I am (generally) a big fan of doctors experimenting with different forms of medical practices. Some doctors are sole proprietors and work mostly alone in their office. Years ago, I went to a doctor who did not accept insurance and would not make appointments. His office was small since he didn’t require a billing staff and was very efficient. His prices were transparent and quite low ($35 office call in 1993).
Another physician, this one from Northern Virginia, pioneered primary care consultations by telephone. Doctalker Family Medicine would do house calls, in-office visits and consultations by phone. Each service came with a different price tag. He did not accept insurance, but his office would help patients fill out an insurance claim form for a modest fee. Most of his consultations were by phone.
