Renewal Triggers: When to Start
Blue Shield of California typically approves Filspari in 6-12 month intervals for IgA nephropathy. Start your renewal process early to avoid treatment interruptions.
Key Renewal Windows
- 45 days before expiration: Ideal start time for complex cases
- 30 days before expiration: Standard renewal timeline
- 15 days before expiration: Minimum window (request expedited review)

Tip: Check your approval letter for the exact expiration date. Blue Shield often includes renewal requirements in the initial authorization.
Early Warning Signs
Start renewal preparation if you notice:
- Specialty pharmacy mentions upcoming expiration
- Insurance portal shows "authorization ending soon"
- Clinic receives Blue Shield renewal reminder
- Annual formulary changes affect Filspari tier placement
Evidence Update Requirements
California's Blue Shield Filspari policy requires documented clinical benefit and safety monitoring for continued coverage.
Clinical Response Documentation
Proteinuria Improvement
- Current UPCR compared to baseline (aim for ≥30-50% reduction)
- 24-hour urine protein if UPCR unavailable
- Trend analysis showing stabilization or improvement
Kidney Function Stability
- Current eGFR vs. baseline
- Annual eGFR loss ≤1-2 mL/min/1.73 m²/year preferred
- Serum creatinine trends over treatment period
Safety Monitoring (REMS Requirements)
Quarterly Liver Function Tests
- ALT, AST, total bilirubin, alkaline phosphatase
- Must be within 90 days of renewal request
- No values >3x upper limit of normal without explanation
Additional Safety Labs
- Blood pressure readings (target <140/90 mmHg)
- Serum potassium levels
- Pregnancy test if applicable (sparsentan is contraindicated in pregnancy)
Note: The FDA REMS program requires quarterly LFTs throughout treatment. Missing labs are a common renewal denial reason.

FAQ
How long does Blue Shield CA Filspari renewal take? Standard renewals take 15-30 business days. Expedited reviews can be completed in 3-5 days for urgent cases.
What if my UPCR hasn't improved much? Document eGFR stability and emphasize that Filspari prevents progression. Include nephrologist letter explaining that stabilization represents clinical benefit in IgA nephropathy.
Can I switch from Blue Shield to another plan mid-treatment? Yes, but new plans may have different coverage criteria. Request continuity of care provisions during plan transitions.
What happens if I miss quarterly liver tests? Blue Shield may deny renewal until current LFTs are obtained. The REMS program requires quarterly monitoring throughout treatment.
Does step therapy apply to Filspari renewals? Current Blue Shield policies don't specify step therapy for Filspari, but verify with your specific plan as policies can change mid-year.
How do I know if my renewal was approved? Check the Blue Shield member portal, contact your specialty pharmacy, or call the number on your insurance card for authorization status.
