Renewal Triggers: When to Start the Process

Your Hemlibra renewal process should begin 60-90 days before your current authorization expires. Blue Cross Blue Shield of Michigan typically grants initial authorizations for 6 months, with renewals approved for up to 12 months.

Signs You Should Start Early

  • Authorization expires within 90 days: Check your approval letter or call BCBS member services at the number on your insurance card
  • Bleeding pattern changes: New breakthrough bleeds or increased frequency may require additional documentation
  • Dosing adjustments: Any changes to your weekly, biweekly, or monthly dosing schedule
  • Insurance plan changes: Switching between BCBS plans or employer groups
  • Specialist changes: New hematologist or hemophilia treatment center
Tip: Set a calendar reminder 90 days before your authorization expires. Most denials for renewals stem from incomplete documentation or late submissions.

Evidence Update: What BCBS Michigan Needs to See

BCBS Michigan's renewal criteria focus on documented clinical benefit and continued medical necessity. Your hematologist must provide evidence that Hemlibra is working effectively.

Required Clinical Evidence

Bleeding Episode Documentation:

  • Pre-treatment bleeding frequency (baseline before starting Hemlibra)
  • Current bleeding frequency while on therapy
  • Quantifiable reduction: BCBS looks for measurable improvement, typically a 50% or greater reduction in bleeding episodes

Laboratory Monitoring:

  • Confirmation that standard clotting tests (aPTT, Bethesda assays) are not being used for monitoring
  • If inhibitor testing was needed, documentation that bovine chromogenic FVIII inhibitor assays were used
  • No evidence of anti-emicizumab antibodies affecting efficacy

Treatment Response Indicators:

  • Reduced need for breakthrough factor VIII treatments
  • Improved quality of life measures (if documented)
  • Absence of thrombotic complications
  • Continued adherence to prescribed dosing schedule

Specialist Oversight Requirements

BCBS Michigan requires that Hemlibra be prescribed by a hematologist or hemophilia treatment center specialist. Your renewal must include:

  • Current specialist evaluation notes
  • Confirmation of ongoing specialist oversight
  • Treatment plan for the upcoming authorization period

Renewal Packet: Must-Include Documentation

Your complete renewal submission should include these essential documents:

Core Documentation Checklist

  • Completed prior authorization form (use BCBS Michigan's current PA form - verify with provider services)
  • Specialist letter from hematologist detailing clinical benefit
  • Bleeding episode log comparing pre-treatment to current frequency
  • Current diagnosis confirmation (Hemophilia A with ICD-10 code)
  • Weight-based dosing justification (if applicable)
  • Previous authorization approval letter (for reference)

Medical Necessity Letter Structure

Your hematologist's letter should address these key points:

  1. Patient diagnosis: Congenital Hemophilia A with or without FVIII inhibitors
  2. Treatment history: Previous factor VIII prophylaxis attempts and outcomes
  3. Clinical response: Specific reduction in bleeding episodes since starting Hemlibra
  4. Continued need: Why ongoing prophylaxis is medically necessary
  5. Single-agent use: Confirmation that Hemlibra is not being used with immune tolerance induction (ITI)
  6. Monitoring plan: How treatment response will be assessed going forward

FAQ: Common Renewal Questions

Q: How long does BCBS Michigan take to approve Hemlibra renewals? A: Standard renewals are typically approved within 5-7 business days for complete submissions. Urgent requests may be processed within 24-48 hours with clinical justification.

Q: What if my bleeding episodes have increased while on Hemlibra? A: Document any breakthrough bleeds and discuss with your hematologist. Increased bleeding may indicate need for dosing adjustment, anti-drug antibodies, or additional evaluation. This doesn't automatically disqualify you for renewal but requires thorough documentation.

Q: Can I get expedited renewal if my authorization expires soon? A: Yes, if continuing therapy is medically urgent. Your hematologist must provide documentation that interruption would pose immediate health risks. Submit expedited requests at least 5-7 days before expiration.

Q: What happens with the September 2025 benefit change? A: Hemlibra coverage moves from medical to pharmacy benefit for commercial BCBS Michigan members. Existing authorizations remain valid through August 31, 2025, with automatic transition to pharmacy benefit afterward.

Q: Do I need to try other treatments again for renewal? A: Generally no. If you've already demonstrated clinical benefit with Hemlibra, BCBS typically doesn't require retrial of previously failed therapies for renewal. However, document why alternatives remain inappropriate.

Q: What if my hemophilia treatment center changes? A: Notify BCBS of the specialist change and ensure your new HTC has access to your complete treatment history. The new specialist may need to provide additional documentation supporting continued Hemlibra therapy.
