Important Reminders
Always check eligibility and benefits first through Availity® Essentials or your preferred vendor portal, prior to rendering services. This step will confirm prior authorization requirements and utilization management vendors, if applicable.

If prior authorization is required, services performed without prior authorization or that do not meet medical necessity criteria may be denied for payment and the rendering provider may not seek reimbursement from the member. Avoid post-service medical necessity reviews and delays in claim processing by obtaining prior authorization before rendering services.


Checking eligibility and/or benefit information and/or obtaining prior authorization is not a guarantee of payment. Benefits will be determined once a claim is received and will be based upon, among other things, the member’s eligibility and the terms of the member’s certificate of coverage, including, but not limited to, exclusions and limitations applicable on the date services were rendered. If you have any questions, call the number on the member's ID card.
