Coinsurance
The percentage of a bill you pay after your deductible is met.
What it actually means
Coinsurance is different from a copay — instead of a flat fee, you pay a percentage of the cost. An 80/20 plan means the insurer pays 80% and you pay 20%, until you hit your out-of-pocket maximum.
Example: After meeting your deductible, a $1,000 hospital bill under 20% coinsurance costs you $200.
