1.1     Background of the study
Health care insurance plan has been a growing concern to many developing countries in recent times. Given that health insurance is designed to cover formal and informal sectors, rural and urban locations, low and high income earners, it becomes critical as well as a challenge for developing countries as they seek to design, operate and manage effective health insurance system that benefit all citizens. According to Mossialos et al. (2002) there are basically five forms of health financing available to any country. These include taxation; social health insurance; voluntary and private insurance; out-of-pocket or cash-and-carry; and donations. It is said that identifying a sustainable source of financing health care in the world has indeed become a major issue for discussion across the world’s powerful institutions and stakeholders.
The United Nation and other groupings and organs representing the continents of the world are developing strategies for sustainable health care insurance plan. According to the World Health Organization (WHO), supporting adequate, sustainable, equitable and effective health financing to improve health outcomes is one of the most important goals of the World Health Organization. The Executive Board of WHO and the fifty-eight World Health Assembly have discussed and provided strategic directions on sustainable health financing, universal coverage and social health insurance. Health insurance is insurance against the risk of incurring medical expenses among individuals. By estimating the overall risk of health care and health system expenses, among a targeted group, an insurer can develop a routine finance structure, such as a monthly premium or payroll tax, to ensure that money is available to pay for the health care benefits specified in the insurance agreement. The benefit is administered by a central organization such as a government agency, private business, or not-for-profit entity. According to the Health Insurance Association of America, health insurance is defined as “coverage that provides for the payments of benefits as a result of sickness or injury. Includes insurance for losses from accident, medical expense, disability, or accidental death and dismemberment”
1.2   Statement of the problem
Health care insurance has become a global challenge to all countries and all persons. The ability of national governments to provide funding for health care and to sustain the funding is a huge responsibility, Nigeria is no exception.

1.6   Significance of the study
Health insurance is a health insurance risk hedged against the probability that if and when someone unexpectedly becomes sick, requires expensive treatments, or is at the mercy of a chronic condition that requires long-term care they will not fall into dire financial straits. It is a benefit provided through a government agency, private business, or non-profit organization. High-quality health care affects health and wellness. A health insurance policy is a contract between an insurance company and a policy holder intended to safeguard against high and unexpected health care costs. Although policy-holders pay a monthly premium, co-payments, co-insurance, and deductibles, it is expected that the total is far less than that required if paid fully out-of-pocket. Coverage from a health insurance policy or a public health program can greatly relieve the financial burden of health care expenses. Those who are uninsured or under insured can experience financial strain and require assistance from alternative funding sources which may not be available at that time. This study will be educative as it will inform people about the enormous benefit of health care insurance plan and it will also be a reference point for researchers.
