I alway felt that oil extraction would have the same affect.

Sorry no information in this comment I'm just throwing out there that in my opinion since insurance companies are increasingly becoming the payors for services rather than individuals it seems stories like this are becoming more prevalent. I mean, and I stand to be corrected it seems that the medicare system now has a "watchdog/whistleblower" vis a vis the insurance companies. It appears to me insurance companies don't like to pay the costs it used to be OK for the average joe to mortgage their house/ruin their future for.
