Your reply interests me. I considered modifying my internal medicine practice to such a model around 12 years ago. I was going to call it a "boutique practice." Would enroll about 300-500 people at around $1500 apiece. Subsequently decided against it as, aside from change in the reimbursement model, this was already the type of practice I had. Also, sometimes such practices attract the "worried well" which personally is not my favorite patient group to see. At that time I was solo, now I have two additional partners. We practice "old fashioned" medicine, without physician extenders, still see patients when in need of hospitalizations, if there is a problem, we see the patient that same day. We are comfortable financially, but certainly not wealthy. Enjoy the diversification of humanity. We see people for wellness, but primarily for chronic and acute illnesses. We see privately insured patients, Medicare, and probably 2-4% Medicaid and do not turn people away as related to ability to pay. I have been the physician to Fortune 500 CEOs, governors, US Senators, and members of cabinet. Likewise, have people with nary an education, etc.
Fact is, these concierge practices are pretty much what medicine use to be. The Medical Home concept is equally silly - this is simply "old fashioned" medicine.
