Coinsurance refers to your share of costs of a covered health care service after your deductible has been met. It serves as a way of indicating that you and your insurance carrier each pay a share of eligible costs that add up to 100%. While some plans pay for the entirety of medical costs in these instances, others don’t cover the whole amount.

You’ve paid $2,500 in health care expenses and have met your deductible for the year. Anytime you visit the doctor after that point, you and your health insurance provider share the costs. 80/20 is a popular split; this means your insurance provider would pay 80% and you’d pay 20%.
