Frequently Asked Questions (F.A.Q.)

  1. Why is Halifax County joining Trillium? 
    In August 2021, the Halifax County Board of Commissioners voted to disengage from Cardinal, and asked for permission to join Trillium. The Trillium Governing Board voted to accept this request on August 9, 2021. On September 16, Secretary Cohen with the Department of Health and Human Services approved Halifax County’s request and stated the launch date would be December 1. 
  2. How many members will join Trillium’s catchment area?
    Trillium will work with DHHS and Halifax County to determine the number of individuals who live in Halifax County, receive services for I/DD or behavioral health, have not been placed on the Standard Plan, and will transition to Trillium.
  3. Will Trillium have an office in Halifax County? Which region will Halifax be considered a part of?
    Trillium serves members through its Provider Network, local agencies and practitioners who are based in the communities where they provide services. Members and recipients can view this Network through our online Provider Directory or by calling our Member and Recipient Service Line at 1-877-685-2415. Halifax County will be part of the Northern Region with Trillium and the Halifax regional director, System of Care Managers, and other Trillium staff will work directly with Halifax County agencies and partner offices.
  4. When will I get new paperwork about this change?
    We start mailing welcome letters to Halifax County members in November. The letters will include the Notice of Privacy Practices with Trillium. Members can view the Member & Recipient Handbook.  When members on Medicaid receive a new Medicaid card from the state, it will have Trillium’s name on it. You do not have to do anything at this time.
  5. Will my care manager, provider, or services change before December 1??
    While a new Trillium Care Manager may reach out to you before December 1, if you have a Care Manager with Cardinal you will continue to use them until then. You may call Trillium at 1-866-998-2597 to ask about Care Coordination if you are not notified by the new Trillium Care Manager. As long as your provider completes the necessary paperwork to join Trillium’s network, you will be able to continue seeing them. Trillium plans to maintain continuity of care for members, including the services they receive.
