how many US states have a single payer healthcare system?

Alaska's healthcare system kinda works like that, but only for Alaska Natives.
Do you mean anyone Alaska born or Native American Alaskans?
Specifically Native American Alaskans (i.e. those with a tribal ID)
Tribal Montanans have care through BIA. I wonder if BIA serves Tribal members anywhere in the US?
