Is Scottsdale a primary care clinic? I do know that in order to go to a primary care clinic, you need to have started going there prior to being on Medicare. They, I believe, will accept Medicare patients who started there while on another insurance and transitioned into Medicare. Another way to get in the door is to go through the ER. A neighbor of ours went to the ER in Jax and then was able to see drs. In the clinic…..not the primary care clinic but the one with the specialists. It’s very confusing to someone who doesn’t get how this all works. Yes, that 15% extra that Mayo charges could get expensive if your secondary insurance doesn’t cover most of it. Thankfully, ours does and I’m sure I didn’t pay more than $50 out of my pocket all last year.
