Learn Your Plan
I've had Aetna for years and I hated it at first, but that's because I was uneducated about insurance. I've learned a lot and the best thing that you can do is to stay in-network, check out the clinical policy bulletins, and sign up for Aetna navigator so you never have to call member services. You can do everything yourself, even change your address and order an ID card or inquire about a claim. You just have to be pro-active because its your health, not theirs.
