Depending on how long you are here and if you have pre-existing conditions, you may want to get a low level plan at one of the local hospitals.
Keep in mind, worst case as well, there is free public health care here as well if you needed some type of emergency care (and in serious emergencies involving critical care, you might have better luck at a public hospital). And you could pay out of pocket for routine medical care or a regular check. It would in fact probably wind up cheaper if you're only here for a year or so.
