What Affects Nucala Approval Timing

Several factors determine how quickly Blue Cross Blue Shield of Texas processes your Nucala prior authorization:

Benefit Type & Plan Structure

  • Commercial plans: Standard 3-15 business days
  • Medicare Advantage: May require additional CMS compliance checks
  • Self-funded employer plans: Follow ERISA rules, not Texas timelines

Clinical Complexity

Your approval speed depends on meeting specific criteria:

  • Eosinophil count documentation: ≥150 cells/μL required
  • Step therapy status: Must show benralizumab or dupilumab failure/contraindication
  • Specialist involvement: Pulmonologist, allergist, or immunologist prescription required

Documentation Completeness

Complete submissions process faster. Missing items trigger information requests that add 3-7 days.

Note: Starting April 2025, BCBS Texas will review whether Nucala requires healthcare facility administration or can be self-administered, potentially affecting processing time.
