Who sets up the salary of doctors and nurses in private practices? Is it the lead doctor that considers ths salary? Is it by hour or by the procedure and appointments? I have seen the receipts I get after every appointment listing the charges through insurance for my exam and tests. That would mean that they would bring in a different amount of money every week/month/year. So how do salaries stay stable?
Are you in the US? For a private practice, the doctor or doctors are generally self-employed owners of the practice, so they get paid their share (if it’s a group) of the money collected from patients and insurance companies, minus the expenses of running the practice. And yes, their income could vary from year to year, or from week to week.
Nurses are generally employees of the practice, so get salary or hourly wages just like any other job.
