Coinsurance
コインシュアランス(自己負担割合) (koinshyuaransu (jiko futanwari))
Coinsurance is the percentage of costs you pay for a covered service after you have met your deductible. For example, if your plan has 20% coinsurance, your insurer pays 80% and you pay 20% of the allowed amount. Coinsurance applies to most in-network services and continues until you reach your out-of-pocket maximum, after which the insurer covers 100% of covered costs for the rest of the plan year.
Coinsurance differs from a copay in that it is a percentage rather than a fixed dollar amount, so your share varies with the cost of the service.
