The STOP Medicaid Fraud Act of 2026 requires states to implement electronic verification systems for two types of Medicaid services: non-emergency transportation and applied behavior analysis services, effective January 1, 2027. These electronic systems must verify key details about the services provided, similar to existing requirements for other Medicaid services. States that fail to comply must submit a corrective action plan within 90 days and come into full compliance within one year of receiving notice from the federal government. The requirement does not apply to states that already have their own electronic verification systems in place for these services. The legislation aims to reduce fraud and improve oversight by requiring digital documentation that confirms when and how these services are actually delivered to Medicaid beneficiaries.
