Why Illinois State Rules Matter

Illinois has some of the strongest patient protections in the country for specialty drug access. As of January 2025, Illinois banned step therapy protocols for specialty medications like Gattex, meaning Blue Cross Blue Shield of Illinois can't force you to try cheaper alternatives first if your doctor prescribes teduglutide for short bowel syndrome.

However, this protection only applies to fully-insured plans. If your employer self-funds their health plan (common with large companies), federal ERISA law takes precedence, and the Illinois step therapy ban won't apply. About 63% of Illinois commercial insurance is held by Blue Cross Blue Shield of Illinois, making these state protections relevant for most residents.

The Illinois Department of Insurance also provides robust appeal rights, including independent external review by board-certified physicians and strict timelines that insurers must follow.

Illinois Step Therapy Protections

Illinois House Bill 5395, effective January 1, 2025, prohibits step therapy for specialty medications in fully-insured plans. This means:

What's Protected

  • Specialty drugs like Gattex are exempt from step therapy requirements
  • Rare disease medications can be prescribed without trying cheaper alternatives first
  • Provider discretion is respected for medically appropriate treatments

What's Not Protected

  • Self-insured/ERISA plans (check with your HR department)
  • Prior authorization requirements still apply
  • Medical necessity must still be demonstrated
Important: If your BCBS Illinois plan tries to enforce step therapy for Gattex after January 2025, and you have a fully-insured plan, contact the Illinois Department of Insurance at 877-527-9431 to report the violation.

Appeal Deadlines and Turnaround Standards

Illinois law sets strict timelines that Blue Cross Blue Shield must follow:

Internal Appeals

  • Filing deadline: 60 days from denial notice
  • Insurer response time: 15 business days for standard appeals
  • Expedited appeals: 24 hours if delay risks health

External Review

  • Filing deadline: 4 months from final internal denial
  • IRO decision time: 5 business days after receiving records
  • Expedited external review: 72 hours for urgent cases

Automatic Approval

If BCBS Illinois fails to respond within required timeframes, your request may be automatically approved under state regulations.

External Review Process

When internal appeals fail, Illinois provides independent external review through board-certified physicians:

How It Works

  1. Request external review within 4 months of final denial
  2. Illinois Department of Insurance assigns an Independent Review Organization (IRO)
  3. IRO physician (with relevant expertise) reviews your case
  4. Decision is binding - if overturned, BCBS must cover treatment

  • Consumer Assistance: 877-527-9431 (Monday-Friday, 8:30 AM-5:00 PM)

FAQ

How long does BCBS Illinois prior authorization take for Gattex? Standard PA decisions must be made within 72 hours. Expedited requests (when delay risks health) get 24-hour turnaround.

What if Gattex isn't on my BCBS Illinois formulary? You can request a formulary exception using their exception form. Include clinical justification for why formulary alternatives aren't appropriate.

Can I get an expedited appeal if I'm already on Gattex? Yes, if stopping treatment would jeopardize your health. Document current clinical stability and risks of interruption.

Does the Illinois step therapy ban apply to Medicare plans? No, Medicare is federally regulated. The Illinois ban only affects fully-insured commercial and individual plans.

What happens if BCBS Illinois denies my external review? External review decisions by Independent Review Organizations are binding. If the IRO overturns the denial, BCBS must provide coverage.

How do I know if my plan is self-insured (ERISA)? Check with your HR department or look for "ERISA" language in your benefits documents. Self-insured plans aren't subject to Illinois state protections.
