Dr. Mark Kot, an urgent-care specialist and the owner of Southampton Urgent Medical Care in Southampton, N.Y., is the anti-Obamacare doctor. He does not participate in most insurance plans and is not in any Affordable Care Act network. He feels sorry for the patients with this restricted insurance, and when they come to his door with a bad cough or a painful foot and ask to be seen, he does his best to provide them great care for a limited cost.
