Coinsurance意思

Coinsurance is a term used in the insurance industry that refers to a policyholder's share of the cost of a medical service or prescription drug that is not covered by the insurance plan. It is typically a percentage of the total cost, such as 20% or 30%, and is in addition to any deductibles that may apply.

For example, if a policyholder has a coinsurance rate of 20% and a medical service costs $1,000, the insurance company will cover 80% of the cost ($1,000 x 0.80 = $800), and the policyholder will be responsible for the remaining 20% ($1,000 - $800 = $200).

Coinsurance is different from a copayment, which is a fixed amount that the policyholder pays for each visit to a healthcare provider or for each prescription filled, regardless of the total cost of the service or drug.

Coinsurance can be a significant cost for policyholders, especially if they require expensive medical treatments or frequently need to see a healthcare provider. It is important for policyholders to understand their coinsurance rates and any other cost-sharing requirements of their insurance plan to avoid unexpected medical bills.
