Coinsurance
Health insurance coinsurance are health insurance plans that requires an insured person to pay a stated percentage of medical expenses after the deductible amount, if any, was paid.  Once any deductible amount and coinsurance are paid, the insurer is responsible for the rest of the reimbursement for covered benefits up to allowed charges: the individual could also be responsible for any charges in excess of what the insurer determines to be “usual, customary and reasonable”. ¨ Coinsurance rates may differ if services are received from an approved provider (i.e., a provider with whom the insurer has a contract or an agreement specifying payment levels and other contract requirements) or if received by providers not on the approved list.¨ In addition to overall coinsurance rates, rates may also differ for different types of services.
