Summary
Blue Cross Blue Shield of Illinois is implementing multiple prior authorization changes across different dates, affecting commercial non-HMO members, Medicare Advantage members, and Blue Cross Community Health Plans members. The changes involve adding and removing various procedure codes from prior authorization requirements, with different utilization management vendors (BCBSIL, EviCore, and Carelon) handling different services.
Action Required
By April 1, 2026: Billing team must update prior authorization workflows for BCBS Illinois members. Check eligibility and benefits through Availity Essentials before rendering services to confirm current prior auth requirements and correct utilization management vendors (BCBSIL, EviCore, or Carelon). Update staff training on the multiple effective dates: April 1, 2026 for Medicare Advantage and BCCHP changes, July 1, 2026 for additional commercial and BCCHP changes. Services performed without required prior authorization may be denied and providers cannot bill members directly.
