All three are medical charges you must pay out of your own pocket, even if you have insurance. Deductibles are a specific amount you must accumulate and pay each year of covered health services before benefits are provided by your carrier. Plans may also have separate individual and family deductibles and/or deductibles for separate services. Copayments are a set fee the member pays to providers at the time services are provided. Copays are applied to office visits, emergency room visits, hospital admissions, etc. Coinsurance is a form of cost sharing. After your deductible has been met, plan will begin paying a percentage of your bills. The remaining amount, known as co-insurance, is the portion due by the patient.
