Cigna/Allegheny Health Network conflict: strategies to not lose my doctors?

So I got a very upsetting letter from Cigna (my employer health ins) today, that says that they haven’t reached an agreement with Allegheny Health Network (1 of 2 huge health insurance/hospital conglomerates in Pittsburgh), and if they can’t reach an agreement than on July 1, I will basically lose my entire health team, and access to roughly half the medical facilities in Pittsburgh.

I am Type 1 diabetic, my diabetes management is pretty good, but it’s reliant on having a knowledgeable endocrinologist and CDE, and my GP is literally the best doctor I’ve ever had and has helped move the needle on my health in a way no other doctor has, while also doing this thing called “treating me like a human being”. Shocking, I know.

So is there anything I can do? I really don’t want to up end my care because it’s such a huge pain in the ass to shop for doctors when you have a chronic illness, and the time lapse between visits can mean I run out of insulin or pump supplies. There’s a brief mention of “continuity of care” in the letter, which I’m assuming means “your care is so complex/requires ongoing care and it will be disruptive to remove that from you”. Do I qualify for that? How do I get that?
