I'm surprised they're able to recruit anyone to this trial under those conditions.

While you're obviously hoping that this trial will benefit you, from another perspective, this is mostly an experiment, which presumably will primarily benefit a pharmaceutical/ biotech company. It is not the insurance company's job to subsidize a drug company's research by paying for three weeks of hospitalization. As a tax-payer, I can't say I'm in favor of Medicare paying for this either.

The study coordinator seems like the person who should sort out this problem.
