Behavioral Health in Medicaid and the State Children’s Health Insurance Program

Staff presented a draft chapter for the March 2026 Report to Congress with findings from the
Commission’s analytic work using calendar year 2023 Transformed Medicaid Statistical Information
System (T-MSIS) data to measure utilization and spending for Medicaid and Medicaid expansion State
Children’s Health Insurance Program (M-CHIP) enrollees with behavioral health conditions and
intellectual or developmental disabilities (I/DD). The draft chapter begins by providing an overview of
Medicaid enrollees with behavioral health conditions and behavioral health benefits in Medicaid. Then, it
outlines the methodology and limitations for this analysis, and discusses key findings on utilization and
spending for Medicaid and CHIP enrollees with behavioral health conditions, including enrollees with co-
occurring I/DD conditions. The draft chapter included findings for the total population, and then provided
details on children and youth and non-elderly adult enrollees with behavioral health conditions.
