I've anecdotally done some research and in SoCal a true concierge medicine for what I would be looking for with a brick-and-mortar location and imaging on-site is ~$5000/yr.
Curious what that fee covers beyond having direct access to the physician (and even there, beyond just consultations). If you needed imaging work or even procedures or surgeries - would that be extra fees?
Can't speak to the parent posters' experience, but for me, it covers a lot of imaging, routine bloodwork, cheap Rx for a lot of basic medicines (think blood pressure medications, diabetes meds.) I can get a full basic blood panel (CBC, CMP, LDH, ALT, TPT..etc) done for a few bucks instead of paying several hundred, that alone has saved me a good chunk of change over the years.
One of the huge benefits for me has been that I have much simpler access to specialists. They are somehow able to punch through a lot of the scheduling bullshit for me, so when I do need to see a specialist, I am not waiting for weeks or months; Sometimes I've been able to get appointments at a specialist through them within a few days instead of the few weeks it would have been had I tried doing the same myself.
