Interesting, but hardly conclusive. Two problems with the conclusion you are trying to make:
Cheaper health care != less money spent on health care. Consumers might purchase more health care even as prices come down (resulting in more money spent).
This data doesn't show the direction of causality. It could just as easily reflect doctors chasing money as it could reflect prices increasing as a result of doctors becoming available.
(Similarly, states with more illegal immigrants tend to spend more money on farm labor. Do illegal immigrants raise the prices of farm labor?)

Still, it's interesting data to see.
