The Oregon Secretary of State’s Office released a 20‑page audit showing that the Oregon Health Plan (OHP) overpaid between $232,000 and $4.1 million because of roughly 650 duplicate identification codes in the state’s eligibility system. The audit examined more than 2 million IDs and found that the duplicate entries led to excess capitation payments to coordinated‑care organizations across the state.
How the error occurred
Auditors discovered that hundreds of enrollee records shared the same system identification code, causing the Oregon Health Authority (OHA) to issue duplicate payments for the same individuals. While OHA has already identified many of these payments and either recouped or adjusted them, the audit confirms that some overpayments remain.
Financial impact
Between 2020 and 2024, Oregon paid $37 billion to coordinated‑care organizations under OHP. The erroneous payments represent a tiny fraction of the program’s total cost – between 0.0004% and 0.0064% of the $64 billion spent on Medicaid statewide during the same period, according to interim Medicaid director Vivian Levy.
State response and corrective actions
Secretary of State Tobias Read emphasized the importance of administering OHP efficiently and in compliance with federal rules. “Overpayments are still overpayments, and any lost federal funding would make it more difficult to care for the Oregonians who need help the most,” he said.
Levy echoed that sentiment, noting that OHA’s Managed Care Reconciliation Team maintains strong systems and that the agency is committed to correcting duplicate‑ID errors. The health authority accepted all auditor recommendations, which include improving eligibility‑staff training, expanding review of identification codes, returning excess funds to the federal government, and establishing a quality‑control process to prevent future duplication.
Broader context
The audit arrives as Oregon prepares to implement resource‑intensive work‑requirements and heightened eligibility reviews mandated by the GOP‑backed 2025 federal tax and spending law. Critics, including Democrats and some eligibility workers, warn that these changes could make it harder for qualified residents to receive benefits.
Nevertheless, OHA officials stress that the overpayment issue is isolated and that the agency remains a responsible steward of taxpayer dollars. The small percentage of duplicate payments underscores the overall robustness of the state’s Medicaid administration.
Previous audit findings
This is not the first audit flagging payment irregularities. A March review identified a separate OHP program for higher‑income adults that may have improperly distributed up to $15 million in benefits.
State officials say they are taking both audits seriously and will continue to refine processes to protect federal funding and ensure that OHP delivers reliable health coverage to the one‑in‑three Oregonians who rely on it.
