These three words decide how much you pay every time you get care. Most people mix them up — not because they're not smart, but because nobody ever explains them. Here's the plain version.

A copay is a fixed amount you pay at the visit. $25 to see your doctor. $50 for a specialist. You pay it at the front desk, and that's usually it for that visit. Copays are the simplest of the three — what you see is what you pay.
Your deductible is how much you pay out of your own pocket each year before your insurance starts paying its share. If your deductible is $2,000, you pay the first $2,000 of covered care that year. After that, insurance kicks in. Many plans still cover some things — like checkups or a doctor visit with just a copay — before you hit your deductible. Your plan documents say which.
After you meet your deductible, coinsurance is how the bill gets split. If your coinsurance is 20%, you pay 20% of the bill and insurance pays 80%. So a $1,000 procedure costs you $200 — once your deductible is met.
A typical year looks like this: you pay copays for regular visits all year. For bigger care — a procedure, a hospital stay — you pay full cost until you hit your deductible, then you pay your coinsurance percentage, and once you hit your out-of-pocket maximum, you pay nothing more for covered care that year. That last number is the one that protects you.
Usually no. On most plans, copays don't count toward your deductible — but they almost always count toward your out-of-pocket maximum. Your plan documents or insurance card hotline can confirm.
Insurance starts sharing the cost. Instead of paying full price, you pay your coinsurance percentage (often 10–30%) until you reach your out-of-pocket maximum.
Plans trade premiums against deductibles. A lower monthly premium usually means a higher deductible. Neither is wrong — it depends on how much care you expect to need.
