Key Health Insurance Terms to Know
Before choosing a plan, you must understand the essential terms:
-
Premium – The amount you pay monthly for your health plan.
-
Deductible – The amount you pay out-of-pocket before your insurance starts covering costs.
-
Copayment (Copay) – A fixed amount you pay for a covered service (e.g., $25 for a doctor visit).
-
Coinsurance – A percentage of the cost you share after meeting your deductible (e.g., 20% of a hospital bill).
-
Out-of-Pocket Maximum – The most you’ll pay in a year before your insurance covers 100%.
-
Network – Doctors, hospitals, and providers your plan works with.
Pro Tip: Always read the Summary of Benefits and Coverage (SBC) to compare plans side by side.
