What’s the Difference Between Co-pays and Co-insurance?

Copayment is that what % you will pay and the balance is to be paid by the insurance company.
Coinsurance is not applicable to individual’s health insurance policy. It is applicable to insurance of large plan with premium say Rs 20 lakhs and above where 2 or more insurance companies share the premium and the risk. The insurance policy is issued by Insurance Company having maximum share, then it collects the premium and gives cheque to other insurance companies. At the time of claim, they pay the claim and collect the amount from the insurance companies.
