  • Dupixent (dupilumab) - Preferred for eosinophilic asthma in many plans
  • Xolair (omalizumab) - May be required trial for allergic asthma phenotypes

Formulary Lookup: Verify Nucala's status on your specific plan through the UnitedHealthcare formulary search tool (verify current link with member services).

Prior Authorization & Step Therapy Requirements

Medical Necessity Criteria

UnitedHealthcare requires documentation of:

For Severe Eosinophilic Asthma:

  • Age 6 years or older
  • Blood eosinophil count ≥150 cells/µL at initiation OR ≥300 cells/µL within past 12 months
  • Inadequate control on high-dose inhaled corticosteroids plus additional controller

Step Therapy Requirements

Most UnitedHealthcare plans require documented trial and failure (or contraindication) of preferred alternatives before approving Nucala. Common step therapy sequence:

  1. First-line: Optimized inhaled therapy (ICS/LABA combination)
  2. Second-line: Preferred biologic (often Fasenra or Dupixent)
  3. Third-line: Nucala approval after documented failure of preferred options

Exception Process: Step therapy can be bypassed with documentation of contraindications, previous intolerance, or clinical reasons why preferred alternatives are inappropriate.

Specialty Pharmacy Network

UnitedHealthcare requires Nucala to be dispensed through approved specialty pharmacies:

In-Network Specialty Pharmacies:

  • Optum Specialty Pharmacy (UnitedHealth's own specialty pharmacy)
  • Accredo Health Group
  • Amber Specialty Pharmacy

Patient Enrollment Process:

  1. Prior authorization approval obtained
  2. Prescription sent to designated specialty pharmacy
  3. Specialty pharmacy contacts patient for enrollment
  4. Benefit verification and copay assistance coordination
  5. Delivery scheduling (home or provider office)
Note: Patients cannot choose any specialty pharmacy - your specific UnitedHealthcare plan designates which pharmacy must be used for coverage.

Cost-Share Structure

Nucala's cost-sharing depends on your plan's specialty tier structure:

Typical Cost-Sharing by Plan Type:

  • Commercial Plans: 20-40% coinsurance after deductible
  • Medicare Advantage: Varies by plan, often $200-400+ per month
  • Medicaid: Typically minimal copay ($1-3) if covered

FAQ

How long does UnitedHealthcare prior authorization take for Nucala in Illinois? Standard prior authorization decisions are made within 15 business days. Urgent requests may be processed within 24-72 hours if clinical urgency is documented.

What if Nucala is non-formulary on my UnitedHealthcare plan? You can request a formulary exception with strong clinical documentation showing medical necessity and why formulary alternatives are inappropriate. This requires detailed clinical rationale from your prescriber.

Can I request an expedited appeal in Illinois? Yes, both UnitedHealthcare internal appeals and Illinois external reviews can be expedited if delays would seriously jeopardize your health. Document the clinical urgency clearly.

Does step therapy apply if I tried alternatives before moving to Illinois? Previous treatment history from other states should count toward step therapy requirements. Ensure your provider includes complete treatment records in the prior authorization submission.

What happens if UnitedHealthcare denies my external review request? External review decisions are binding in Illinois. If UnitedHealthcare fails to comply with a favorable external review decision, contact the Illinois Department of Insurance for enforcement.

From our advocates: We've seen Nucala approvals succeed when providers include specific eosinophil trends over time rather than single lab values, and document concrete functional improvements or exacerbation reduction goals. This composite approach helps demonstrate both biomarker criteria and clinical necessity.

When navigating complex specialty drug approvals, having expert support can make the difference between denial and approval. Counterforce Health helps transform insurance obstacles into successful outcomes by providing targeted, evidence-based appeal strategies tailored to specific payer policies and state requirements.
