eviCore Prior Authorization Requirements

April 1, 2019

Blue Cross and Blue Shield of Texas (BCBSTX) contracts with eviCore healthcare (eviCore), an independent specialty medical benefits management company, to administer prior authorization requirements for select specialized services and products for BCBSTX members.

For a detailed list of the services that require authorization through eviCore, refer to the eviCore implementation site.

To determine which specialized clinical services require prior authorization through eviCore for your member, providers should check eligibility, benefits and prior authorization requirements through Availity® or your preferred vendor. Also, reference the Prior Authorization/Referral/Notification page on the BCBSTX provider website. Services performed without authorization may be denied for payment and you may not seek reimbursement from members.

Note: Some plans may require inpatient musculoskeletal surgery medical necessity authorization through eviCore and the provider will be required to supply the eviCore prior authorization number to BCBSTX to obtain a BCBSTX prior authorization number for the inpatient stay.

eviCore authorizations can be obtained using one of the following methods:

  • Use the eviCore healthcare web portal, which is available 24/7. After a one-time registration, you can initiate a case, check status, review guidelines, view authorizations and eligibility, and more. The web portal is the quickest, most efficient way to obtain information.
  • Call eviCore at 1-855-252-1117 toll-free between 6 a.m. – 6 p.m. CT, Monday through Friday and 9 a.m. – noon CT, Saturday, Sunday and legal holidays.

For all other services that require a referral and/or authorization through BCBSTX, continue to use iExchange®. iExchange is accessible to all physicians, professional providers and facilities. You can learn more about iExchange or set up a new account on the BCBSTX provider website.
