There are laws and medical licenses for this reason. There are always incentives to cut costs, whether administering medicine for cash from patients or for insurance payments. At least with this model, the patient is choosing the doctor, paying him, and receiving he care. So if he cuts corners in a way that makes the patient less satisfied (eg. very short appointments, cramped/dilapidated office, bad on-time performance, office in a bad part of town), the patient can choose to go elsewhere. If it's the one place the patient's insurance will cover thanks to the reduced price from cutting those corners, the patient has no real choice.
