Downloaded from 2016, URBMI and NRCMS have been merged into a new type of resident medical insurance, Urban and Rural Resident Basic Medical Insurance (URRBMI), which covered the population in the previous URBMI and NRCMS. Similar to URBMI, the NRCMS and URRBMI featured flat rate contributions. However, although all enrollees paid the same premiums to the NRCMS, the benefit packages varied geographically. In addition to social health insurance, taxation and out- of- pocket (OOP) payments are the two other sources of finance for healthcare in China.2 However, the impact of these sources on healthcare financing is likely to vary.
