FOR CLINICAL LABORATORY SERVICES THAT CAN BE PERFORMED IN NETWORK
Participating practitioners are encouraged to refer their Horizon BCBSNJ patients to preferred national clinical laboratories whenever possible.

  • Participating practitioners are required to refer their Horizon BCBSNJ patients enrolled in plans that do not include out-of-network benefits to participating clinical laboratories.

  • Participating practitioners are expected to refer their Horizon BCBSNJ patients enrolled in plans that include out-of-network benefits (or forward their testing samples) to participating clinical laboratories, whenever possible.

    Participating practitioners must comply with the guidelines of our Out of Network Referral Policy² When referring such a patient or forwarding his/her sample to a non-participating clinical laboratory.

Participating practitioners are strongly encouraged to visit the websites of our participating clinical labs to review their test menus/directories to understand which laboratory services are available.

  • Visit LabCorp.com and click Test Menu to review their complete test menu.
  • Visit QuestDiagnostics.com, select the For Physicians & Hospitals tab, and click Test Directory to review their complete test menu.
  • Visit BioReference.com, select Physicians, then click Test Directory to review their complete test menu.

FOR CLINICAL LABORATORY SERVICES THAT CANNOT BE PERFORMED IN NETWORK
There may be certain clinical laboratory services that are not performed by LabCorp, Quest Diagnostics, BioReference Laboratories or other participating clinical laboratory services providers.

  • Please call 1-800-664-2583 to obtain Prior Authorization before referring a patient or forwarding a sample to a non-participating clinical laboratory for services that cannot be provided by LabCorp, Quest Diagnostics, BioReference or another clinical laboratory participating with your patient’s plan.
  • If you do not obtain Prior Authorization, non-participating clinical laboratory claims will NOT be considered at your patients’ in-network level of benefits:
    • Claims will be processed at the out-of-network level of benefits for your patients enrolled in plans that include OON benefits (as such, higher member cost sharing may apply to those OON claims)
    • Claims will be denied for your patients enrolled in plans with no OON benefits.

¹ Pathology services provided in a hospital setting to members enrolled in Horizon BCBSNJ managed care plans by a practice that participates in the Horizon Managed Care Network are allowed as an exception to the above-described LabCorp/Quest Diagnostics network use requirements.
