Why Illinois State Rules Matter

Illinois has some of the strongest patient protection laws in the country when it comes to insurance appeals and coverage denials. These state regulations work alongside your Aetna (CVS Health) plan policies to ensure you get fair treatment when seeking coverage for specialty medications like Opfolda (miglustat).

Key Illinois advantages:

  • 4-month external review window (longer than many states)
  • Free consumer assistance through the Illinois Department of Insurance
  • Binding external review decisions that insurers must honor
  • Step therapy protections for certain medical conditions
  • Expedited review options for urgent medical needs
Note: These protections apply to state-regulated plans. If you have coverage through a large employer's self-funded plan (governed by ERISA), some Illinois protections may not apply, but federal appeal rights still exist.

Aetna (CVS Health) Prior Authorization Requirements

Opfolda (miglustat) is a specialty medication that requires prior authorization from Aetna (CVS Health). The drug is only FDA-approved for use in combination with Pombiliti for adults with LOPD who aren't improving on current enzyme replacement therapy.

Required Documentation

Your prescriber must submit:

  • Confirmed LOPD diagnosis with genetic testing or enzyme assay results
  • Evidence of inadequate response to current ERT (Lumizyme, Nexviazyme, or similar)
  • Weight verification (patient must be ≥40 kg)
  • Age confirmation (≥18 years)
  • Specialist evaluation from a metabolic or lysosomal storage disorder specialist
  • Prescription for both drugs (Opfolda cannot be prescribed alone)

How to Submit

Provider Portal: Aetna Availity Portal Phone: 1-866-814-5506 (Specialty Precertification) Fax: 1-855-330-1716

From our advocates: "We've seen the fastest approvals when specialists submit complete documentation upfront, including functional assessment scores like 6-minute walk distance and forced vital capacity measurements. These objective measures help demonstrate why the current ERT isn't working."

Illinois Turnaround Standards and Timelines

Illinois law requires insurers to respond to prior authorization requests within specific timeframes:

Standard Requests

  • Non-urgent: 15 business days for pre-service requests
  • Post-service: 30 calendar days

Expedited Requests

  • Urgent medical needs: 24 hours
  • Emergency situations: Immediate coverage required

What qualifies as urgent: If waiting for the standard review timeline could seriously jeopardize your health or ability to regain maximum function.

Step Therapy Protections in Illinois

Illinois has enacted step therapy reform laws that protect patients in certain situations. For Opfolda (miglustat), step therapy overrides must be granted if:

  • The required first-line ERT is contraindicated
  • You've already tried and failed the required ERT
  • You're currently stable on your prescribed therapy

Documentation for Step Therapy Override

Include in your medical necessity letter:

  • Detailed history of ERT trials with specific drugs, doses, and duration
  • Objective measures of treatment failure (functional assessments, biomarkers)
  • Any adverse reactions or contraindications to formulary alternatives
  • Clinical rationale for why Opfolda/Pombiliti combination is necessary

Timeline: Insurers must respond to step therapy exception requests within 72 hours for standard cases and 24 hours for emergencies.

Practical Scripts and Templates

Patient Phone Script for Aetna (CVS Health)

"Hi, I'm calling about a prior authorization denial for Opfolda, which is prescribed with Pombiliti for my late-onset Pompe disease. My doctor has documented that I'm not improving on my current enzyme replacement therapy, and this combination is FDA-approved for patients like me. I'd like to request an expedited internal appeal because any delay in treatment could worsen my condition. Can you help me start that process today?"

Medical Necessity Letter Template

"This patient has confirmed late-onset Pompe disease (ICD-10: E74.02) with genetic testing showing [specific mutation]. Despite [X months] of treatment with [current ERT drug and dose], the patient demonstrates inadequate clinical response as evidenced by [specific functional decline measures].
