Insurance for co-payment

The Medishield and Private Shield plans require the patient to co-pay the part of the hospital bill, comprising of the deductible and co-insurance. Some insurance companies offer a rider to cover the co-payment. Many insurance agents sell the rider as an attractive benefit. In my view, it is all right for the consumer to self-insure and make the co-payments out of  savings (e.g. Medisave), rather than pay the insurance premium (that includes a loading for expenses and profit).
