Set Your Goal: Understanding What Approval Requires

UnitedHealthcare requires prior authorization through OptumRx for Dupixent across all FDA-approved indications. The median approval time is 29 seconds when all criteria are met, but incomplete submissions can take weeks.

Coverage Requirements by Indication

Indication Key Requirements Authorization Duration
Atopic Dermatitis Moderate-to-severe diagnosis; failed topical therapies (30+ days) 12 months
Asthma Eosinophilic phenotype (≥300 cells/μL) OR oral steroid dependence; failed inhaled corticosteroids 12 months
Chronic Rhinosinusitis Symptoms >12 weeks; prior surgery OR systemic steroids OR failed nasal agents 12 months
COPD Eosinophilic phenotype with elevated eosinophils; combination with maintenance therapy 12 months

Your partnership goal: Work with your provider to create a comprehensive clinical narrative that demonstrates medical necessity and meets UnitedHealthcare's specific criteria.

Tip: Request a copy of your insurance benefits summary before your appointment. Look for your prescription drug formulary tier for Dupixent and any step therapy requirements.

Visit Preparation: Building Your Clinical Story

Come prepared with a detailed timeline that helps your provider document the progression of your condition and treatment failures.

Symptom Timeline Preparation

Create a chronological record including:

  • Date of initial diagnosis and who made it
  • Baseline severity measurements (body surface area for atopic dermatitis, eosinophil counts for asthma)

Treatment History Documentation

For each prior therapy, note:

Side Effects and Contraindications

Document any adverse reactions to previous treatments, including:

  • Allergic reactions or hypersensitivity
  • Significant side effects that required discontinuation
  • Drug interactions with other medications
  • Medical conditions that contraindicate certain therapies
Note: If you've received treatment in other states, this history typically counts toward Michigan step therapy requirements. Bring all out-of-state medical records.
