This page provides a summary of pre-service requirements and recommendations for Blue Cross and Blue Shield of Oklahoma (BCBSOK) providers. Call the number on the back of the member's ID card if you have any questions.
Eligibility and Benefits Reminder: An eligibility and benefits inquiry should be completed first to confirm membership, verify coverage and determine whether or not pre-certification (also known as pre-notification or preauthorization) is required. This includes prior authorization for high-tech imaging services.
What is preauthorization?
Preauthorization is the determination of the medical necessity and appropriateness of treatment as a required part of the Utilization Management process for certain covered services. Failure to obtain these proper permissions may affect claim payment, subject to the terms and conditions of a Coverage Plan. A Preauthorization is not a guarantee of benefits or payment.
Services which may require preauthorization
- Inpatient admissions (scheduled and/or non emergent), certain outpatient services, emergent admissions/obstetric, requests for extensions and Plan65 Members when their Medicare Part A benefits have been exhausted.
- Other services may also require preauthorization. Please refer to the number on the back of the member's ID card to obtain Preauthorization requirements.

Who is responsible for preauthorization?

Preauthorization for an Extension of Approved Days

Preauthorization vs benefits
Preauthorization is a determination of medical necessity for the delivery of services. An approved authorization of services by the Preauthorization process is not a guarantee of benefits. It is the responsibility of the rendering BCBSOK participating provider to verify eligibility and benefits prior to the date of service, to the extent practical. Benefits can be requested by contacting the customer service number listed on the back of the member's ID card.
Failure to obtain preauthorization may result in a financial penalty. For more information, please refer to your BCBSOK participating provider agreement.
iEXCHANGE supports direct submissions and provides online approval of benefits for inpatient admissions, referrals and select outpatient services. iEXCHANGE is accessible to network physicians, professional providers and facilities within Oklahoma 24-hours-a-day, seven-days-a-week.
A Predetermination is a voluntary request that a provider may submit to BCBSOK to determine in advance whether a specific service is Medically Necessary. A Predetermination is not a guarantee of Benefits or a substitute for the Preauthorization process, when required.
Examples of services for which the provider may request a Predetermination include:
- outpatient services
- durable medical equipment
- surgeries that might be considered cosmetic
- possible experimental and investigational procedures/treatments
For your convenience, we have included a link to a list for codes where Predetermination may be available and is recommended *. Please refer to BCBSOK's medical policies for medical necessity criteria.
The following provides links to specific lists* that include codes unlikely to be considered medically necessary and codes that would not be considered for Predetermination:
- Codes that BCBSOK has determined to be not medically necessary per BCBSOK's medical policies . Please refer to BCBSOK's medical policies for more information.
- Codes that BCBSOK has determined to be Experimental/Investigational/Unproven (EIU) per BCBSOK's medical policies . Please refer to BCBSOK's medical policies for more information.
- Codes that are commonly not a benefit for BCBSOK Members . Predetermination is not available for services that are not a benefit or are subject to a benefit exclusion.
Steps for Requesting a Predetermination
- Always verify eligibility and Benefits first.
- To request a Predetermination, please complete the Predetermination Request form . All applicable fields are required. If any information is not provided, this may cause a delay in the Predetermination process. (Requests received without the member/patient's group number, ID number, and date of birth cannot be completed and may be returned.)
- Fax information for each patient separately, using the fax number indicated on the form.
- Always place the Predetermination Request form on top of other supporting documentation. Please include any additional comments if needed with supporting documentation.
- Do not send in duplicate requests, as this may delay the process.
- Per Medical Policy, if photos are required for review, the photos should be mailed to the address indicated on the Predetermination Request form and not faxed. Faxed photos are not legible and cannot be used to make a determination.
- Regarding major diagnostic tests, please include the patient's history, physical and any prior testing information.
* The attached lists are for reference only and are not intended to be a substitute for benefit verification or BCBSOK's medical policies.

** Preauthorization determines whether the proposed service or treatment meets the definition of medical necessity under the applicable benefit plan. Preauthorization 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.
