Having almost completed my degree in Health Information Management/Technology (less than one month to go!) I can tell you its definitely not the norm across the country. The technology isn't that advanced yet. No one wants to pay for the health information exchanges that it would require to transmit information from one system to another since they are not all compatible with each other.
I think we are in the same state (MN), and I know for sure that our state isn't linked. Insurance claims are not accessible except by those who made the claim, and the insured party. There are no state laws on required information sharing.
With that degree, you should be pretty much assured of always being employed, even as everything else crumbles around us. In January, I left my job in Healthcare IT, after 10+ years. Also, some years ago, I worked a couple of years at a different healthcare company, as a field engineer. I'm not sure what my next job will be, but I plan to stay far from healthcare, if at all possible. Good luck to you and I send you early Congratulations on completing what must surely be a demanding degree.
