Key action: Ensure the lab report explicitly states your variant is "amenable to migalastat" based on in-vitro assay data.

Tip: Illinois screens newborns for Fabry disease, but adult testing requires specific GLA sequencing. Ann & Robert H. Lurie Children's Hospital in Chicago is a leading center for Fabry care in Illinois.

Who does it: Patient and clinic staff
What's needed:

  • Complete genetic testing report
  • Baseline kidney function (eGFR, proteinuria)
  • Documentation of any prior enzyme replacement therapy
  • Current symptom assessment and treatment goals

Timeline: 1 week to compile
Source: Aetna's Galafold clinical policy outlines exact requirements.

3. Submit Prior Authorization

Who does it: Prescribing specialist's office
How to submit:

  • Online via Aetna provider portal
  • Fax to specialty PA line: 1-866-249-6155

Expected decision: Up to 14 days standard, 72 hours expedited

4. Monitor and Follow Up

Who does it: Patient and clinic
What to track: PA reference number, decision timeline, any requests for additional information
Key action: If no response within expected timeframe, call Aetna Provider Services to check status.

Appeals Playbook for Aetna in Illinois

Internal Appeal Process

Deadline: 180 days from denial notice
How to file:

  • Online through member portal
  • Written letter to address on denial notice
  • Call member services for expedited appeals

Timeline:

  • Standard: 30 calendar days for decision

Peer-to-Peer Review

When to request: Immediately after denial, before or during written appeal
Who calls: Your specialist's office
What to ask for: "Peer-to-peer review with the medical director who reviewed this Galafold case"
Preparation: Have Aetna's Galafold policy and patient's records ready to reference specific criteria

From our advocates: In our experience, specialists who structure their peer-to-peer calls around Aetna's exact policy language—especially the amenable variant requirement—see significantly higher overturn rates. The key is addressing each denial reason with specific clinical evidence.

External Review (Illinois)

When available: After final internal denial
Deadline: 30 days from final adverse determination (shorter than many states)
How to file: Through Illinois Department of Insurance
Contact: Illinois DOI Office of Consumer Health Insurance at 877-527-9431
Timeline: Decision within 5 business days after review starts
Cost: Free to consumers; binding decision

Illinois advantage: The state's external review law requires independent physician reviewers with relevant expertise, and decisions typically favor patients when medical criteria are clearly met.

FAQ: Common Questions

Q: How long does Aetna prior authorization take for Galafold in Illinois?
A: Standard decisions within 14 days; expedited reviews within 72 hours if delay would jeopardize health. Submit at least 2 weeks before needed start date.

Q: What if my GLA variant isn't on the amenable list?
A: Galafold is only FDA-approved for amenable variants. Non-amenable variants require enzyme replacement therapy (Fabrazyme or Elfabrio) instead.

Q: Can I appeal if Aetna requires step therapy with ERT first?
A: Yes. Document medical reasons why ERT is inappropriate (infusion reactions, venous access issues, lifestyle factors) or provide evidence of prior ERT failure.

Q: Does Illinois have special protections for rare disease coverage?
A: Illinois has strong external review laws with 30-day deadlines and independent physician reviewers. The state also expanded Medicaid, providing additional coverage options.

Q: What happens if I'm denied during external review?
A: External review decisions are binding in Illinois. If denied, consider whether new evidence (disease progression, additional testing) might support a new PA request.

Q: How do I verify my Aetna plan covers specialty drugs like Galafold?
A: Check your formulary or call member services. Most Aetna commercial plans cover Galafold with prior authorization, but tier placement and copays vary.

Q: Can I start Galafold while an appeal is pending?
A: Contact Galafold Connect for bridge therapy options. Some patients may qualify for free drug while appeals are processed.

Q: What if my specialist isn't in Aetna's network?
A: Request a network exception for rare disease care, or ask for referral to an in-network Fabry specialist. Illinois law supports access to appropriate specialty care.
