I'm sorry I was responding to mpeters, I was basically saying that the social workers are a great asset to help figure out problems with anything really not just Insurance, so I apologize I was not responding directly to your situation.
I'm in Arizona and the Mayo here dosnt have primary care doctors so I'm not familiar with how Insurance works with Mayo primary care. I personally use a non Mayo doctor for my primary. So maybe you may have to seek a non Mayo doctor for primary care.
