Referrals, Authorizations, Out-of-Network

  • You may need our okay ahead of time (prior authorization) for certain services, procedures, and out-of-network providers before you receive care.
  • You will receive written notice of our approval or denial. You may check the status of your request at

If you are unsure if a service, test, or procedure requires prior authorization or a referral, call (844) 644-3455 before the appointment or visit

Emergency and Urgent Care

If you need emergency or urgent care out-of-network, seek care at the nearest medical facility. Contact your primary care provider if you need help determining the appropriate level of care. Follow-up care must be received from an in-network provider unless approved by Quartz.

Mental, Behavioral Health and Substance Abuse

Being healthy isn’t just about your body – it’s about your mind, too. To access mental, behavioral health, or substance abuse services, call Behavioral Health Care Management at (800) 683-2300. We’ll connect you to the support you need.

24-Hour Nurseline

Contact your primary care provider for after-hours or out-of-area care instructions.

Virtual Visits

Take advantage of technology to access 24/7 on-demand care for non-emergency needs. Virtual visits connect you to a health care provider via your smartphone, tablet, or computer webcam. Depending on the issue, the provider can provide a diagnosis, suggest follow-up care, and prescribe medication when appropriate.
