Always check eligibility and benefits first through Availity® Essentials or your preferred vendor prior to rendering services. This step will confirm prior authorization requirements and utilization management vendors, if applicable.
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 coverage contract or guide. If you have any questions, call the number on the member's ID card.
Services performed without required 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.
