At this point, sates have all sorts of criteria on who has what priority.
But whose job is it to decide if a given person fits the criteria?
Like, I have had cancer. I haven't had any tumors detected in several years. But do I "have" cancer? I mean I hope not, but I still spend medical money because of my cancer, and I'm still at elevated risk for recurrence.
I got hit by a car on my bike a few years ago and got a concussion, which we now know causes permanent brain damage, even if each instance doesn't cause much. Do I have a neurological impairment?
I suppose one answer is, if I can get any licenced doctor to write a note saying I do, then that should be acceptable. But still, whose job is it to look at my documentation, compare it to the state's criteria, and confirm that I qualify?
That's the sort of question that can be surprisingly murky in healthcare (for example, there's a concept of "primary" insurance and "secondary" insurance but no one knows whose job it is to classify a patient's insurance that way)
