How to Choose the Best Plan in Missouri
- Check your doctors: Confirm your primary care doctor and any specialists are in-network before selecting a plan.
- Run the total cost math: For healthy people, Bronze HDHP + HSA often beats Gold PPO by $1,500–$3,000/year including tax savings.
- Check your prescriptions: If you take maintenance medications, verify formulary coverage before enrolling — drug costs vary dramatically between plans.
- Consider the out-of-pocket maximum: At full premium (no subsidy), prioritize a low out-of-pocket max over a low deductible.
