I have Aetna, and their provider pages aren't up-to-date. If you do need to look at other lists, the Psychology Today lists do allow people to limit searches by insurance provider. They also mention specializations and in some cases sliding scale info. I won't say their lists are totally up-to-date, but as I wrote, they've yielded more for me than my Aetna list. As you surely know, Aetna has various plans. I've found therapists on Psychology Today that accept my Aetna that weren't on the Aetna list yet.
