Renewal Triggers: When to Start Early

Your Filspari authorization expires exactly 12 months from approval. Start renewal preparations 60-90 days early if you notice these triggers:

Clinical Indicators:

  • UPCR hasn't decreased by ≥30% from baseline
  • eGFR declining faster than expected (>1 mL/min/1.73m² annually)
  • New side effects or tolerability issues
  • Changes in other medications affecting kidney function

Administrative Red Flags:

  • Missed quarterly liver function tests
  • REMS enrollment lapsing
  • Pharmacy benefit changes or plan switches
  • Provider changes requiring new specialist consultation
Tip: UnitedHealthcare's OptumRx system typically sends renewal reminders 30 days before expiration, but don't wait—formulary changes can affect approval criteria.

Evidence Update: Documenting Clinical Response

Primary Response Markers (Required):

  • Proteinuria reduction: Document UPCR improvement from baseline. Target: ≥30% reduction by 9 months, ideally reaching <0.5 g/g
  • eGFR stability: Show preserved kidney function or slower decline compared to pre-treatment trajectory
  • Blood pressure control: Document stable BP, especially if on concurrent RAAS inhibitors

Supporting Clinical Data:

  • Complete metabolic panel within 30 days
  • Liver function tests (ALT, AST, bilirubin) from most recent quarterly monitoring
  • Medication adherence documentation
  • Adverse event reporting (or lack thereof)

Updated Medical History:

  • Any new diagnoses affecting kidney function
  • Changes in concomitant medications
  • Hospitalizations or emergency department visits
  • Specialist consultations and recommendations
Note: The 2025 KDIGO guidelines now emphasize UPCR targets <0.5 g/g rather than the previous <1 g/g threshold.

FAQ

Q: How long does Filspari renewal take with UnitedHealthcare in Illinois? A: Standard renewals typically take 15 business days, but can extend to 30 days if additional documentation is requested. Start the process 60 days early to avoid gaps.

Q: What happens if I miss quarterly liver function tests? A: REMS non-compliance can trigger immediate authorization suspension. Contact your prescriber immediately to schedule overdue labs and document catch-up monitoring.
