    • Hand stereotypies and other Rett features
  • Rett Syndrome Clinical Severity Scale (RSSS) score between 10-36
  • Weight-based dosing calculation per FDA labeling

Clinician Corner: Medical necessity letters should explicitly state "patient exhibits ≥2 characteristics suggestive of Rett syndrome, specifically regression and gait abnormalities" to align with Humana's genetic testing criteria.

Specialty Pharmacy Network

Required Dispensing Humana treats Daybue as a specialty pharmacy benefit, typically requiring dispensing through AnovoRx or other designated specialty pharmacies.

Setup Process

  1. Prescriber submits PA with specialty pharmacy designation
  2. Pharmacy contacts patient for enrollment and shipping coordination
  3. Specialty pharmacy manages refills and adherence monitoring

Key Considerations

  • Specialty pharmacy must be indicated on PA request
  • Patient enrollment required before first shipment
  • Automatic refill programs available for ongoing therapy

Cost-Share Dynamics

Typical Cost Pattern (Medicare Advantage)

  • Before Deductible: 100% of negotiated cost until deductible met
  • Initial Coverage: 25-33% coinsurance on specialty tier
  • Coverage Gap: Same specialty tier coinsurance applies
  • Catastrophic: Significantly reduced cost-sharing after out-of-pocket maximum

2024 Medicare Part D Framework

  • Plans may have deductibles up to CMS maximum
  • Specialty tier drugs typically subject to percentage coinsurance
  • High-cost drugs like Daybue often reach catastrophic coverage quickly
Important: Exact cost-sharing varies by specific Humana plan. Use MyHumana's cost estimator for your plan-specific copay amounts.

FAQ

How long does Humana PA take in New York? Standard PA decisions take up to 14 calendar days in 2024 (7 days starting 2025). Expedited reviews are completed within 72 hours when delay could seriously harm health.

What if Daybue is non-formulary on my plan? Submit a formulary exception request with medical necessity documentation. Use the same clinical criteria as PA requirements, emphasizing FDA-approved indication and lack of therapeutic alternatives.

Can I request an expedited appeal? Yes, if waiting could seriously jeopardize health. Your prescriber must state this in writing and explain the medical urgency. Expedited appeals receive decisions within 72 hours.

Does step therapy apply to Daybue? Daybue is the first and only FDA-approved therapy for Rett syndrome, so traditional step therapy typically doesn't apply. However, Humana may require documentation that supportive therapies are being continued.

What happens if I move from another state to New York? Your Humana coverage continues, but you gain access to New York's external appeal rights. Any ongoing appeals can be supplemented with DFS external review options.

How often do I need reauthorization? Annual reauthorization is typically required. Submit renewal PA 30 days before expiration with updated clinical notes, repeat severity scores, and documentation of continued benefit.
