Maine Medicaid Oversight Audit Draws Scrutiny as Federal Repayment Recommendations Remain Open

Maine State Auditor Matt Dunlap’s office flagged a gap in Medicaid oversight. The health department disputes the finding.

The disagreement is receiving renewed attention as questions about Medicaid spending circulate this week.

A separate federal review identified at least $45.6 million in improper payments for children’s autism services.

The Maine Office of the State Auditor reported in its fiscal 2025 audit, issued in March, that the Program Integrity Unit could not document how it selected projects and payment reviews covering Medicaid services. Auditors could not determine whether its monitoring was complete.

Finding 2025-064 classified the problem as a significant deficiency, with no questioned costs. It called for documented procedures and retained evidence supporting the scope of reviews.

The Department of Health and Human Services disagreed, saying the audit confused one unit’s annual plan with the whole agency’s oversight program. It cited other reviews and controls outside that unit.

Auditors stood by the finding, saying those other controls were not documented for the providers and services they identified. The report therefore records an unresolved disagreement, not a finding that all Medicaid payments were fraudulent.

The Health and Human Services Office of Inspector General announced its separate audit in January, covering Maine’s 2023 fee-for-service payments for rehabilitative and community support services for children diagnosed with autism. Each of its 100 sampled enrollee-months included an improper or potentially improper claim line.

Using that sample, federal auditors estimated at least $45.6 million in improper payments, including approximately $28.7 million in federal funds. Those are payment-compliance findings; the audit does not establish that the entire amount was stolen.

The inspector general recommended repayment of the federal share, further review of potentially improper payments, better provider guidance and periodic statewide reviews after payment. Maine conditionally agreed with the repayment recommendation and agreed with the other three.

As of August 31, the federal tracker lists all four recommendations as open and unimplemented, with an update expected November 19. That status does not establish that Maine has taken no interim steps.

The Electronic Code of Federal Regulations sets out the broader duty behind the dispute: a state Medicaid agency must maintain statewide monitoring against unnecessary services and excess payments. That obligation also includes assessing the quality of care.

The regulation covers services across the state plan, rather than allowing the agency to treat payment oversight as an optional activity. Its focus includes both the use of services and the amounts being paid for them.

Checking bills is only part of that assignment. The same provision also requires attention to whether services are appropriate and to the quality of services beneficiaries receive.

Those requirements connect two practical concerns: protecting public money and protecting patients who depend on Medicaid. A payment system can process claims without demonstrating that its safeguards cover every required area.
