Coinsurance is a type of health insurance where the policyholder and their insurance company share the cost of a covered claim. It's different from a co-payment where the policyholder pays a set amount for a service or product and the insurance company pays the remainder.
When a policyholder has coinsurance, they will be responsible for paying a specific percentage of the cost of a covered claim. The insurance company will cover the rest. For example, if the coinsurance amount for a claim is 20%, and the service costs $100, the policyholder will be responsible for paying $20, and the insurance company will pay the remaining $80.
The amount of coinsurance held by the policyholder is typically determined by the terms of the health insurance plan, but it can also be impacted by the type of service or product that the policyholder needs.
The policyholder and the insurance company will both share the cost of a covered claim and this is important for both parties because it helps keep the cost of insurance lower for the policyholder and helps the insurance company manage risk.
