to the AMA’s Principles of CPT® Coding, ninth edition. An example of abuse could involve coding “for a more complex service than was performed due to a misunderstanding of the coding system,” the text notes.
- Waste is the overuse of services or other practices that directly or indirectly result in unnecessary costs (Intentional?).
Federal and State Medicaid Fraud Enforcement
Multiple agencies oversee Medicaid program integrity. The Centers for Medicare & Medicaid Services (CMS) monitors state programs, while the HHS Office of Inspector General (HHS OIG) conducts audits and oversees state Medicaid Fraud Control Units. The Department of Justice (DOJ) investigates and prosecutes suspected fraud, with healthcare as its top target.
In fiscal year 2025, state Medicaid Fraud Control Units reported recovering $2 billion through criminal and civil cases. Separately, CMS reported $1.5 billion in savings from Medicaid and Children’s Health Insurance Program (CHIP) integrity activities in fiscal year 2024.
CMS has also expanded its fraud-prevention efforts through its Crushing Fraud, Waste, & Abuse initiative. The agency reported that they prevented more than $203 million in potentially improper payments during its first 88 days.
Why Medicaid Compliance Matters
Federal requirements include provider screening, recovery audits, and independent reviews of managed care financial and encounter data. In February 2025, the Government Accountability Office added strengthening Medicaid program integrity to its High Risk List.
Medicaid covered approximately 85 million people and cost an estimated $949 billion in fiscal year 2024, underscoring the program’s scale and the importance of effective oversight.
