What’s New: Blue Cross and Blue Shield of Texas (BCBSTX) will be updating its lists of procedure codes requiring prior authorization by AIM Specialty Health® (AIM), for some commercial members. These changes reflect new, replaced or removed codes due to updates from Utilization Management (UM) or the American Medical Association (AMA).

More Information: Refer to the Utilization Management section of our provider website for revised lists under the Prior Authorization Lists for Fully Insured and Administrative Services Only (ASO) Plans.

Changes are:

  • May 21, 2021 – Removal of Pain Management codes previously reviewed by AIM (UM change)

Check Eligibility and Benefits: To identify if a service requires prior authorization for our members, check eligibility and benefits through Availity® Learn more about third-party links or your preferred vendor.

Avoid post-service medical necessity reviews and delays in claim processing by obtaining prior authorization before rendering services. If prior authorization is required, services performed without prior authorization or that do not meet medical necessity criteria may be denied for payment and the rendering provider may not seek reimbursement from the member.
