Work With Your Doctor to Get Filspari (sparsentan) Approved by Cigna in California: Complete Coverage Guide

Answer Box: Getting Filspari (sparsentan) Covered by Cigna in California

Cigna requires prior authorization for Filspari (sparsentan) in IgA nephropathy, mandating biopsy-confirmed diagnosis, nephrologist prescription, and quarterly liver function tests through their REMS program. Your fastest path to approval: Schedule a visit with your nephrologist to document proteinuria ≥0.8 g/g creatinine, prior ACE inhibitor/ARB failure, and eGFR ≥30 mL/min/1.73m². First step today: Call your nephrologist's office to request your kidney biopsy report and recent lab values—you'll need these for the medical necessity letter. If denied, California's Independent Medical Review (IMR) provides free external review with high success rates for rare disease treatments.

Set Your Goal: Understanding Cigna's Requirements

Your partnership with your nephrologist starts with understanding exactly what Cigna needs to approve Filspari (sparsentan). According to Cigna's coverage policy, approval requires meeting specific clinical criteria—and your doctor will need your help gathering the right documentation.

Coverage Requirements at a Glance

Requirement What It Means Your Role
Biopsy-confirmed IgA nephropathy Kidney tissue diagnosis required Request copy of biopsy report
Proteinuria ≥0.8 g/g creatinine Protein spillage in urine Track recent urine tests
Prior ACE/ARB therapy ≥12 weeks Failed standard blood pressure meds Document medication history
eGFR ≥30 mL/min/1.73m² Adequate kidney function Know your recent lab values
Nephrologist prescription Specialist involvement required Ensure referral is active
REMS enrollment Safety monitoring program Agree to quarterly liver tests

Your goal: Help your nephrologist demonstrate that you meet every requirement with clear documentation. Missing even one piece can trigger an automatic denial.

Visit Preparation: Gathering Your Medical History

Before your appointment, create a comprehensive timeline that your doctor can reference when writing your medical necessity letter.

Symptom and Treatment Timeline

Prepare to discuss:

  • When symptoms started: Date of first blood or protein in urine
  • Diagnosis journey: When you had your kidney biopsy and results
  • Current symptoms: Swelling, fatigue, changes in urination
  • Blood pressure medications tried: Names, doses, how long you took them, and why you stopped or changed
  • Side effects experienced: Document any adverse reactions to previous treatments
Tip: Create a simple timeline document before your visit. List dates, medications, and outcomes. Your doctor will appreciate having this organized information.

Functional Impact Notes

Your doctor needs to understand how IgA nephropathy affects your daily life. Be prepared to describe:

  • Work or school limitations due to fatigue or frequent medical appointments
  • Physical activities you've had to modify or stop
  • Sleep quality and energy levels
  • Concerns about kidney function and future treatment needs

This functional impact helps justify why Filspari is medically necessary beyond just lab values.

Building Your Evidence Kit

Your nephrologist will need specific documentation to build a compelling case. Here's what to gather:

Essential Documents

Request from your doctor's office:

  1. Kidney biopsy report with pathology findings
  2. Recent lab results (last 3-6 months):
    • Urine protein-to-creatinine ratio (UPCR)
    • Estimated glomerular filtration rate (eGFR)
    • Liver function tests (ALT, AST)
  3. Blood pressure medication history with dates and responses
  4. Progress notes from nephrology visits

Clinical Guidelines Support

Your doctor will reference current treatment guidelines, particularly the 2025 KDIGO IgA Nephropathy Guidelines, which support Filspari for patients with persistent proteinuria despite optimal supportive care.

Key evidence points your doctor will emphasize:

  • Disease progression risk: Proteinuria >0.8 g/g indicates high risk for kidney failure
  • Treatment failure: Inadequate response to ACE inhibitors or ARBs after adequate trial
  • Guideline alignment: Filspari fits current nephrology society recommendations

Medical Necessity Letter Structure

Understanding how your doctor will structure the medical necessity letter helps you provide the right information during your visit.

