What is Co-Insurance
A kind of cost-sharing in which the insurance company pays for a percentage of the cost of medical treatment, and the patient pays the rest. This is separate from deductibles and premiums. For example, if the health insurance or plan’s allowed amount for an office visit is $100 and you’ve met your deductible, your co-insurance payment of 20% would be $20. The health insurance or plan pays the rest of the allowed amount.
