I was trying to rememeber the name of that group. I am actually on it--havent signed in and checked it for a few days. But yes, you do want to join that listserve.
You really want to limit the amount of insurance that you take.
Opt out of Medicaid & Medicare from the start--even if you are in Florida. To jump-start you with some patients, you might want to get on one or two insurers that pay better than the others or one that has a lot of market share. But make sure they pay decently--well, that is decently for an insurance company, because they all cheat you docs so much it would be funny if it wasnt so disgusting. They are just parasites.
Look into ways to attract patients that are willing to pay "out of network" fees and/or those completely uninsured. Or who have only "catastrophic" insurance. Then you can actually get paid for the services you provide.
