Update to Prior Authorization Codes for Medicaid Members, Effective Jan. 1, 2023

October 5, 2022

What’s Changing: Blue Cross and Blue Shield of Texas (BCBSTX) is changing prior authorization requirements for Medicaid members to reflect new, replaced or removed codes due to updates from Utilization Management prior authorization assessment, Current Procedural Terminology (CPT®) code changes released by the American Medical Association (AMA) or Healthcare Common Procedure Coding System (HCPCS) changes from the Centers for Medicaid & Medicare Services.

Changes effective Jan. 1, 2023 include additional and removal of codes for the following care categories to be reviewed by healthcare: 

  • Sleep drug codes to be reviewed by eviCore
  • Radiation Oncology code to be reviewed by eviCore
  • Specialty Drug codes to be reviewed by eviCore
  • Addition of prior authorization codes to be reviewed by BCBSTX
  • Removal of prior authorization codes previously reviewed by BCBSTX

Refer to the Utilization Management section of our Medicaid provider website for access to the Prior Authorization Lists and Report.

Check Eligibility and Benefits: To identify if a service requires prior authorization for our members, check eligibility and benefits through Availity® Essentials  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.
