Idaho lawmakers hear broad Medicaid budget increases, hospital-assessment and behavioral-health implementation costs

A Division of Medicaid budget presentation at the Joint Finance-Appropriations Committee on Feb. 26 detailed large supplemental and ongoing requests tied to caseload growth, provider-rate changes and technical adjustments to how Idaho draws federal matching dollars.

Alex Williamson, budget and policy analyst with Legislative Services, told the committee the division administered five Medicaid benefit plans and that Medicaid appropriations and payments have grown substantially: the department appropriated about $4.56 billion for fiscal 2024 and expended roughly $4.27 billion.

The presentation outlined five fiscal‑2025 supplemental requests and a slate of fiscal‑2026 enhancements the department and analysts say are largely driven by expected utilization and several one-time and ongoing implementation costs. The supplemental items include money for federally required reviews, system configuration tied to the Idaho Behavioral Health Plan (IBHP), a capitation-rate change for managed‑care plans, and a request to process a larger hospital assessment tied to upper payment limit (UPL) calculations.

Why it matters

Committee members pressed department officials on why costs exceeded earlier forecasts, what parts of the spending are ongoing, and how the state can improve forecasting and vendor performance.

Key budget items and department explanations

• External quality review (EQR): Williamson said Idaho must complete an annual EQR of its managed care organizations. After failed procurements and a market shift, the department requested roughly $1.35 million (noted as a one‑time then corrected to ongoing in budget materials) to onboard a vendor and complete required reviews for behavioral health, dental and Medicare‑Medicaid dual plans.

• IBHP system configuration and capitation: The department requested one‑time funds to complete information‑technology work to onboard a new IBHP vendor and to implement capitation‑rate increases. Williamson described a $695,500 one‑time request for system configuration and an additional $108.8 million one time (federal funds) for capitation-rate…
