Medicaid Waivers for Youth with Severe Emotional Disturbance: Associations with Public Health Coverage, Unmet Mental Health Needs & Adequacy of Health Coverage.

Home and Community-Based Services (HCBS) Medicaid waivers for Serious Emotional Disturbance (SED) extend Medicaid eligibility to youth who otherwise would be financially ineligible and finance a broad array of highly specialized mental health services specific to the needs of youth with SED. This study examines whether these policies are associated with greater public health insurance coverage among youth with severe mental health diagnoses. It also assesses, among youth with severe mental health diagnoses who have public health coverage, whether waiver policies are associated with reduced reports of unmet mental health treatment need and increased reports of adequate mental health coverage. Analysis uses CMS reported data on state HCBS Medicaid waivers in conjunction with data from the National Survey of Children's Health for the years 2016 through 2018. Multi-level, fixed-effects logistic regression models demonstrate that living in a state with an HCBS Medicaid waiver is associated with significantly increased odds of having public insurance among children with concurrent private health coverage (OR 1.89), reduced odds of unmet mental health needs among youth with public coverage (OR 0.45), but not significantly associated with reported adequacy of mental health insurance coverage.
