I cannot purchase car insurance across state lines. I have vehicles in Alaska and one in another state. It is the same insurance company but each state has its' own rules to abide by and I have to purchase a separate policy in each state and my insurance is from that state. Besides why if you live in Alaska would you want to purchase a health insurance policy in another state that is cheaper to reside in and that would pay your medical expenses the same rate as the cheaper state, that in itself would leave one with a high out of pocket expense factor, as it comes to Alaska, cheaper is not always better. So if your cheaper out of Alaska medical insurance policy pays at 70% rate of reimbursement for a doctors visit and the costs approved by the insurance company is 75. for a doctors visit and Alaska's doctor visit is 170. over time this will add up to a lot of money for the insured.
