In 2023, the total Medicaid expenditure across the United States reached $880 billion. Among the states with the highest spending on individuals enrolled in Medicaid across multiple states, California topped the list at $134 million, followed by Washington at $65 million.
Duplicate Medicaid payments occur when an individual is simultaneously enrolled in more than one state Medicaid programs. Duplicate enrollments normally occur when program beneficiaries relocate or do not have stable housing. In Oregon, for example, those with simultaneous Medicaid enrollments were found to be twice as likely to be experiencing homelessness compared to the general Medicaid population in Washington.
When beneficiaries are enrolled in more than one state's Medicaid system, the government improperly pays for their coverage multiple times-- without providing any extra benefits. Between 2019 and 2022, Oregon alone spent $445 million on Medicaid payments for duplicate enrollees. A report from Oregon's state auditors found that roughly 3% of Medicaid recipients in the state were also registered in another state's program.
The problematic data tracking system used to detect duplicate enrollments is a considerable hurdle in correcting this issue. The Social Security Administration's records are at times incorrect, making it troublesome for state agencies to pinpoint persons enrolled in multiple programs. Dealing with this issue requires both internal and external improvements. Internally, Washington's Auditor's Office advises that the Health Care Authority and the Department of Social and Health Services enhance communication to better track people who may have moved out of state. If someone leaves a state-run program due to relocation, that information should be shared across relevant agencies to prevent continued Medicaid enrollment in Washington. Externally, stronger coordination between states is necessary. Since individuals who enroll in multiple Medicaid programs often transfer to neighboring states, it would be beneficial for state agencies to work together and cross-check enrollment records. Washington and Oregon have settled on a strategy that includes efforts to reclaim funds spent on duplicate enrollments, partnering with the U.S. Treasury to launch a pilot program, implementing national data verification methods, and obtaining funding for additional staff dedicated to data matching.
One of the most useful data-driven solutions for determining active other coverage in the Medicaid program has emerged from the private sector. Syrtis Solutions (Syrtis) has launched a technology-based solution to aid the program in identifying third party liability (TPL) before medical and Rx claims are paid improperly. With the help of Syrtis Solutions and their proprietary ePrescribing data, Medicaid plans can now identify other coverage on utilizing members in real-time. Consequently, plans can avoid duplicate payments and other improper payments.
Medicaid and other taxpayer-funded programs need greater efficiency, quality data, and stringent oversight to protect program resources from duplicate payments and other improper payments. Duplicate Medicaid enrollments drain program resources, and with Washington alone incurring a $8.6 million cost, critical action is needed to stop further waste and ensure that program dollars are used to help the nation's most vulnerable populations.
