Services that are medically necessary and a covered benefit under the eligible member’s health plan are usually paid automatically, but certain services require prior authorization before they can be provided. These services, especially those that may result in expensive procedures, undergo the prior authorization process to ensure those services will be covered.

We will decide within 15 days of receipt of your request for prior authorization. Read more about “medical necessity,” and details about services which require prior authorization in our Provider Handbook. Health Care Services is available to assist you with all prior authorization requests and advance notification requirements.
