Deny coverage, delay and argue. Even if you eventually do have to pay for coverage some of the patients will die before then, saving money statistically.
The oncologists described the serious adverse event as “delay of treatment” 96% of the time, “denial of treatment” 87% of the time, “disease progression” 80% of the time, and “loss of life” 36% of the time.
Just a financial perverse incentive. Once someone demonstrates a expensive chronic condition you save money by exiting them from coverage as fast as possible. Either through rejections, denials, or waiting out their deaths... Not to mention sick people are usually not in a good position to fight a Kafkaesque nightmare of bureaucracy
