Contracting and Credentialing

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.

The Procurement Contract is issued to provider agencies and practitioners that have completed the Trillium credentialing process and are deemed qualified to participate in the Trillium Provider Network.  The Procurement Contract carries a lifespan up to three years and is the preferred contracting method.

Combined Medicaid and State Contract Template

An Out-of-Network Single Case Agreement (OON SCA) is an agreement between Trillium and a provider agency or practitioner that has not contracted with Trillium; however has chosen to render services to an individual enrolled with Trillium. Single Case Agreements are member specific and require prior approval from Trillium for every member served.    

NOTE: The Out-of-Network Single Case Agreement process is for provider agencies and practitioners that do not have a current contract with Trillium. Credentialed provider agencies and practitioners that have a current contract to be an In-Network Provider should contact Trillium Network Development to request additions to their contract. Network Development can be contacted using one of the following methods:  

Before Submitting an Out-Of-Network Single Case Agreement Request (OON SCA)

Before submitting an OON SCA request, a provider agency or practitioner must verify that Trillium covers the desired service(s) and confirm there is no In-Network Provider available to deliver the service(s).   

  1. For a complete list of covered services, review the Trillium Benefit Plan
  2. To confirm In-Network Provider availability, access the Trillium Provider Directory or contact the assigned Care Manager. If there is no Care Manager assigned, contact Trillium at 1-877-685-2415 for assistance in selecting an In-Network Provider.   

If a provider agency or practitioner still requires an OON SCA, the following steps should be completed in the order detailed below. Any deviation will cause delays in the overall process.  

STEP 1: Confirm NCTracks Enrollment

Every provider agency, practitioner, and supplemental delivering a service to a Medicaid eligible member or State-funded recipient, must be enrolled and active in NCTracks. Trillium will conduct a review of NCTracks enrollment prior to initiating the OON SCA process. Before submitting an OON SCA request, provider agencies and practitioners should confirm the following:  

  1. NCTracks enrollment;
  2. Provider Status is “01-Active”;
  3. Taxonomy Classification will adjudicate the service(s) requested; 
  4. The service address is found under Service Location as 003 or above (if applicable); and 
  5. The correct rendering provider affiliations are present (if applicable).

To review your information visit the NCTracks website .  

STEP 2: NCTracks Verification and Establish Medical Necessity

During Step 2, the following will occur in this order: 

  1. The provider agency or practitioner will submit the required information outlined below. 
  2. Trillium will verify NCTracks enrollment.
  3. Based on NCTracks enrollment findings: 
    1. No Issues found – Utilization Management (UM) will complete the Medical Necessity (MN) determination, notify the provider agency or practitioner of the decision, and provide instructions for submitting the OON Request form (when applicable).
    2. Issues found – The OON SCA process will stop and Trillium will notify the provider agency or practitioner of NCTracks enrollment findings.  

To initiate Step 2, the provider agency or practitioner must contact Utilization Management and provide the following information:

Required for NCTracks Verification:

  • Provider Name (as listed on a W-9)
  • Provider TaxID
  • Provider NPI
  • Provider Taxonomy

STEP 3: Submit the OON Request Form & Documents

Unsolicited OON SCA request forms will be returned as Unable to Process with instructions to contact Utilization Management. Provider agencies and practitioners are encouraged to review their information thoroughly. Incomplete request forms and missing documentation will cause delays in this process.

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.
