I am wondering about the the "loophole." Typically, if the provider is not in your PPO plan network you pay a higher percentage of the cost of care and may also be required to pay the difference between what the health care provider charges (which is not regulated) and what the plan deems to be "reasonable and customary" for the service. So it can get extremely expensive and often unaffordable. But it is less common for a plan to out and out not cover a provider.
I don't suppose Mayo is in her network?
