Referrals and Pre-Authorizations
A referral is when your primary care manager or provider sends you to another provider for care that they don’t provide.
An authorization is when TriWest Healthcare Alliance approves your care before you go to your appointment. When referred, your provider will get you a referral and pre-authorization (if required) at the same time. You’ll receive an authorization letter from TriWest letting you know what steps to take next.
