Trillium's Provider Network

We are proud to work together with a network of incredible health care providers to offer the right, individualized care for the people we serve. Our collective community-based approach focuses on meeting people’s unique needs. Trillium recognizes that our success in managing these services depends upon the providers in our network.

We will not compromise the quality of services for serious Mental Health (MH), substance Use (SU), and Intellectual/Developmental Disabilities (I/DD).

Providers Manual

Trillium's Provider Manual includes important information including the following:

  • How to file claims
  • Member Rights, including filing appeals and grievances
  • Provider Responsibilities

Providers have the right to appeal certain actions that Trillium takes against them. Trillium outlines our Provider appeals processes in the Provider Manual. Trillium provides written notice of a Provider's appeal rights with the notice of decision giving rise to the Provider's right to appeal. Trillium allows Providers to submit a written appeal request through Trillium's online Provider portal, Provider Direct, or by mailing a copy of the request, via certified mail, to Trillium (201 West 1st. St., Greenville, NC 27858).

For more information on provider appeals, please refer to the Provider Manual, or contact Trillium's Appeals Coordinator (1-855-250-1539).

Please note requirements covered for the Trillium Tailored Plan are not effective until Tailored Plan is launched.
