It's highly unlikely this is true on a wide scale.  Capitalism does work in the long run.  If I was a Dr in WA and just read that I could make 10X as much in AK I would be on the way up, maybe I'll only charge 9X as much and get more customers.  But wait a Dr from CA had the same idea and now it's only 8X.  This would certainly get driven down to the same premium AK pays for everything else.  The health care system does have many problems, but AK paying 10X times for services is not one of them.
