Renewal Triggers: When to Start the Process

Kalydeco (ivacaftor) renewals with Blue Cross Blue Shield of California typically occur every 6-12 months, depending on your specific plan and initial approval duration. Blue Shield treats Kalydeco as a specialty drug requiring ongoing prior authorization review.

Signs You Should Start Early

  • Authorization expires in 4-6 weeks: Don't wait until the last minute
  • Recent hospitalizations or exacerbations: May require additional documentation
  • Lab abnormalities: Elevated liver enzymes need explanation and management plan
  • Plan changes: New employer coverage or Medicare transition affects approval criteria
  • Pharmacy alerts: Accredo or your specialty pharmacy flags upcoming expiration
Tip: Set a calendar reminder 6 weeks before your authorization expires. This gives time for gathering documents and addressing any complications.

Critical Timing Windows

Most CF centers recommend starting renewal preparation 30 days before expiration to account for:

  • Scheduling required lab work and clinic visits
  • Obtaining updated pulmonary function tests

FAQ: Common Renewal Questions

How long does Blue Cross Blue Shield prior authorization renewal take in California? Standard renewals typically take 5-15 calendar days. Expedited reviews for urgent situations are completed within 72 hours.

What if my FEV₁ has declined since starting Kalydeco? Document any factors contributing to decline (infections, adherence issues, natural disease progression). Emphasize stabilization compared to expected trajectory without treatment.

Can I request an expedited renewal? Yes, if treatment interruption would pose significant health risk. Your CF specialist must provide clinical justification for urgency.

What happens if Blue Shield denies my renewal? File an internal appeal immediately, then pursue California's Independent Medical Review (IMR) if still denied. The state process is free and has favorable overturn rates.

Does step therapy apply to Kalydeco renewals? Generally no, if you're already stable on Kalydeco. California law provides step therapy exceptions for patients who have failed alternatives or are stable on current therapy.

How often do I need new genetic testing? Your CFTR genotype doesn't change, so initial genetic testing typically suffices unless the plan specifically requests updated documentation.

What if I'm transitioning from Kalydeco to Trikafta? This requires a new prior authorization for Trikafta rather than a Kalydeco renewal. Work with your CF center to coordinate the transition and ensure no treatment gap.

Can coverage gaps affect my long-term approval? Document any gaps carefully. Brief interruptions due to administrative delays typically don't affect future approvals if properly documented.
