FAQ

How long does UnitedHealthcare prior authorization take in Illinois? Standard requests: 24-72 hours for complete electronic submissions. Expedited requests: 24 hours when medically urgent.

What if Stelara is non-formulary on my plan? You can request a non-formulary exception with documentation of medical necessity and biosimilar trial failures. Success rate is high with proper documentation.

Can I request an expedited appeal in Illinois? Yes, if standard timelines could jeopardize your health. Your physician must certify the urgency, and UnitedHealthcare must respond within 72 hours.

Does step therapy apply if I was stable on Stelara from another state? Illinois has step therapy protection laws that may allow exceptions for patients stable on current therapy. Document your treatment history and response.

What's the difference between brand Stelara and biosimilars? Biosimilars (Steqeyma, Yesintek, Wezlana) have the same active ingredient as Stelara but may have different inactive ingredients. UnitedHealthcare prefers biosimilars for cost reasons.
