The aim of this paper is to discuss the current structure of the Saudi health care system, and to assess financing healthcare services in the Kingdom of Saudi Arabia (KSA) by implementing national health insurance. The paper focuses on improving Saudi Arabia's health care system as a national health insurance system is being introduced. The aim of this policy reform is to increase investment in the healthcare sector by the private sector and to reduce government costs for health services. Access to healthcare, sustainability, costs and quality of care, adaptation of new technologies and the use of health services are all expected to have a positive impact. We are reviewing the current health literature and the latest health reform of Saudi Arabia. In this area, the importance of public health: improving the health system is intended to improve the outcomes of community health. Whether it will have the desired impact will be clear as Saudi Arabia embarks on this move. In addition, if Saudi Arabia succeeds in providing high-quality healthcare to this segment of the population, expatriate healthcare in different countries is a challenge; other countries will follow the Saudi model. The purpose of this study is to analyze the existing structure of Saudi health systems, to assess the funding programs for health care in the Kingdom of Saudi Arabia (KSA) by introducing national health insurance schemes and to propose improvements.
