The Centers for Medicare & Medicaid Services (CMS) announced a funding opportunity, made possible by the American Rescue Plan, to help states strengthen system capacity to provide community-based mobile crisis intervention services for those with Medicaid. The $15 million funding opportunity is available to state Medicaid agencies for planning grants to support developing these programs. This funding opportunity provides financial resources for state Medicaid agencies to assess community needs and develop programs to bring crisis intervention services directly to individuals experiencing a mental health or substance use related crisis outside a hospital or facility setting. These services may include screening and assessment, stabilization and de-escalation, and coordination of referrals after the initial treatment.
