I don’t know, but my uncle is a urologist in Florida and he has made less money each year for the past 10 years from Medicare. That means that 11 years ago he made more than what he’s making today. Medicare might cover the cost of the procedure, but he still has to keep up his license, take classes, maintain an office, compensate his staff, etc.
And don’t forget malpractice insurance! One of his former partners is being sued for malpractice and my uncle, according to malpractice laws, is liable for a percentage of what his former partner can be sued for. Even though he did not even see, consult, or touch the patient who is suing.
