Mental Health & Substance Use


Trillium serves approximately 26,250 adults and children annually who seek services to address Mental Health and Substance Use (MH/SU) challenges.  To ensure people receive the services they need in a timely manner, we employ clinically trained and licensed staff to manage and authorize those services.

Trillium requires priority admission to all women who are pregnant and injecting drugs, pregnant and using substances and other individuals who are injecting drugs.

Care Coordination

Care Coordination is a major function of the MCO.  It is a proactive, person-centered, assessment-based approach to integrating medically necessary behavioral health services, primary health care and natural and community social support services. 

Individuals who need intensive services are assigned to a Care Coordinator.  This includes individuals recently hospitalized with MH/SU diagnoses and children at risk of or placed out-of-home. Most Care Coordination functions occur telephonically. Our team of Care Coordinators assists individuals and families in the following ways:

  • Provide education regarding MH/SU, including recovery-oriented supports and natural or community supports;
  • Ensure members receive a quality, comprehensive assessment that identifies symptoms and diagnosis, how those symptoms affect daily life, and the person’s strengths and treatment needs;
  • Link to community and natural supports;
  • Monitor the Person-Centered Plan or Treatment Plan;
  • Request and monitor the Crisis Plan developed between the provider and the member;
  • Assist in the discharge planning process for individuals hospitalized for behavioral health reasons to ensure success in their recovery;
  • Link the member to needed psychological, behavioral, educational, and integrated health care services;
  • Assist with coordination of all Medicaid benefits, including primary care engagement;
  • Monitor the treatment provided ensuring the health and safety of the member, the person’s satisfaction with care and services, and that services are delivered as specified in the plan;
  • Collaborate to address obstacles to successful recovery

    Utilization Management (UM)

    We have a team of Master’s level licensed clinicians, called UM Care Managers, who review Treatment Authorization Requests (TARs) for medical necessity. In most cases, this is done prior to the provider delivering a service to an member. During the review process our UM Care Managers follow guidelines set forth by state governing agencies and Trillium.

    Resources our Care Managers use include:
