On the other hand the providers have financial incentive to provide unnecessary and excess medical services. Different types of moral hazard like as ex ante and ex post moral hazard; hidden information and hidden action moral hazard; provider and consumer moral hazard may arise due to insurance coverage. These lead to negative consequences such as consumption of unnecessary care services, alteration of consumption pattern for inefficient use of resources, welfare loss, and an increase in the health expenditures.
