Blue Cross and Blue Shield of Illinois (BCBSIL) is changing prior authorization requirements that may apply to some commercial non-HMO members.

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. 

Even if prior authorization isn’t required for a commercial non-HMO member, you still may want to submit a voluntary predetermination request. This step can help avoid post-service medical necessity review. Checking eligibility and benefits can’t tell you when to request predetermination, since it’s optional. But there’s a Medical Policy Reference List on our Predetermination page to help you decide.

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.

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.
