Hey, I've noticed that neurosurgeons, cardiac surgeons, and ortho spine are all paid a LOT higher (with 500-700k averages in private practice) than pretty much anyone else. Since its insurance companies controlling the reimbursement, what is keeping these salaries so high? Does insurance just pay more because the doctor has trained longer? Is it equipment and or time? Or is it because the cases are more delicate and have higher risk? All three? Do you foresee reimbursement cuts?
