I didn’t see your reply before I posted my reply, linked below, re who pays for the costs of keep the donor “alive” until the organs are harvested.
Do you know the answer?

In the particular case you cited, I would think the recipients of the organs (or the insurance companies who paid for their medical care) should be picking up the tab.
Just step back and think about this objectively. What you have in an organ donation process is an expensive, complex procedure involving hospitals and doctors who are performing surgery on one patient for the sole purpose of providing treatment to another patient whose identity probably isn't even known at the time. It should come as no surprise that these procedures are fraught with legal and financial confusion.
