I don't know if you will read this, but here are some thoughts not mentioned by others.
Currently when I visit the different doctors responsible for my care it does not cost me anything over what Medicare and my supplement pay. The Doctors I visit have all seen me within an hour. We are all retired here and still people are always in "a hurry". If you are a good Internist with Geriatric specialty you would do well in The Villages under that profession. All of my specialists have been excellent and if not, I have looked for another.
Therefore, the privilege to pay a sum of money to be guaranteed to see the Doctor may be for the more affluent of TV, but not for those who are on a limited income, naturally there are both here in the Villages. Good luck in whatever you decide to do.
