New to helping someone in Wyoming?
You do not need a law degree to help someone fight a health insurance denial. Start by gathering three basic documents:
- Insurance card — shows which company administers the plan (often Blue Cross Blue Shield of Wyoming or UnitedHealthcare on the Marketplace).
- Denial letter or explanation of benefits (EOB) — the notice that says a service was denied, not paid, or needs approval first. Look for appeal instructions and a deadline.
- Summary of Benefits and Coverage (SBC) — helps you tell whether the fight is about medical necessity or whether the benefit exists at all.
Your first tasks: identify what type of plan this is (HealthCare.gov, job-based, Wyoming Medicaid, Medicare) and write down the appeal deadline from the letter.
For many Wyoming-regulated plans denied as not medically necessary, you have an internal review with the insurer first, then a right to external review by a Department of Insurance–registered IRO under W.S. 26-40-201 and Insurance Department Regulation Chapter 63.
For steps that work in every state, read these general guides first, then return here for Wyoming rules:
What is different in Wyoming?
- HealthCare.gov: Wyoming uses the federal Marketplace. For 2026, major carriers are Blue Cross Blue Shield of Wyoming and UnitedHealthcare (Mountain Health CO-OP exited at end of 2025). Free enrollment help: Enroll Wyoming.
- Prior authorization:Wyoming's Ensuring Transparency in Prior Authorization Act (W.S. 26-55)—5 calendar days / 72 hours urgent decisions, peer-to-peer within 5 business days, gold carding (§ 26-55-112) effective January 1, 2026 (90% approval on 5+ requests per service).
- Internal appeals: For medical-necessity denials, Wyoming regulations often require filing internal review within 30 days; insurer decision often within 45 days (72 hours if expedited). Federal ACA plans may also allow up to 180 days—follow your denial letter.
- External review: Medical-necessity denials only—file within 120 days of final internal denial (or after 45 days without a final decision); insurer assigns DOI-registered IRO; 45 days standard / 72 hours expedited; binding on insurer; review is free (a small filing fee may apply per Chapter 63).
- Wyoming Medicaid: Administrative fair hearing through Office of Administrative Hearings—often 30 days from notice—not commercial IRO review.
