CMS Reports $95.5 Billion In Improper Payments Across Federal Healthcare Programs

Healthcare organizations face continued scrutiny as federal oversight programs identify documentation gaps that drive billions in payment errors.

Understanding The Fiscal Year 2025 Numbers

The Centers for Medicare and Medicaid Services released its fiscal year 2025 improper payment estimates, revealing significant documentation challenges across federal healthcare programs. While the Medicare Fee-for-Service improper payment rate decreased to 6.55 percent, or $28.83 billion, other programs saw increases that warrant attention from healthcare financial leaders.

Medicare Part C improper payments rose to 6.09 percent, or $23.67 billion, up from 5.61 percent in fiscal 2024. The Medicaid program’s improper payment rate climbed to 6.12 percent, or $37.39 billion, compared to 5.09 percent the previous year. These figures represent payments that failed to meet program requirements, not necessarily fraud or abuse.

According to CMS data, the primary driver of improper payments is insufficient documentation. In Medicaid, 77.17 percent of improper payments resulted from documentation gaps. For CHIP, that figure reached 56.07 percent.

What Drives Improper Payment Classifications

An improper payment does not automatically indicate fraudulent activity. The Payment Integrity Information Act of 2019 defines significant improper payments as exceeding $10 million or 1.5 percent of program payments, or totaling $100 million or more. Under these thresholds, payments are classified as improper when reviewers cannot verify compliance with program requirements.

Common scenarios include missing documentation, insufficient records to substantiate services rendered, or administrative errors where the correct payment was made to the right recipient but procedural requirements were not followed. In the Affordable Care Act’s Advance Premium Tax Credit program, 43 percent of improper payments fell into this “technically improper” category.

For healthcare organizations managing revenue cycle operations, these findings underscore the critical importance of complete and accurate documentation systems. When reviewers cannot verify that services were medically necessary or properly delivered, even legitimate payments may be classified as improper.

The Documentation Challenge For Healthcare Providers

Medicare Part C saw most improper payments attributed to situations in which Medicare Advantage organizations could not provide documentation substantiating the beneficiary’s diagnosis data submitted for payment. This pattern reflects a broader challenge facing healthcare organizations: maintaining documentation systems that meet increasingly rigorous federal review standards.

Documentation requirements have grown more complex as payment models shift toward value-based care and risk adjustment. Providers must now maintain records that not only justify medical necessity but also support the accuracy of diagnosis codes used in payment calculations.

For hospitals and health systems, this means investing in staff training, clinical documentation improvement programs, and technology systems that capture complete patient information at the point of care. The cost of these investments must be weighed against the financial risk of payment recoupments and the administrative burden of responding to audits.

Medicaid Redeterminations Drive Rate Increases

The increase in Medicaid and CHIP improper payment rates reflects the resumption of normal eligibility verification processes after the COVID-19 public health emergency. States restarted eligibility redeterminations and provider revalidation requirements in April 2023, creating administrative challenges as millions of beneficiaries required updated documentation.

Healthcare organizations serving Medicaid populations should anticipate continued scrutiny around eligibility verification and documentation standards. Ensuring systems are in place to verify patient eligibility at every encounter can prevent claim denials and reduce the risk of payment recoupments.

Organizations can strengthen their compliance programs by implementing regular internal audits that mirror federal review methodologies. Our healthcare advisory team helps hospitals and medical practices develop documentation standards that satisfy federal requirements while supporting efficient clinical workflows.

Medicare Fee-For-Service Shows Continued Improvement

One positive trend in the fiscal 2025 data: Medicare Fee-for-Service improper payments remained below the 10 percent compliance threshold for the ninth consecutive year. The rate declined from 7.66 percent to 6.55 percent, suggesting that provider education and enhanced review processes are having an impact.

This improvement demonstrates that focused attention on documentation and billing accuracy can produce measurable results. Healthcare organizations should view these federal reports not as punitive measures but as opportunities to identify operational improvements that strengthen financial performance.

Action Steps For Healthcare Financial Leaders

Healthcare CFOs and revenue cycle directors should use these findings to evaluate their own documentation and billing processes. Key questions include: Does your organization have adequate staff training on documentation requirements? Are clinical documentation improvement specialists integrated into patient care workflows? Do your internal audit processes identify documentation gaps before external reviewers do?

Regular self-audits using the same criteria federal reviewers apply can help organizations identify vulnerabilities and implement corrective measures proactively rather than reactively.
