altruistic donation n.
And he's giving it to a stranger.
Altruistic organ donations like Kravinsky's are exceedingly rare. The United Network for Organ Sharing says that of the 56,221 kidneys donated by living people in the past 15 years, just 133 were altruistic donors who offered a kidney to a stranger.
Kravinsky, 48, said he's giving away a kidney because "It's the moral thing to do."

Supplying their needs can be "quite lucrative," said Dr. Roger W. Evans, the director of health services evaluation at the Mayo Clinic in Rochester, Minn., and the author of several studies on transplantation costs. "It's like a car at a chop shop. Somebody's making a handsome fee off of processing the parts."
The somebody includes everyone except the donor and the donor's family. Transplant agencies have long preferred it that way, saying that poor people might put themselves at risk by becoming sources of spare body parts for the rich, and that paying for organs would alienate the altruistic donors on whom transplant agencies now depend.

However, it seems likely that more altruistic donors will apply, if only because the need for organs in so acute. In the U.S. alone, more than 80,000 people are waiting for an organ (55,000 of those require a kidney), and the UNOS estimates that number could rise as high as 100,000 by the end of the decade.
Note, too, that although the phrase altruistic donor in the sense defined above dates to 1994 (see the earliest citation, below), there's an earlier sense that refers to people who donate blood to be used by strangers (which applies to most people who give blood), which goes back to 1985.
