This resolve directs the Department of Health and Human Services to, in its rules governing reimbursement for crisis resolution services, develop a reimbursement model for those services that is designed as an annual cost reimbursement model rather than a per encounter basis model. The reimbursement model must be designed to fully cover staffing and operational costs for crisis resolution services to operate 24 hours per day, 7 days per week. The services affected by this resolve are those services that are described by the MaineCare Benefits Manual as designed to offer immediate crisis-oriented services to an individual experiencing a crisis related to mental or behavioral health or social relationships or a crisis related to an intellectual disability, autism or related condition. Crisis resolution services also include services offered for co-occurring substance use conditions. The resolve also directs the Department of Health and Human Services to establish the Crisis Resolution Services System Study Group to conduct a study to evaluate and recommend funding sources for crisis resolution services. The department must submit a report of the study group's findings to the joint standing committee of the Legislature having jurisdiction over health and human services matters by January 15, 2025.
