Calling healthcare a human right is implying that we have the right to take from others what we need, even if indirectly via the police-power of the state (i.e., threat of violence or actual violence if necessary). To take this further, it means we have the right to a portion of another citizens labor.
Now, don't get me wrong. Talking about what governments should provide their citizens as part of their benefits package is important, but calling healthcare a right is a stretch. None of the rights on the UN or US Bill of Rights involve coercion towards other citizens to provide said rights.
