New to helping someone in Missouri?
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. Use the name and phone number on the card when you call or file paperwork (it may differ from an employer or clinic name).
- 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. On an EOB alone, search for words like "denied," "adverse determination," or "appeal."
- Summary of Benefits and Coverage (SBC) — a plain-language summary of what the plan covers. It 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 (Marketplace, job-based, MO HealthNet, Medicare) and write down the appeal deadline from the letter. Missing a deadline is one of the most common reasons people lose appeals they could have won.
Missouri carriers use terms like adverse determination and utilization review. You usually appeal first with the insurance company (internal appeal or grievance). If that fails, you may request external review through the Missouri Department of Commerce and Insurance (DCI).
For steps that work in every state, read these general guides first, then return here for Missouri rules:
- Denial decoder — what the denial letter is actually saying
- Appeals roadmap — internal appeal, then external review
- Building a strong appeal packet — records and letters to gather
What is different in Missouri?
- HealthCare.gov Marketplace: Missouri uses the federal Marketplace at HealthCare.gov. Marketplace insurers include Anthem (Healthy Alliance), Medica, Ambetter/Home State Health, UnitedHealthcare, and others. Blue Cross Blue Shield of Kansas City and some carriers also sell off-exchange plans.
- Prior authorization (RSMo §§ 376.1363–376.1372): 36 hours for prospective review (includes one working day) / 1 working day for concurrent review; PA list and criteria must be on the carrier website; valid PA generally cannot be revoked for 45 working days.
- Internal appeals: Group plans often have two appeal levels; many individual plans have one or two—check your policy. Federal timelines often apply (e.g., 30 days preservice / 60 days post-service for exhaustion).
- DCI external review: Independent Review Organization (IRO) assigned by DCI; file within 4 months under federal rules; up to 45 days standard / 72 hours expedited. DCI suggests internal appeals first but does not require them.
- MO HealthNet: MCO appeal first, then state fair hearing with the Division of Medicaid—separate from DCI external review.
Who is in charge of your plan?
The right agency depends on plan type. When in doubt, call member services and ask whether the plan is "fully insured in Missouri" or "self-funded ERISA."
- DCI (Department of Commerce and Insurance): External review, carrier regulation, appeal assistance — insurance.mo.gov. Insurance Consumer Hotline: 800-726-7390.
- U.S. Department of Labor: Many self-funded employer plans.
- MO HealthNet Division: Medicaid managed care and fair hearings — medicaid.ms.gov, 800-392-2161 (state fair hearing help).
- CMS: Medicare and Medicare Advantage.
