You don't think physicians make medical decisions based on fee schedules? I don't think anyone is intentionally causing harm for fees, but when there's conflicting evidence concerning the risks and benefits of different procedures its very easy to let yourself be convinced that the correct management is the financially advantageous one. I don't think there was anything unfair about this comment.
On of the best studied examples of this is reimbursement schedules for C-sections. Multiple studies have found that the differential in reimbursement between C-sections and SVDs is directly related to the rate of cesarean delivery. I'm sure none of the OB-Gyns truly believed that they were performing an unnecessary procedure. Interestingly the few studies on populations that underwent a sudden rapid change in reimbursement show no change in physican C-section rates, strongly suggesting that physicians continue to adhere to what they believe is the standard of care. However the standard of care that they adhere to reliably matches the fee schedule they have spent most of their career practicing under, given enough time physicians seem to generally convince themselves that the best financial decision is the right decision for the patient. I'm pretty sure that people in states with high fee differentials do not have more indications for cesarians than patients in states with equalized pay for deliveries, so I think there is a case to be made for getting rid of fee for service.
