The healthcare financing mechanisms and volumes don’t correspond with the development requirements of the sector. Any state, including RA, needs large-scale financial resources to ensure universal health coverage of the population, train the necessary number and quality of specialists, create centers equipped with the latest medical equipment, and provide quality services. Along with this, the spread of chronic diseases in the country, the aging of the population, and significant out-of-pocket costs require the introduction of a mandatory health insurance system. The main goal of the research is to define the mechanism of the phased implementation of compulsory health insurance and the calculation of the financial burden of each stage of that system, as well as the calculation of the per person annual insurance premium in case of introduction of compulsory health insurance in RA.
