Why Illinois State Rules Matter

Illinois insurance laws work alongside UnitedHealthcare's policies to protect patients seeking rare disease treatments like Onpattro. The state's Health Carrier External Review Act ensures that if UnitedHealthcare denies your appeal, an independent specialist physician—not an insurance company employee—makes the final decision.

Key Illinois protections:

  • Automatic external review for medical necessity denials (effective April 2025)
  • Step therapy medical exceptions within 72 hours for standard requests
  • Binding specialist review by actively practicing physicians in your condition
  • No cost to patients for external reviews

These state rules apply to most commercial UnitedHealthcare plans, but not self-funded employer plans (ERISA) or federal programs like Medicare.

Step Therapy Protections in Illinois

Illinois' step therapy law requires UnitedHealthcare to grant medical exceptions when:

  1. The required drug is contraindicated for your specific condition
  2. You've tried and failed a step therapy drug previously
  3. You're stable on your current prescription (for existing patients)

Medical Exception Request Process:

  • Submit through UnitedHealthcare's standard PA system
  • Include specific clinical documentation of contraindications or failures
  • Decision required within 72 hours (24 hours if expedited)
  • Cost considerations alone cannot justify denial

Documentation phrases that help:

  • "Patient experienced intolerable side effects with [step therapy drug]"
  • "Contraindicated due to [specific medical condition/interaction]"
  • "Patient clinically stable on current regimen with demonstrated improvement"

External Review & State Protections

  • Binding decisions: UnitedHealthcare faces up to $50,000 penalties for non-compliance
  • No premium increases allowed based on external review usage

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
No genetic confirmation Submit complete genetic testing report TTR gene sequencing with pathogenic variant identification
Missing neurologist evaluation Obtain specialist consultation Clinical assessment with PND/FAP staging, mNIS+7 scoring
Insufficient disease staging Update clinical documentation Functional status scores showing Stage I-II disease
Step therapy not attempted Request medical exception or document failures Prior therapy records, contraindication documentation
Not medically necessary Strengthen clinical justification Progressive symptoms, treatment goals, guideline citations

Sample appeal language for medical necessity:

"Patient has genetically confirmed hATTR polyneuropathy with progressive sensorimotor symptoms documented by mNIS+7 score of [X]. Current PND staging of [I/II] indicates appropriate disease stage for Onpattro therapy per FDA labeling and clinical guidelines. Patient meets all UnitedHealthcare medical policy criteria as outlined in policy [reference number]."
