Why Illinois State Rules Matter

Illinois provides some of the strongest patient protections for insurance appeals in the country. Unlike many states, Illinois requires insurers to make internal appeal decisions within 15 business days for standard requests and 24 hours for urgent cases. More importantly, if Aetna denies your internal appeal, Illinois guarantees your right to an independent external review by a board-certified physician with expertise in your condition.

For specialty medications like Prolastin-C, these protections are crucial because denials often involve complex medical necessity determinations that benefit from independent clinical review. Illinois also has robust step therapy override protections that can help if Aetna requires you to try less expensive alternatives first.

Note: Self-funded employer plans (ERISA plans) are exempt from some state protections, though Aetna offers voluntary external review programs for these plans.

Aetna's Prior Authorization Requirements

Coverage at a Glance

Requirement What It Means Documentation Needed
Prior Authorization Required Must get approval before treatment Submit 2+ weeks in advance
Preferred Product Status Prolastin-C is preferred (with Zemaira) No step therapy typically required
AAT Level <11 micromol/L (80 mg/dL) Lab results from recent testing
Lung Function FEV1 25-80% of predicted Post-bronchodilator spirometry
Prescriber Requirement Must be pulmonologist Referral if needed

Source: Aetna Alpha1-Proteinase Inhibitor Policy

Medical Necessity Criteria

Aetna requires all of the following for Prolastin-C approval:

  1. Pretreatment serum alpha-1 antitrypsin (AAT) level <11 micromol/L (80 mg/dL by radial immunodiffusion or 50 mg/dL by nephelometry)
  2. Pretreatment post-bronchodilator FEV1 ≥25% and ≤80% of predicted value

While Aetna's published criteria don't explicitly require Pi*ZZ genotype documentation, submitting genetic testing results confirming severe AAT deficiency can strengthen your case, especially if your AAT levels are borderline.

How to Submit

  • Online: Availity portal for providers
  • Phone: (866) 752-7021
  • Fax: (888) 267-3277
  • Specialty drugs: Novologix portal

Include the Statement of Medical Necessity (SMN) form with all supporting documentation.


Illinois Turnaround Standards

Illinois law sets strict timelines that protect patients from lengthy delays:

Internal Appeals

  • Standard decisions: 15 business days maximum
  • Expedited appeals: 24 hours maximum
  • Pre-service requests: Must be processed promptly to avoid treatment delays

External Review Timeline

  • Filing deadline: 4 months from final adverse determination
  • IRO decision: 45 days for standard review, 72 hours for expedited
  • Cost: Free to consumers (insurers pay IRO fees)

These timelines apply to fully insured Aetna plans. Self-funded employer plans may follow different federal timelines but often adopt similar standards.


Step Therapy Protections in Illinois

Illinois law provides strong protections against inappropriate step therapy requirements. Aetna must accept written attestation from your healthcare provider if any of these conditions apply:

  1. Prior failure or intolerance: You've tried the preferred drug and it didn't work or caused adverse effects
  2. Contraindication: The step therapy drug is medically inappropriate for your condition
  3. Clinical ineffectiveness: Based on your medical history, the required drug is unlikely to be effective

Key Protection Language

When your pulmonologist submits documentation, they should use specific language that triggers Illinois protections: "The required prescription drug is contraindicated or will likely cause adverse reaction or physical harm" or "is expected to be ineffective based on known clinical history."

This language comes directly from Illinois regulations and requires Aetna to waive step therapy requirements.


Appeals Process: Internal to External Review

Step 1: Internal Appeal (Required First Step)

When Aetna denies your Prolastin-C request:

  1. File within 180 days of the denial notice
  2. Submit via: Member portal, phone, or written request
  3. Include: Denial letter, additional medical records, provider letter
  4. Decision timeline: 15 business days (24 hours if expedited)

Step 2: External Review (If Internal Appeal Fails)

Illinois guarantees independent review by a qualified physician:

  1. File within 4 months of final adverse determination
  2. Submit to: Illinois Department of Insurance
  3. Required forms: External Review Request form (available at idoi.illinois.gov)
  4. Decision: Binding on Aetna if reviewer approves coverage
Tip: You can file for external review even if Aetna delays beyond their internal appeal deadline (30 days for prospective review, 60 days for retrospective).

When and How to Escalate

Illinois Department of Insurance Resources

Illinois Attorney General Health Care Bureau

The Attorney General's office operates a Health Care Helpline that can intervene informally with insurers and help with complex appeal cases, particularly for rare medications requiring extensive supporting evidence.


Common Denial Reasons & Solutions

Denial Reason Solution Strategy Required Documentation
"Not medically necessary" Provide complete clinical picture AAT levels, spirometry, pulmonologist letter
"Experimental/investigational" Cite FDA approval and guidelines FDA labeling, ATS/ERS guidelines
"Non-formulary" Request formulary exception Medical necessity letter, prior failures
Inadequate documentation Submit comprehensive records Complete PFTs, genetic testing, smoking status
Site of care restriction Appeal infusion location limits Provider preference letter, access barriers

Practical Scripts and Templates

Patient Phone Script for Aetna

"I'm calling about a prior authorization denial for Prolastin-C. My policy number is [X]. I have severe alpha-1 antitrypsin deficiency with documented AAT levels below 11 micromol/L and lung function meeting your published criteria. I'd like to request an internal appeal and understand my rights under Illinois law for external review if needed."

Medical Necessity Letter Checklist for Providers

When writing appeals, include:

  • Diagnosis: Alpha-1 antitrypsin deficiency with emphysema (ICD-10: E88.01, J43.9)
  • Lab values: Specific AAT level and testing method
  • Lung function: FEV1 percentage with date of testing
  • Clinical rationale: Why Prolastin-C is medically necessary
  • Guidelines: Reference ATS/ERS recommendations for AAT augmentation
  • Monitoring plan: How treatment effectiveness will be assessed

Understanding ERISA Plan Limitations

If you have insurance through your employer, your plan may be self-funded and governed by federal ERISA law rather than Illinois state protections. Key differences:

ERISA Plans (Self-Funded)

  • External review: Federal process, not Illinois state process
  • Timeline: 4 months to file external review
  • Oversight: U.S. Department of Labor, not Illinois DOI

Fully Insured Plans

  • External review: Illinois state process with binding decisions
  • Timeline: Illinois-specific protections apply
  • Oversight: Illinois Department of Insurance

Check your Summary Plan Description or call Aetna at 1-800-872-3862 to confirm your plan type.


Frequently Asked Questions

How long does Aetna prior authorization take for Prolastin-C in Illinois? Standard prior authorizations typically take 30-45 days, but expedited requests for urgent cases can be processed within 72 hours. Submit requests at least 2 weeks before treatment start.

What if Prolastin-C is non-formulary on my plan? Request a formulary exception with medical necessity documentation. Since Prolastin-C is preferred on most Aetna plans, non-formulary status may indicate a plan-specific restriction requiring appeal.

Can I request an expedited appeal in Illinois? Yes, if a delay would seriously jeopardize your health. Both internal appeals (24-hour decision) and external reviews (72-hour decision) have expedited processes available.

Does step therapy apply if I've used Prolastin-C in another state? Prior successful treatment can support a step therapy override. Provide documentation of previous use and clinical response to strengthen your case.

What happens if the external review approves coverage? The decision is binding on Aetna - they must provide coverage as determined by the independent reviewer. This typically resolves coverage disputes definitively.
