Deductible, Copay, Coinsurance: What Do These Even Mean

Deductible: the amount you pay first

Your deductible is what you pay out of pocket before your insurance starts covering costs for most services. If your deductible is $1,500, you're generally responsible for the first $1,500 of covered care in a year before your plan kicks in more fully.

Copay: a flat fee per visit

A copay is a fixed amount you pay for a specific type of visit, like $30 for a doctor's visit, regardless of the total cost of that visit. Copays often apply even before you've met your deductible, depending on the plan.

Coinsurance: your percentage of the bill

After you've met your deductible, coinsurance is the percentage of costs you still share with your insurer. An 80/20 split means your insurer covers 80% of a covered cost, and you cover the remaining 20%.

How they actually work together

Picture a $2,000 procedure with a $500 remaining deductible and 20% coinsurance. You'd first pay the $500 deductible, then 20% of the remaining $1,500 — meaning your total cost would be $800, with insurance covering $1,200.

• Deductible is the threshold you pay before broader coverage starts
• Copay is often a flat per-visit fee, separate from the deductible math
• Coinsurance is your ongoing percentage share after the deductible is met
• Out-of-pocket maximum is the most you'll pay total in a year, after which insurance covers 100%

The number that actually protects you most

Your out-of-pocket maximum is the real safety net — once you hit it, your insurer covers 100% of covered costs for the rest of the year. It's worth knowing this number even more than your deductible.
