Know what a service will really cost you.
A copay is a flat fee. Coinsurance is a percentage of the bill after your deductible. Enter the numbers on any medical service and see exactly what you pay, what insurance pays, and which one is cheaper for you.
The service
Deductible left is how much of your yearly deductible you still owe before coinsurance starts. Copay services usually skip the deductible.

Copay and coinsurance, explained
Copay vs Coinsurance
Copay: fixed dollar amount per visit (e.g., $40 specialist). Coinsurance: percentage of cost (e.g., 20%). Below the breakeven point, copay is cheaper. Above it, coinsurance.
Breakeven Math
Break-even = copay / coinsurance%. $40 copay / 20% = $200. Services costing more than $200 = coinsurance better. Below that, copay wins.
Which Plans Use Which
HMO/PPO often use copays for office visits, coinsurance for procedures. HDHP/HSA usually coinsurance for most services. Read your plan to know which applies where.
Out-of-Pocket Max Caps
Both copays and coinsurance count toward OOP max. Once hit, insurance pays 100%. Big expensive services after OOP max are free to you.
Common questions
Why offer two systems?
Copays simpler for predictable costs. Coinsurance aligns your incentive with insurance (you share % cost). Plans use both.
Does deductible apply to both?
Usually yes. Both copay and coinsurance kick in after deductible met. Some plans have copays before deductible.
What's better for someone with chronic conditions?
Copays, predictable, capped per visit. Coinsurance better for occasional services with known low cost.
Can I negotiate cash price below my copay?
Sometimes, especially imaging, lab work. Some providers offer 30-50% cash discount. Won't count toward deductible/OOP max though.
How is this different from premium?
Premium is monthly fee for coverage. Copay/coinsurance are per-service costs at point of care.
Estimates for planning only. Your real cost depends on your exact plan, whether the service is billed as a copay or coinsurance, the allowed amount your insurer negotiates, your remaining deductible and your out-of-pocket maximum. Check your plan documents and the explanation of benefits.
