Q: How long does UnitedHealthcare prior authorization take in Texas? A: Standard PA decisions take 3-5 business days. Expedited reviews for urgent cases are completed within 72 hours.
Q: What if Firdapse is non-formulary on my plan? A: Firdapse appears on most 2024-2025 UHC formularies with prior authorization. If non-formulary, request a formulary exception with your appeal.
Q: Can I request an expedited appeal? A: Yes, if delaying treatment would seriously jeopardize your health or if you're currently on Firdapse and coverage is being stopped.
Q: Does step therapy apply to Firdapse? A: No, UnitedHealthcare's current policy does not require step therapy for Firdapse in confirmed LEMS cases.
Q: What happens if my employer plan is self-funded? A: Self-funded ERISA plans follow federal, not Texas, appeal rules. They must still provide external review, but through a federal process rather than Texas IRO.
Q: How successful are Firdapse appeals? A: External reviews have approximately 50% success rates for prior authorization appeals when proper clinical documentation is provided.
