The rendering provider must obtain prior authorization for services outlined in this notification, except for emergency care or urgent services. PCP referrals are not required if the specialty provider selected is in network.


Services performed without prior authorization and that do not meet medical necessity criteria may be denied for payment and the rendering provider may not seek reimbursement from the member.

BCBSOK and eviCore will be providing additional information, including training opportunities, in the coming months. Please continue to visit the bcbsok.com/provider site and the BCBSOK Blue Review Newsletter for updates.


Please note that the fact that a service has been preauthorized/pre-certified 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.

** Prior authorization determines whether the proposed service or treatment meets the definition of medical necessity under the applicable benefit plan. Prior authorization of a service is not a guarantee of payment of benefits. Payment of benefits is subject to several factors, including, but not limited to, eligibility at the time of service, payment of premiums/contributions, amounts allowable for services, supporting medical documentation, and other terms, conditions, limitations, and exclusions set forth in the member’s policy certificate and/or benefits booklet and or summary plan description. Regardless of any preauthorization or benefit determination, the final decision regarding any treatment or service is between the patient and the health care provider.
