Series 4: Building Medicaid Redetermination Infrastructure for Expansion Adults

The move to semi-annual Medicaid redetermination for 18.5 million expansion adults will strain state systems, MCOs, providers, employers, and community organizations. Unlike annual renewals for other populations, these cycles require verifying income, household composition, work compliance, and exemptions twice yearly, creating either large processing surges or continuous engagement. States must rapidly expand technology, staffing, and communication capacity, while MCOs adapt workflows and employers prepare for bulk verification. Providers face heavy documentation burdens and navigation support must scale quickly.

Semi-annual redetermination for Medicaid expansion adults is more than an administrative hurdle, it’s a recurring crisis for vulnerable populations, especially those with autism, intellectual and developmental disabilities (IDD), and their caregivers. These individuals often fall into a gap: too “mild” for SSI automatic exemptions, yet burdened with intensive work verification and documentation requirements that their conditions make difficult to complete. Executive function challenges, episodic health crises, and communication barriers compound the burden, while caregivers must repeatedly re-document permanent disabilities and constant care responsibilities. Standard processes assume neurotypical capacity and stable circumstances, creating systemic failure when those assumptions don’t hold. Missed deadlines lead to coverage loss, medication interruptions, and destabilization of family systems. Solutions must include automatic exemptions for SSI recipients, supported decision-making, simplified language and visual materials, presumptive coverage during documentation delays, annual rather than semi-annual renewals for permanent conditions, and provider attestation integrated into clinical workflows. Without these accommodations, the policy will predictably produce coverage loss and health crises, turning a system meant to protect into one that punishes those least able to comply.

Building the infrastructure for semi-annual redetermination is a massive coordination challenge across states, MCOs, employers, providers, and community organizations. States must upgrade eligibility systems, integrate work and exemption data, expand staffing, and scale appeals capacity within just 12 months, while MCOs develop workflows for proactive outreach and documentation support. Employers need bulk verification processes, providers require streamlined exemption renewal integrated into clinical care, and community organizations must scale navigation services. Success depends on pragmatic, aligned investments and minimum viable systems at launch, with enhancements over time. Delay will lead to predictable coverage loss, health crises, and systemic breakdown, making urgent collaboration across all stakeholders essential before January 2027.
