Health Insurance Terms Explained: Deductibles, Copays, Coinsurance & More

2026-04-06 · 2 min read

Premium

Your premium is the monthly amount you pay for your health insurance, regardless of whether you use any medical services. Think of it like rent — you pay it every month to keep your coverage active.

Deductible

The deductible is the amount you pay out-of-pocket before your insurance starts covering costs. If your deductible is $2,000, you'll pay the first $2,000 of covered medical expenses yourself. After that, your insurance kicks in. Preventive care is typically covered before you meet your deductible.

Copay vs. Coinsurance

A copay is a fixed amount you pay for a service (e.g., $30 for a doctor visit). Coinsurance is a percentage you pay (e.g., 20% of a hospital bill). Both apply after you've met your deductible, unless your plan specifies otherwise.

Out-of-Pocket Maximum

This is the most you'll ever pay in a plan year. Once you hit this number, your insurance covers 100% of covered services for the rest of the year. This is your financial safety net.

Network: In-Network vs. Out-of-Network

In-network providers have negotiated rates with your insurance company, meaning you pay less. Out-of-network providers haven't, and your costs can be significantly higher — or may not be covered at all. Always check if your doctor is in-network before scheduling.
