Hi cheynewalk, what you're talking about is the new national healthcare system (BPJS) that started last year. I think most of what you need to know can be found in this thread:

. . . gives you free access to hospitals, dentists and pharmaceuticals.
Yeah, in theory, but I'm not sure this is entirely true. Also, whether you'd want to use the actual services offered might be a relevant question too. e.g. low quality, disorganised or too long a waiting period. But for the price, it's definitely worth signing up and giving it a try.
