How to Find the Cheapest Health Insurance in Missouri
Follow these steps to find affordable health insurance in Missouri:
- 1
Determine coverage plan needs and affordability
Your coverage plan type and tier will differ widely depending on your personal health circumstances and income. Calculate how much income you can set aside for monthly premiums, considering your current health and risk for injury or disease based on location, age and lifestyle.
- 2
Find out your subsidy eligibility
People earning between $14,580 and $54,000 may qualify for premium tax credits, reducing costs by 40% to 100%. Those with incomes below 250% of the Federal Poverty Level ($36,450) can access cost-sharing reductions, decreasing out-of-pocket expenses up to 73%.
- 3
Consider federal programs for eligible age groups
If you're of suitable age, explore Medicare Advantage plans and Medicare Supplement plans. These plans may offer more affordable and flexible alternatives to traditional plans.
- 4
Review prescription formularies
Check insurers' prescription coverage for medications you regularly take. Choosing plans with lower-tier placements and reduced copays for your medications can optimize savings and ensure consistent and affordable access to necessary prescriptions, saving you hundreds of dollars each year.
- 5
Compare plans during Open Enrollment
Take advantage of Open Enrollment from November 1 to January 15, or Special Enrollment under certain conditions, like job loss or changes in family size. Evaluate plan types, costs, customer reviews and network availability to find the most suitable and affordable coverage for your circumstances.
MONEYGEEK TIP: MAKE SURE TO APPLY PROMPTLY
To avoid technical issues, apply for coverage at least five days before the enrollment deadline. Prepare your income verification, Social Security numbers and immigration documents to ensure a smooth application process.
Most Affordable Health Insurance in Missouri: Bottom Line
Missouri's most affordable health insurance companies are Cox HealthPlans, Medica, Oscar, Aetna and Anthem (BCBS). While we recommend these affordable options, you should compare as many plan types and tier quotes as possible from multiple companies to get the best deal.
Cheap Missouri Health Insurance: FAQ
Below are frequently asked questions about finding affordable health insurance in Missouri:
What is the cheapest health insurance in Missouri?
Cox HealthPlans offers the cheapest health insurance in Missouri, with Silver plans starting at $309 for 40-year-olds. Your ideal option may vary, so consider exploring Medica, Oscar, Aetna and Anthem (BCBS) based on your income and coverage preferences.
What are the downsides of a cheap health insurance plan?
Compared to higher-priced plans, cheap health insurance has higher out-of-pocket costs, including deductibles and copays. More expensive plans reduce out-of-pocket expenses and offer more extensive health care coverage.
How We Decided the Cheapest Health Insurance Companies in Missouri
MoneyGeek obtained data directly from the Centers for Medicare and Medicaid Services (CMS) on available health insurance plans in Missouri based on consumers aged 18, 26, 40, 50 and 60.
We considered the cheapest overall to be those with the lowest monthly premium costs for 40-year-olds, as most in the state are near this age demographic, and for simplicity. However, cheaper plans tend to have higher out-of-pocket maximums and deductibles, meaning you may pay more if you receive care.
