RE: My doctor is part of a medical group with the local big hospital.
Is he NOT allowed to have a private practice? Why can’t you go to his home office like many people used to do?

See above.
With very few exceptions all doctors in the area are part of one physician group or another. Because of Obama(don't)care the paperwork has become so onerous that the days of a doctor's office with a couple of doctors and nurses and a receptionist that does the office work are over.
I don’t know the situation, but I am going to go out on a limb and guess the answer is the usual one: the cost of the malpractice insurance, or the rules that come with it, is probably the prohibitive factor.
