The Iowa Department of Human Services announced that all 15 regions under the state's Mental Health and Disability Services Redesign plan will begin operating Tuesday. The plan, approved by the Legislature in 2012, is intended to create a regional base of services in which counties pool resources to meet a statewide set of standards. The regions are required to provide core services, including treatment, 24-hour crisis services, support for community living, and employment and recovery services. The regions' plans for service delivery were reviewed and revised by the department this month. Counties have historically covered non-Medicaid mental health treatment services, and many offered services through county homes. Under the new Iowa Health and Wellness Plan, adults ages 19 to 64 who meet income requirements are eligible for Medicaid-funded mental health treatment services they may not have been eligible for before.
