How to Request Prior Authorization or Recommended Clinical Review (Predetermination)

The following outlines the process for providers to submit prior authorization requests.

Services which may require Prior Authorization

  • Inpatient admissions (scheduled and/or nonemergent), certain outpatient services, emergent admissions/obstetric (request authorization within two (2) business days of the admission), requests for extensions and Plan65 Members when their Medicare Part A benefits have been exhausted.
  • Other services may also require preauthorization. Always check eligibility and benefits first, via the Availity® Provider Portal  or your preferred vendor, prior to rendering care and services.

For additional information, refer the Electronic Provider Access (EPA) FAQs  located in the right navigation menu.

Prior Authorization for an Extension of Approved Days
Should additional days of treatment be deemed necessary, it is the responsibility of the facility, treating physician or ancillary provider to request an extension in accordance with the BCBSOK participating provider agreement.

Prior Authorization vs benefits
Prior Authorization is a determination of medical necessity for the delivery of services. An approved authorization of services by the Prior Authorization 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. Benefits can be verified via the Availity® Provider Portal or your preferred vendor; or by contacting the customer service number listed on the back of the member's ID card.

Prior Authorization Penalty
Failure to obtain preauthorization may result in a financial penalty. For more information, please refer to your BCBSOK participating provider agreement.
