This paper provides a detailed description of health coverage in OECD countries in 2012. It includes information on the organisation of health coverage (residence-based vs contributory systems), on the range of benefits covered by basic health coverage and on cost-sharing requirements. It also describes policies implemented to ensure universal health coverage –in most countries- and to limit user charges for vulnerable populations or people exposed to high health spending. The paper then describes the role played by voluntary health insurance as a secondary source of coverage. Combining qualitative information collected through a survey of OECD countries on benefits covered and cost-sharing requirements with spending data collected through the system of health accounts for 2012, this paper provides valuable information on health care coverage in OECD countries at a time universal health coverage is high on the policy agenda of many countries.
