Participants of Public Health Insurance (Jamkesmas) up to 2010 reached 76.4 million including poor and disadvantaged people, meanwhile participants of Regional Health Insurance (Jamkesda) reached 31.6 million people. In principle, Jamkesda program is made to facilitate the poor and disadvantaged people outside Jamkesmas quota funded by local government. This study aimed to review the accuracy of Jamkesmas participant target according to the poor criteria of Data Collection for Social Protection Program. Data source used is national socio-economic survey (Susenas) 2012. Population of this study was all households in Indonesia within 2012. Sample of this study was households selected from each block sensus. Analysis conducted was univariate, bivariate, and multivariate with logictic regression. There were 12.4% people receiving Jamkesmas, but they were not poor or almost poor. Moreover, there were 56.4% the almost poor and 41.1% the poor not yet having access to Jamkesmas. Free service is the most determining factor whether people can be Jamkesmas participants. The people who having free health services had an opportunity 5.462 times to get Jamkesmas service compared to the people who did not. Database improvement, surveillance, evaluation as well as good allocation system are needed to reduce the inaccuracy of target. Adjustment of data between Health Ministry and local health agency is useful in handling uncovered participants.
