Yup, transplant surgeons are highly compensated surgeons. I can't find any website that lists avg salary, but my understanding is that they can make anywhere from 300K-1 million per year depending on how many transplants they do. One reason that this is such a lucrative field is that insurance co's often won't pay for transplants, so patients end up with huge out of pocket expenses or the funds come from donations (1 lung transplant costs patients ~200,000 which patients have to demonstrate to the hospital that they have in cash before receiving the organ at my hospital). Out of pocket fees are almost always more generous in terms of physician reimbursement fees. Of course not all of this goes to the surgeon, transplants are really expensive because of all the followup care and transplant medicines that patients are chronically on. Harvesting organs such as the kidney can be done by general surgeons, it's a laproscopic procedure these days. CT surgeons do handle the heart and lungs, and there is a transplant fellowship that allows surgeons to handle other organs.
