Health Insurance is now only for the healthy.
If you are not healthy you could often be canceled.
The appeals process is winable for the unrelenting stout of heart and the litigiously savvy.
Most people just roll over after the customary initial cancelation.
This increases their profit margin. If they can keep up an appeals process until the person dies the profit margin is vastly increased.

My wife is an expert in the area of federal research of health insurance companies. PM me and I will have her respond.

Sorry it happened to you but there is one good thing...at least this thread is devoid of Martin Gibson and friends with their disgusting rhetoric of brown juice anal intercourse and such.
