Please note that the fact that a service has been preauthorized/pre-notified, that a guideline is available for any given treatment or that a service or treatment has been predetermined for benefits, 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 applicable on the date services were rendered. If you have any questions, call the number on the member’s ID card.
