Why Illinois State Rules Matter

Illinois provides some of the strongest patient protections in the nation for specialty drug coverage. Unlike many states, Illinois has enacted comprehensive reforms that directly impact how Aetna CVS Health must handle your Poteligeo (mogamulizumab-kpkc) request.

Key Illinois advantages:

  • Step therapy ban: Starting January 1, 2025, Illinois prohibits step therapy requirements for most fully insured plans, meaning you may not need to "fail first" on cheaper alternatives
  • Automatic external review: Medical necessity denials are automatically forwarded for independent physician review unless you opt out
  • Binding decisions: Independent reviewers' decisions are legally binding on Aetna, with up to $50,000 penalties for non-compliance
  • Continuity protections: New laws require maintaining access to specialty drugs during insurance transitions
Note: Self-funded employer plans (ERISA) may not be subject to all Illinois protections, but you still have federal appeal rights.

Aetna CVS Health Prior Authorization Requirements

Aetna's published criteria for mogamulizumab align with FDA labeling but require specific documentation:

Approved indications:

  • Mycosis fungoides (MF)
  • Sézary syndrome (SS)
  • Adult T-cell leukemia/lymphoma (ATLL) as subsequent therapy

Required documentation:

  • Confirmed histologic diagnosis of MF or SS
  • At least one prior systemic therapy failure (methotrexate, retinoids, interferons, HDAC inhibitors, brentuximab vedotin, or chemotherapy)
  • ECOG performance status 0 or 1
  • Adequate organ function (hematologic, hepatic, renal)
Important: PUVA (psoralen plus UV-A) does not count as systemic therapy under Aetna's criteria.

Illinois Turnaround Standards and Deadlines

Illinois law sets strict timelines that Aetna must follow:

Prior Authorization Decisions:

  • Standard requests: 15 business days maximum
  • Expedited/urgent: 24-72 hours
  • Incomplete submissions: 5 business days to request additional information

Internal Appeals:

  • Pre-service requests: 15 business days
  • Post-service requests: 30 calendar days
  • Expedited appeals: 24 hours

External Review:

  • Standard review: 30 days from IRO receiving materials
  • Expedited review: 72 hours for urgent medical needs
  • Filing deadline: 4 months from final internal denial
Tip: Mark all requests as "expedited" if disease progression could occur during standard review timelines.

Step Therapy Protections in Illinois

Starting January 1, 2025, Illinois bans step therapy requirements for most health plans. This significantly strengthens your position if Aetna requires trying cheaper alternatives first.

Medical exception criteria (for plans still requiring step therapy):

  • Previous adverse reaction to formulary alternatives
  • Contraindication to step therapy drugs
  • Formulary drug ineffective based on medical history
  • Patient stable on current non-formulary therapy

Exception timeline: Plans must decide within 2 business days (non-urgent) or 24 hours (urgent).

Documentation phrases that help:

  • "Patient previously failed [specific drug] due to [specific adverse event/lack of efficacy]"
  • "Contraindicated due to [medical condition/drug interaction]"
  • "Disease progression documented while on [alternative therapy]"

Continuity of Care During Plan Changes

Illinois's new Prescription Drug Affordability Act requires insurers to maintain specialty drug access during coverage transitions. If you're switching from another plan or losing coverage:

Grace period protections:

  • Temporary continued access to current specialty therapy
  • Cannot unreasonably designate drugs as "specialty" to limit access
  • Applies to plans issued/renewed after January 1, 2026

Actionable steps:

  • Notify new insurer immediately about ongoing Poteligeo therapy
  • Request written continuity-of-care policy from health plan
  • File appeal citing Illinois law if access is interrupted during transition

External Review and State Complaints

Illinois provides multiple pathways when Aetna denies coverage:

Independent External Review:

  • File within 4 months of final internal denial
  • Submit online or by mail to Illinois Department of Insurance
  • IRO assigns physician with relevant specialty expertise
  • Decision is binding on Aetna with $50,000 penalty for non-compliance
  • No cost to consumer

Required documentation for external review:

  • Copy of final denial letter from Aetna
  • All medical records supporting medical necessity
  • Completed external review application
  • Any additional clinical evidence not previously submitted

Consumer assistance programs:

  • Illinois Department of Insurance OCHI: (877) 527-9431
  • Illinois Attorney General Health Care Bureau: (877) 305-5145
