My wife and I have different doctors. Both are doing exaactly as you describe - 600 patients with a yearly enrollment cost.
We are both joining as we believe:
If you like your doctor, you can keep your doctor
Because both our doctors want nothing to do with this trash heap of a government run system. We know both doctors well. They are trimming their clients to about 1/2 of what they serve now
Neither voted for the clown
Don’t be too reassured. Eventually the medical boards will put an end to this inequality by restricting or threatening their licenses to practice. Comrade...it is only just to do so, no?
