Look at the crude math behind this business model. Assume every pt pays a minimum ~$75 per visit (people will pay this easily, they already do as copay often), and you are doing 40 pts a day (this is not unheard of especially since you have way less paperwork to do). You will rake in ~800K in sales working 5 days a week for 50 hours. If you work the same hours as a regular PCP which is 60 hours/week, then you might sell ~1 million dollars in services per year. Pay your staff, insurance and other overhead and you will still be better paid than your peers, with more pts under your belt and less paperwork (some of which will only result in $35 reimbursements). Believe it or not, this market is sitting right under the very noses of our so called "lowly paid PCPs". Most will give you 400 reasons why it cant work, while the few savvy ones will find 400 ways to make it work. That is why society has only a few rich folks, while most are not.
