Private practice family medicine still possible?

Still possible for FM doc to start a private practice after residency? I totaled up bills average around 200-220k per year with three employees. Estimating the average physician sees approximately 18 patients per day if the schedule is fully booked for 240 work days out of the year approximately 4320 visits per year. Average reimbursement for medicare is less than 50$ per visit while medicaid is less than 75$ so 50/50 practice would earn 62.5$ per visit or 270,000 per year working 9 hour... Private practice family medicine still possible?
