Another thing that happens --- particularly in California, lest you think this is an IL problem --- is that comparatively minor medical conditions were used as proxies for rare but expensive conditions. For instance, if you were a woman with abnormal cramping, you might be default-denied based on a simple blacklist of uninsurable conditions because insurers were scared that might presage something expensive down the road.

The preexisting condition and recission policies of insurers prior to Obamacare were a national disgrace.
