Oregon Health Authority: Medicaid Duplicate IDs Put Federal Funding at Risk
Learn how the AI-generated research projects were createdOverall Conclusion
OHA agreed with all recommendations.
Source Document
Audit Scope
This audit focuses on Medicaid recipients who had multiple system IDs and concurrent capitation payments made from 2020 to 2024. A capitation payment is a fixed monthly amount OHA pays to Coordinated Care Organizations (CCOs) for each recipient regardless of how many services a recipient uses.
Key Findings Summary
Federal funding could be at risk if OHA does not follow federal rules.
OHA made duplicate capitation payments for the same recipient during the same time.
We performed data matches between all Medicaid recipients from 2020 to 2024 to identify potential duplicate recipients where capitation payments were made concurrently.

AI Scope Summary
This audit evaluated whether the Oregon Health Authority paid duplicate Medicaid capitation payments to the same recipient concurrently from 2020 to 2024, identified 645 potential duplicates with $230,252 in overpayments and projected total duplicate payments ranging from $232,000 to $4.1 million across the program, and concluded that corrective actions and strengthened data controls are needed to protect federal funding; the Oregon Secretary of State’s Audits Division issued recommendations that OHA agreed to.
AI-Generated Insight
The audit identifies duplicate Medicaid capitation payments to the same recipient during 2020–2024, highlighting risks to federal funding and underscoring the need for data governance, staff training, and system improvements to prevent and detect duplicates and to ensure proper reconciliation with federal requirements.
Audit Objectives
To determine whether the Oregon Health Authority (OHA) made duplicate payments for the same recipient at the same time.
Audit Findings (4)
Federal funding could be at risk if OHA does not follow federal rules.
OHA made duplicate capitation payments for the same recipient during the same time.
We performed data matches between all Medicaid recipients from 2020 to 2024 to identify potential duplicate recipients where capitation payments were made concurrently.
Testing identified $230,252 in overpayments; projections estimate OHA made between $232,000 and $4.1 million of duplicate capitation payments for the entire Medicaid program between 2020 and 2024.
Recommendations (5)
Review the other IDs that were not detail tested to determine if they are duplicates and whether overpayments occurred, and remit the federal portion of the overpayments back to the federal government.
Recoup duplicate payments from Coordinated Care Organizations using the capitation reconciliation process.
Provide specific training to eligibility workers on best practices for researching applicants and potential matches.
Develop future system enhancements that will reduce the manual research currently performed by eligibility workers.
Design and implement a quality control process to better prevent and detect duplicate IDs, including a mechanism to identify capitation payments once duplicate IDs are identified, and using the established capitation reconciliation process to remit the federal portion of overpayments in compliance with federal regulations.
