Do you travel a lot? If so, does your EPO have a national network?
One of the things I have come to hate about ACA plans is that *none* have non-emergency coverage out of state. (In many cases, even out-of-metro) since I've been aware of this, now I have to consider medical travel insurance, even inside the US. We have one kid, and usually are traveling for family events, meeting lots of people. Should a worse-than-typical, but not ER event happen, particularly if there are any diagnostics involved, that could become a large price.
My former employer had a Blues PPO plan, and I used to laugh at some billing, which could pass between three of them at a time. (The state where the care occurred, the state we lived in, and the "home" state of the company, which administered the plan) Boy, I wish I could even opt for that, now.
