Doctor Kickback Lawsuit Settled

Ameritox, a drug testing company based in Texas, has settled a false claims lawsuit for $16.3 million. The lawsuit alleged that the company paid kickbacks to doctors in exchange for business.

I would be interested in the fate of the doctors who received the kickbacks. It is like buying stolen goods. For stealing to be profitable, there typically needs to be a market for the stolen goods. This is why buying goods you know to be stolen is a crime. Do the doctors skate off with slightly fatter wallets?