Essential Components

Your doctor will include:

  1. Patient demographics and insurance information
  2. Diagnosis confirmation: "Primary IgA nephropathy confirmed by kidney biopsy on [date]"
  3. Clinical rationale: Why Filspari is necessary based on your specific situation
  4. Risk documentation: Evidence you're at risk for kidney disease progression
  5. Treatment history: What you've tried and why it didn't work adequately
  6. Supporting references: Guidelines and studies supporting Filspari use
Clinician Corner: Medical Necessity Checklist✓ Biopsy-confirmed IgA nephropathy with date✓ Current proteinuria level and eGFR✓ Documentation of ACE/ARB therapy ≥12 weeks✓ Evidence of disease progression risk✓ Reference to KDIGO 2025 guidelines✓ Statement of medical necessity for preventing ESRD✓ Confirmation of REMS program enrollment capability

Sample Medical Necessity Statement

Your doctor might write something like: "Based on persistent proteinuria of [X] g/g creatinine despite maximally tolerated ACE inhibitor therapy for [X] weeks, and in accordance with 2025 KDIGO guidelines for IgA nephropathy management, Filspari is medically necessary to reduce ongoing kidney damage and delay progression to end-stage renal disease."

Supporting Your Doctor Through Peer-to-Peer Review

If Cigna initially denies coverage, they may offer a peer-to-peer (P2P) review where your nephrologist speaks directly with a Cigna medical director. You can help your doctor prepare for this crucial conversation.

How to Support Your Doctor

Provide availability windows: Let your doctor know when you're available for urgent appointments if additional documentation is needed during the P2P process.

Prepare a concise case summary for your doctor to reference:

  • One-sentence diagnosis: "Biopsy-confirmed IgA nephropathy with proteinuria of [X] g/g"
  • Treatment failures: "Failed to achieve target proteinuria reduction on [medication] for [duration]"
  • Progression risk: "At high risk for ESRD based on [specific factors]"

Key Talking Points for Your Doctor

During P2P review, your nephrologist will emphasize:

  • Guideline compliance: Treatment aligns with current KDIGO recommendations
  • Medical necessity: Failure to treat increases ESRD risk
  • Safety monitoring: Committed to quarterly liver function monitoring through REMS program
  • Cost-effectiveness: Preventing dialysis/transplant justifies specialty drug cost

After Your Visit: Documentation and Follow-up

What to Save

Keep copies of:

  • Prior authorization submission confirmation
  • All correspondence with Cigna
  • Medical necessity letter (request a copy)
  • Lab results and test reports
  • Insurance denial letters (if any)

Patient Portal Communication

Use your doctor's patient portal to:

  • Share additional symptoms or concerns that arise
  • Report any insurance communication you receive
  • Ask for copies of submitted documentation
  • Request updates on authorization status
Note: Most prior authorization decisions from Cigna come within 5-10 business days. If you haven't heard anything after two weeks, contact both your doctor's office and Cigna member services.

Respectful Persistence: When and How to Follow Up

Follow-up Timeline

Week 1-2: Allow time for initial review Week 3: Contact doctor's office for status update Week 4+: If no response, help coordinate escalation

How to Escalate Politely

With your doctor's office: "I wanted to check on the status of my Filspari prior authorization. Is there anything additional I can provide to help move this forward?"

With Cigna member services: "I'm calling to check on prior authorization request [reference number]. Can you tell me what additional information, if any, is needed?"

When to Involve California Regulators

If you encounter unreasonable delays or denials, California offers robust consumer protections through the Department of Managed Health Care (DMHC).

California Appeal Process

California provides some of the strongest patient appeal rights in the nation. If Cigna denies your Filspari coverage, you have multiple levels of review available.

Internal Appeal (Required First Step)

Timeline: File within 180 days of denial Process: Submit written appeal with additional clinical evidence Decision timeframe: 30 days (72 hours if urgent)

Independent Medical Review (IMR)

When to file: After internal appeal denial or if Cigna doesn't respond in 30 days Cost: Free to patients Timeline: 30-45 days (7 days if expedited) Success rate: California IMR decisions favor patients in 35-60% of specialty drug cases

To request IMR:

From Our Advocates: We've seen several IgA nephropathy patients successfully overturn Cigna denials through California's IMR process. The key is providing comprehensive clinical documentation showing disease progression risk and treatment failure with standard therapies. While outcomes vary, California's independent reviewers often understand the complexity of rare kidney diseases better than initial insurance reviewers.

Costs and Patient Support

Filspari's list price of approximately $10,000 per month makes patient assistance crucial.
