CMS OIG

As of February 2026, no comprehensive GAO report on FY2025 improper payments has emerged, but recent HHS-OIG audits reveal continued waste, including $45.6 million in improper Maine Medicaid payments for autism services reported January 21, 2026. Late 2025 OIG findings on NIH oversight gaps and CMS $11.2 billion at-risk contracts reaffirm systemic vulnerabilities in grant and contract management. While some programs show improvement, the pattern of poor oversight across federal agencies persists, validating prior concerns.
