Trillium partners with practitioners and provider agencies to build community well-being through the delivery of person-centered services and supports. This is accomplished by Trillium and the provider entering into a contractual agreement for the provision of services. The two main types of contract agreements include the Procurement Contract and the Out-of-Network Single Case Agreement.

Trillium maintains a closed network for behavioral health and I/DD services. To request to join the Trillium network for these services, please visit our Provider Network Participation Opportunities webpage for current network openings OR email NetworkServicesSupport@TrilliumNC.org.

As of May 1, 2022, providers will no longer submit credentialing applications directly to Trillium. Trillium will accept NC Tracks credentialing as documented in the NC Tracks Provider Eligibility File and/or the NC Tracks Operations Portal. The North Carolina Department of Health and Human Services (the Department), through NCTracks, will continue to collect information and verify credentials for all providers currently enrolled or seeking to enroll in North Carolina’s Medicaid and/or Health Choice programs or as a State-funded service provider.

What Providers Need to Know

  1. In-Network fully contracted Providers should not use the Out of Network Request Process or submit the Out of Network Request Form. In-Network Providers should contact Network Development via email at NetworkServicesSupport@TrilliumNC.org or at 1-855-250-1539 when a service need for a specific member/recipient is identified.
  2. The member meeting Medical Necessity does not guarantee a provider will receive an Out of Network Agreement, authorization, or reimbursement. To ensure a provider does not encounter delays or issues, they must:
    1. Be set up correctly in NCTracks to prevent encounter denials. This includes making sure their rendering and billing affiliations are correct, they have the required taxonomies to cover the service requested, the service address listed as 003 or higher, and their Medicaid Benefit Plan is current;
    2. Have the appropriate facility license, accreditation, certification, and licensed staff to deliver the service as defined in the Clinical Coverage Policy; and
    3. Confirm that the member has Medicaid, is covered by Trillium, and meets the requirements outlined in the service definition regarding age and diagnosis.
  3. Utilization Management makes a determination for Medical Necessity based on the service code(s) and documentation submitted to them. If the Out of Network Request form contains additional codes, they will not be included in the Agreement. Provider should ensure that all of the anticipated services are being submitted to UM when establishing Medical Necessity.
  4. NC Tracks is the statewide multi-payer Medicaid Management Information System used by the N.C. Department of Health and Human Services (NC DHHS). All providers delivering services to members must enroll with NC Tracks. Additionally, all providers must have applicable licenses, accreditations, and registrations required for its facilities and staff while providing services to Trillium members.
