What Affects Filspari Approval Timing

Several factors influence how quickly UnitedHealthcare approves Filspari (sparsentan) in Michigan:

Benefit Type & Plan Structure

  • Commercial plans: Standard 15-day review period under Michigan insurance law
  • Medicare Advantage: Must follow CMS guidelines for specialty drug authorization
  • Medicaid managed care: Additional state oversight may extend timelines

Complexity of Clinical Criteria Filspari requires extensive documentation due to its REMS program requirements and specialty status. UnitedHealthcare typically requires:

  • Confirmed IgA nephropathy diagnosis with supporting labs
  • Step therapy documentation showing ACE inhibitor or ARB failure
  • REMS enrollment completion for both prescriber and patient
  • Quarterly liver function monitoring plan

Documentation Completeness OptumRx's automated PreCheck system can approve qualifying specialty medications in a median time of 29 seconds, but Filspari may not qualify for full automation due to REMS requirements.

Note: UnitedHealthcare's Medicare Advantage plans showed a ~9% prior authorization denial rate in 2023, higher than peer average, making thorough preparation crucial.

Pre-Submission Preparation (1-5 Days)

REMS Enrollment Requirements Before any prior authorization submission, complete the mandatory REMS program:

  1. Prescriber enrollment: Submit Prescriber Enrollment Form with required training completion
  2. Patient enrollment: Complete Patient Enrollment Form documenting counseling on hepatotoxicity risks
  3. Baseline testing: Obtain liver function tests (ALT/AST) before first dose

Clinical Documentation Checklist

  • IgA nephropathy diagnosis with biopsy confirmation (if available)
  • eGFR and UPCR values demonstrating disease progression risk
  • Documentation of ACE inhibitor or ARB trial with failure, contraindication, or intolerance
  • Current medication list and dosing rationale

This approach typically reduces approval time by 3-5 days and decreases the likelihood of initial denial.

Step therapy not met Document ACE inhibitor/ARB failure or contraindication Clinical notes with specific therapy details and outcomes
