I know of about 6 pods who have done it successfully. I'm sure there are more. Most, but not all of the ones I know of have marketed their plan to some extent via books, podcasts, memberships, courses, etc. I have bought a couple of the books and found that much of the content covers why to opt out and general business principles. But the real question is how to get patients. My practice has been a hybrid (original Medicare and cash only) until recently when I decided to opt out of Medicare. I would say that the way to pull it off is to have a solid business (accounting, taxes, marketing, etc) education/foundation, avoid debt, live below your means (Dave Ramsey principles), keep overhead low, serve your patients, and slowly drop insurance plans. It doesn't happen overnight, it took me about 7 years to feel ready to take the plunge. From what I can see today, I think it's going to become easier to do and more popular as inflation rises and it will become more difficult to serve patients at the level of payment provided by insurance.
