I don't know anyone who has a practice consisting
entirely of Medicare patients. If they do, they're probably going to be taking home less than the MGMA average, unless they have incredibly low overhead, or they're "making it up on volume", as the saying goes. In order to preserve our income, most of us prefer to see a diverse mix of Medicare and other higher-reimbursing payers. IMO, it's a good idea to keep an eye on your numbers in order to avoid getting too heavily weighted towards Medicare. Personally, I try to keep Medicare at no more than 25-30% of charges.
You manage your appointments according to your practice style. I schedule patients in 15-minute slots (30 minutes for new patients and physicals). If there are too many issues to deal with in one visit, we'll take care of the most important things first, and I'll ask the patient to schedule another appointment for the rest. It's not just Medicare patients who have a lot of issues. I'll sometimes tell patients, with a smile, "I
am the 'doctor for all of you', but not in one visit."
I don't see why not. If anything, FPs are going to be in even bigger demand than they are right now.
