Medicaid Managed Care Program
Learn how the AI-generated research projects were createdOverall Conclusion
The audit found material weaknesses in MEDES controls that allowed improper and potentially preventable capitation payments to be issued, particularly for bypassed and out-of-state and incarcerated participants. While MEDES updates have improved functionality for new participants, they do not automatically correct past issues, and recoupment of overpayments is limited. The report emphasizes the need for stronger system controls, tracking, and timely redeterminations, as well as ongoing vendor coordination to mitigate risks in the Medicaid Managed Care program.

Audit Scope
Scope and Methodology: The scope of the audit included evaluating (1) DSS management's procedures to ensure reliable MC encounter data, (2) DSS management's techniques to provide oversight of the program, (3) policies and procedures, and (4) other management functions and compliance requirements in place during the period July 2016 to June 2019. Due to MEDES system control limitations and complexities rising from the DSS's long-term resolution efforts in the MEDES, we also observed activity beyond June 2019 for further comprehension and to assess significance. The audit tested controls related to four main areas: 1) Eligibility Bypass, 2) Indicator Control, 3) Out-of-State Participants, 4) Incarcerated Participants. The data sources included MMIS capitation payments and encounter data, MEDES eligibility records, and data from the Missouri Department of Corrections and Missouri Department of Health and Senior Services. The audit notes the existence of MEDES updates post-2019, the participation of external factors such as the 2020 public health emergency and FMAP changes, and cross-system data flows (MMIS and MEDES). The scope encompassed July 2016 through June 2019 with additional activity for comprehension through 2020, to understand ongoing resolution efforts and potential ongoing risks.
Key Findings Summary
Eligibility Bypass: The Department of Social Services improperly issued capitation payments on behalf of participants whose eligibility had been activated (and remained active) in MEDES via a manual bypass process, which prevented MEDES controls from deactivating eligibility and discontinued payments when participants became ineligible.
Indicator Control: Weaknesses in the MEDES 'indicator' control and related manual tracking allowed overpayments and potentially preventable capitation payments to continue due to triggers that do not accurately reflect MHABD eligibility status.
Out-of-State Participants: DSS improperly issued capitation payments for participants who were no longer Missouri residents due to MEDES control limitations in deactivating eligibility when participants moved out of state.

AI Scope Summary
To assess the effectiveness of Missouri's Medicaid Managed Care program controls and data management, focusing on the reliability of encounter data, oversight capabilities, legal compliance, and IT controls during July 2016 through June 2019, with consideration of activities extending beyond June 2019 due to MEDES limitations and the public health emergency.
AI-Generated Insight
This Missouri State Auditor report on the Medicaid Managed Care Program highlights critical weaknesses in eligibility management and data controls, particularly around MEDES bypass processes and indicator tracking. It underscores the dependence on accurate encounter data and automated controls for oversight, and the challenges of coordinating across systems and vendors to prevent improper payments in Medicaid managed care.
