Work With Your Doctor to Get Filspari (Sparsentan) Approved by Cigna in Illinois: Forms, Appeals, and Timeline

Answer Box: Getting Filspari Approved by Cigna in Illinois

To get Filspari (sparsentan) covered by Cigna in Illinois, you need: (1) biopsy-proven IgA nephropathy with proteinuria ≥1.0 g/day and eGFR ≥30 mL/min, (2) documented failure/intolerance of maximized ACE inhibitor or ARB therapy for ≥90 days, and (3) REMS enrollment with quarterly liver function monitoring. First step today: Schedule a visit with your nephrologist to review your kidney biopsy results, recent labs (UPCR, eGFR), and prior treatment history. Illinois residents have strong appeal rights with 180-day internal appeal deadlines and binding external review through the Illinois Department of Insurance if initial denials occur.

Set Your Goal: Understanding Cigna's Requirements

Filspari (sparsentan) is a first-in-class medication for IgA nephropathy that requires prior authorization from Cigna. Your partnership with your nephrologist is crucial because Cigna's coverage policy requires specific clinical documentation that only your doctor can provide.

Coverage Requirements at a Glance

Requirement What It Means Where to Find It
Biopsy-proven IgA nephropathy Kidney tissue diagnosis showing IgA deposits Nephrology records, pathology report
Proteinuria ≥1.0 g/day Protein spillage indicating kidney damage UPCR lab results (≥1000 mg/g)
eGFR ≥30 mL/min/1.73m² Sufficient kidney function for medication Recent comprehensive metabolic panel
Prior ACE/ARB trial Failed or intolerant to standard therapy ≥90 days Medication history, clinic notes
Nephrologist prescription Specialist management required Referral or established care
REMS enrollment Safety monitoring program FilspariREMS.com

Your goal is to work with your doctor to demonstrate that Filspari meets medical necessity criteria and that you've exhausted standard treatments.

Visit Preparation: What to Document

Before your appointment, gather information that tells your kidney disease story clearly. Your nephrologist needs this timeline to write a compelling prior authorization request.

Symptom and Treatment Timeline

  • When was your IgA nephropathy diagnosed? Include the date of your kidney biopsy and key findings (MEST-C score if available).
  • What medications have you tried? List ACE inhibitors (lisinopril, enalapril) or ARBs (losartan, valsartan) with dates, doses, and reasons for stopping.
  • How has your kidney function changed? Bring lab results showing UPCR and eGFR trends over the past 6-12 months.
  • What side effects occurred? Document specific problems like persistent cough (ACE inhibitors), dizziness, or kidney function decline.

Functional Impact Notes

Write down how proteinuria and declining kidney function affect your daily life. This helps your doctor understand the urgency of switching to Filspari and can strengthen appeals if needed.

Tip: Keep a simple log for 1-2 weeks before your visit noting energy levels, swelling, and any symptoms. This real-world data supports your case for advanced therapy.

Building Your Evidence Kit

Your nephrologist needs specific documentation to submit a successful prior authorization. Help them by organizing your medical history and understanding what Cigna requires.

Essential Lab Results

  • Recent UPCR or 24-hour urine protein (within 30-90 days)
  • Comprehensive metabolic panel showing eGFR
  • Liver function tests (ALT, AST, bilirubin) for REMS baseline
  • Blood pressure readings demonstrating control on current therapy

Medical Records to Request

  • Kidney biopsy report with pathologist interpretation
  • Nephrology consultation notes from initial diagnosis
  • Medication trial documentation showing ACE/ARB attempts
  • Prior authorization denials if you've tried other medications

Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters alongside plan policies and clinical notes. Their platform helps identify the specific denial basis and drafts point-by-point rebuttals aligned to each plan's requirements.

Medical Necessity Letter Structure

Your nephrologist's letter of medical necessity is the cornerstone of your prior authorization. Here's what it should include based on current clinical guidelines and payer requirements:

Key Components

Patient Identification & Diagnosis

  • Full name, date of birth, insurance ID
  • ICD-10 code N02.8 (recurrent and persistent hematuria with other morphologic changes)
  • Biopsy date and findings confirming primary IgA nephropathy

Clinical Rationale

  • Current UPCR demonstrating ≥1.0 g/day proteinuria despite maximized supportive care
  • eGFR ≥30 mL/min/1.73m² confirming adequate kidney function
  • Blood pressure control status on current regimen

Prior Treatment History

  • Specific ACE inhibitor or ARB tried (medication name, dose, duration)
  • Reason for discontinuation (ineffective, side effects, contraindication)
  • Documentation of ≥90-day trial at maximally tolerated dose

Treatment Plan

  • Filspari 400 mg once daily dosing
  • REMS enrollment completion
  • Monitoring plan: quarterly liver function tests, monthly UPCR initially

Supporting Evidence

Your doctor should reference the PROTECT trial data showing Filspari's superior proteinuria reduction compared to standard therapy and cite 2025 KDIGO guidelines supporting its use in high-risk IgA nephropathy.

Peer-to-Peer Review Support

If Cigna initially denies your prior authorization, your nephrologist can request a peer-to-peer review by calling 800-882-4462. This allows direct discussion with a Cigna medical director before formal appeals.

How to Support Your Doctor

Offer Scheduling Flexibility

  • Provide your doctor's office with several time windows when you're available for three-way calls
  • Peer-to-peer reviews often happen within 24-72 hours of request

Prepare a Concise Case Summary

  • One-page timeline of your diagnosis, treatments tried, and current status
  • Recent lab values and functional impact notes
  • This helps your doctor present your case clearly and confidently

Key Talking Points for Your Doctor

  • Emphasize that you meet FDA-approved indications exactly
  • Highlight failed ACE/ARB therapy with specific dates and outcomes
  • Reference your REMS enrollment readiness and monitoring compliance
  • Stress progression risk without effective proteinuria reduction
From Our Advocates: We've seen peer-to-peer reviews succeed when nephrologists emphasize patient-specific factors like rapid proteinuria progression despite maximized supportive care. Having organized lab trends and clear documentation of prior therapy failures makes these conversations much more effective than general clinical discussions.

After Your Visit: Next Steps

What to Save and Document

  • Prior authorization confirmation number if submitted
  • Clinic visit summary with diagnosis codes and treatment plan
  • Copy of medical necessity letter for your records
